BACKGROUND
[0002] Embedded devices such as mobile phones, including Android,
Apple and Samsung phones, are often equipped with miniature camera
modules. These miniature camera modules typically include only a
single fixed-focus lens and an image sensor. Some of these devices
have software applications downloaded or otherwise stored on them
that permit limited choices in pre-capture camera settings, such as
exposure duration and flash setting, and some provide limited
post-capture image editing capabilities designed to compensate for
the inadequacy of the built-in optics. Image processing software is
however incapable of providing real images of objects that are too
close or too far from the device, or of scenes including multiple
objects that require greater depths of field in order to capture
them without intolerable amounts of defocus blur or of scenes with
moving objects without excessive motion-related blur, among other
imaging issues. It is therefore desired to be able to supplement
the built-in optics of a miniature camera-enabled embedded device
with one or more additional lenses or other optics.
[0003] Auxiliary lenses for mobile smartphones with camera modules
are typically clipped onto the smartphone. These clip-on lenses put
mechanical stresses on the smartphone directly along the optical
path of the camera modules that can result in distortional stresses
that can mechanically weaken the device and can distort the optical
quality of captured images. Clip-on lenses are also unstable and
often move laterally when smartphone precapture settings are being
adjusted, during image capture and when the smartphone is being
temporarily stored in a bag or pocket or on a table top. It is
desired to have a way to attach an auxiliary lens to a mobile
device in stable alignment with the optics of the built-in camera
module.
[0004] Smartphones are used for capturing digital images in a
variety of situations. In the past, a person operating a camera
could not be in the picture because of the unwieldy nature of the
camera and the camera-object distances typically involved in
capturing an entire scene that may include multiple persons and
perhaps background buildings or other objects. Some conventional
cameras include a built-in delay to allow the camera operator to
quickly duck into the scene that is based on a predetermined time
duration or that uses face recognition techniques wherein image
capture awaits a smiling camera operator to enter the scene. Either
way, it is difficult to spontaneously, stably and accurately
position and direct a camera to capture a picture without being
held by a human operator. Today, "selfies" are more commonly made
possible because smartphones and other mobile devices with built-in
miniature camera modules are permit front-side display of the
precapture image and these mobile devices are typically lightweight
enough to hold in one hand while an image is captured. Nonetheless,
it is desired to be able to more easily handle a mobile device
during a one-handed image capture.

device cases, and software applications, accessories and other
features are described below herein with reference to FIGS. 1-42 of
the drawings. Various features are illustrated in the several
example embodiments that are illustrated in multiple subsets of the
drawings.
[0115] Several embodiments of mobile camera devices, mobile camera
device cases, lens attachment interfaces for mobile camera devices
and/or mobile camera device cases, half-press/full-press shutter
buttons for mobile camera devices and functional mobile camera
device cases, and software applications, accessories and other
features are described below herein with reference to FIGS. 1-42 of
the drawings. Various features are illustrated in the several
example embodiments that are illustrated in multiple subsets of the
drawings.
[0116] FIGS. 1-10 particularly illustrate examples of lens
detection and recognition methods and devices including non-contact
and direct electrical contact techniques. That is, example
embodiments are described below and illustrated in the drawings
whereby specific lens types, of multiple selectably removable
mobile lens types each having different optical properties, are
recognizable and discernible automatically by electronics and
software embedded within the mobile camera device case. In some
embodiments, the lenses, lens holders and/or one or more features
of the lens attachment interfaces of the lenses and mobile device
cases are configured to facilitate lens recognition. Example
techniques involve the use of one or more Hall effect sensors,
inductive or capacitive sensors, and/or direct electrical
connections.
[0117] FIG. 1 schematically illustrates a mobile camera system
including a case 2 coupled around a camera-enabled mobile phone 4
or other embedded mobile camera device 4. A lens attachment
interface 6 is coupled to, removably attached to, embedded within
or formed integrally with the case 2.
[0118] A lens recognition sensor (8) is signal connected,
electrically by lens sensor connection 10, and/or wirelessly by
Bluetooth, RF and/or IR or other wireless technique, to a main
printed circuit board (PCB) 12, which includes a lens sensor
interface 14 and a processor 16. The main PCB 12 optionally
includes a Bluetooth smart radio 18. The example case 2 illustrated
at FIG. 1 includes a battery 20 which may be any of several types
such as a coin cell as shown.
[0119] A lens 22 is shown in FIG. 1 coupled along the optical path
of a miniature camera module (not shown in FIG. 1) that is an
installed component of the phone 4. The lens 22 is coupled to the
case 2 and phone 4 at the lens attachment interface 6 in stable
alignment with a lens and image sensor of the embedded miniature
camera module of the mobile camera system.
Lens Detection and Recognition
[0120] Lens recognition can be thought of as involving both lens
detection and lens type identification. Lens detection permits that
device to know that a lens that has been specially-designed to
couple with a case equipped with lens recognition components or a
standardized lens has been attached and not a foreign object or a
lens that uses a non-conforming interface.
[0121] FIGS. 2A-2C illustrate a magnetic field sensing lens
recognition technique. A precisely placed magnet 24 or subset of
magnets 24 or array of magnets 24 are built-into the lens 22
illustrated at FIG. 2A, or lens holder or an attachment to the lens
22 or lens holder. The lens sensor 28 in this embodiment, which is
built-into the mobile camera device case 2 (see FIG. 1) along with
a lens sensor connection 10 to a main PCB 12, includes a
Hall-effect sensor 30 or array of Hall-effect sensors 30. In the
example of FIG. 2A, there are four Hall-effect sensors 30 that each
either detect magnetic field or don't depending on whether the lens
22 includes a magnet at the location associated with the particular
Hall sensor 30 of the array of sensors 30.
[0122] If there are no magnets, the Hall sensors will measure 0000.
If there are four magnets, the Hall sensors will measure 1111. If
the specific lens 22 includes one of four magnets, the Hall sensors
will measure 1000, 0100, 0010 or 0001 depending on which of the
four locations that the magnet is placed. If the lens 22 has two of
four magnets, the Hall sensors will measure 1100, 1010, 1001, 0110,
0101 or 0011 depending on which two of the four locations that the
magnets are disposed at. If there are three magnets, the Hall
sensors will measure 1110, 1101, 1011, or 0111 depending which of
the four locations does not have a magnet placed there. In all, 16
different lens types can be identified using the four Hall sensors
and the binary method described and illustrated in this example.
Note that the sensors can also measure the opposite polarity, for
example with one magnet the measurement could be 0111, 1011, 1101,
1110. Multiple lenses containing a unique combination of magnets
can be detected (presence) and differentiated (uniquely
identified).
[0123] FIGS. 2B-2C alternatively illustrate a case 2 including a
Hall sensor interface 28 including four Hall sensors 30, and a lens
sensor connection 10 to a main PCB 12. A lens attachment interface
cavity 32 is defined in the case 2 of each of FIGS. 2B-2C. The lens
attachment interface cavity 32 is configured in shape and location
to permit stable coupling of a lens attachment interface 6 (not
shown in FIGS. 2B-2C, but see FIGS. 10-11 and 13-14) to the case 2
so that a lens 22 may be coupled in stable alignment with the
miniature camera module embedded in the mobile camera device, e.g.,
an iPhone, Android or Samsung phone or other smart phone, embedded
device or camera device.
[0124] FIG. 3A illustrates an example of a device that uses an
inductive sensing lens recognition technique. The technique
involves creating eddy currents in the metal lens holder body or
attachment to the lens holder and measuring the strength of the
induced magnetic field using a tuned coil lens sensor 38 in the
connected case (not shown in FIG. 3A, but see FIGS. 1, 2B-2C and
10). The tuned coil sensor 38 is connected by a sensor connection
40 to a main PCB 42. An example tuned coil sensor 38 includes: 18
turns, 2 layers, 0.25 mm sp, 1 oz. Cu, 7 mil tr/sp, and has a fixed
target distance of .about.2 mm, and a coil that is 100% covered but
offset 8 mm, and is a 14 mm PCB coil at .about.8 .mu.H. An example
sensor connection 40 includes long coil traces on top and solid
ground plane on bottom. An example main PCB 42 includes 4 layer
PCB, coil traces on top and solid ground on layer 2. Each of
multiple lens types will produce a unique induced magnetic field
magnitude depending on the properties of the lens holder.
[0125] In the example illustrated at FIG. 3A, three lens types are
shown as FIGS. 3A(i)-3A(iii) that each have a same amount of
stainless steel, but different amounts of anodized aluminum. In
this example, the density of anodized aluminum is the same in each
of lens holders 44, 46 and 48, illustrated at FIGS. 3A(i)-3A(iii),
respectively, while lens holder 46 includes twice as much anodized
aluminum as lens holder 44 and lens holder 48 includes three times
as much anodized aluminum as lens holder 44, because lens holder 44
has a height of 10 mm, lens holder 46 20 mm, and lens holder 48 30
mm.
[0126] FIG. 3B illustrates a specific electrical circuit example of
the inductive sensing lens recognition technique of the embodiment
illustrated at FIG. 3A.
[0127] FIG. 4 illustrates an example of a device that uses a
capacitive sensing lens recognition technique. A capacitive sensing
technique is provided in this example embodiment by using the lens
body 22A as a capacitor plate and measuring the RC decay time and
frequency response when driven by the connected case. A capacitance
reference plate 48 is connected by a lens sensor connection 50 to a
main PCB 52. The plate 48, connection 50 and PCB 52 are embedded
within a case ((not shown in FIG. 4, but see FIGS. 1, 2B-2C and
10). When a lens 22 is attached to the case that includes a lens
housing 22A and lens optic 22B, the lens housing 22A and lens optic
22 function as a capacitor plate 22A and dielectric 22B,
respectively, wherein the capacitance reference plate 48 completes
the capacitive circuit element. A RC circuit includes a resistor
54. When power is applied to the RC circuit, the charge and decay
times depend on the capacitance of the lens capacitor formed by the
lens 22 and reference plate 48 which differs depending on which
lens type is attached, thereby identifying the attached lens
type.
[0128] In the example of FIG. 4, when a lens and lens housing (22)
are attached to a mounting plate 48, the capacitance formed by the
lens housing 22A and capacitance reference plate 48 changes such
that the current flowing through the resistor 54 on the main PCB 52
takes a different amount of time to charge the change in
capacitance. Multiple lenses representing different capacitance
values can be detected (presence) and differentiated (uniquely
identified) based on the time of charge and decay.
[0129] FIG. 5A illustrates an example of a device that uses
electrical connections between exposed electrodes 57 on a lens
sensor interface 58 and exposed electrodes 60 on a lens 22 or lens
holder 22A or attachment to a lens holder 22A. A direct electrical
connection technique is provided in this embodiment that utilizes
the conductive properties of the lens body 22A to complete an
electrical circuit to be measured by the connected case. In this
example wherein the lens sensor interface 58 includes four
electrodes 57, eight (8) unique combinations of connected and
non-connected electrodes 57 permit discernment by the processor 16
of the main PCB 62 of eight different lens types, as follows:
[0130] If there are no connections between lens sensor interface
electrodes 57 and lens holder electrodes 60, the PCB 62 will
measure a specific electrical quantity associated with the 000
configuration, where "0" represent no connection and "1" represents
a connection. If there are three connections, the PCB 62 will
measure a specific electrical quantity associated with the 111
configuration. An electrical circuit example is illustrated within
the main PCB 62 in FIG. 5A, including a configuration of resistors
and a defined positive reference 64, negative reference 66, and
measurement node 68. Each type of lens 22 has an electrode 60 that
contacts the negative reference 66. If the specific lens 22
includes an electrode 60 that contacts one of the three electrodes
57 that are not the negative reference 66 when the lens 22 is
attached to the case (not shown in FIG. 3A, but see FIGS. 1, 2B-2C
and 10), the PCB 62 will measure an electrical quantity unique to
the 100, 010, or 001 contact configurations depending on which of
the three locations that the contact is made. If the lens 22 has
two contacts of three the PCB 62 will measure an unique electrical
quantity corresponding to which of the 110, 101, or 011 contact
configurations where the two contacts are made. If there are three
contacts made when the lens 22 is coupled to the case, the PCB 62
will measure an electrical quantity that depends on which of the
111 contact configurations is made. In all, 8 different lens types
can be identified using the three contacts 57 that read a unique
configuration of up to four electrodes 60 for each lens type, and
the binary adder method described and illustrated in this
example.
[0131] FIG. 5A illustrates an analog method of identification where
the voltage at the measurement node is a binary sum of each
connection point present at the lens. In certain embodiments, the
analog voltage is fed to an analog to digital converter and
quantified to determine the unique lens type.
[0132] FIG. 5B schematically illustrates a digital method of
identification where each lens connection point represents a `1` or
`0`. The presence or absence of connection points at the lens forms
a unique digital binary code to determine the unique lens type.
[0133] The filter block in FIG. 5B includes a combination of
resistors and capacitors to reduce noise that may be coupled to the
system from various sources.
[0134] In the example of FIG. 5A, an electrical connection is made
between exposed conductive points on the lens body and the sensor.
Current then flows from the positive reference through each sensor
connection point back to the negative reference. The created
voltage at the measurement node will be unique to each lens type.
Multiple lenses having a different number of connection points can
be detected (presence) and differentiated (uniquely identified)
based on the voltage at the measurement node.
[0135] In the example of FIG. 5B, an electrical connection is made
between exposed conductive points on the lens body and the sensor.
Current then flows from the microprocessor pin through each sensor
connection point back to the negative reference. The created
voltage at each microprocessor pin is indicative of a connection
point on the lens. Multiple lenses having a different number of
connection points can be detected (presence) and differentiated
(uniquely identified) based on the binary combination of
connections.
[0136] FIG. 6 illustrates an example of embedded components,
including a lens sensor connection 70 and main PCB 72 of a mobile
camera device case that reads the lens type from a unique
identifier provided by an integrated circuit 74 or other readable
technique. In this embodiment, a direct electrical connection
provides a lens recognition technique by using an integrated
circuit 74 in or attached to the lens 22 that contains an
identification number that is read electrically by the PCB 72 of a
connected case. Each lens type has a different unique identifier
that is readable by the PCB 72. A circuit may be formed when a lens
22 is coupled into stable alignment with the miniature camera
module of the mobile camera device at a lens attachment interface
that is coupled with or integral with a mobile device case that is
itself coupled around the mobile device. In this embodiment, a
micro-bayonet lens interface 76 is illustrated that includes an
electrical isolation portion 78, such that a IC read circuit is
completed when the lens 22 is stably coupled to a lens attachment
interface (not shown in FIG. 6, but see FIGS. 10-11 and 13-14) upon
rotation of the lens and attachment between the micro-bayonet
interface 76 of the lens 22 and the lens attachment interface that
is coupled to or integral with the mobile device case (not shown in
FIG. 6, but see FIGS. 1, 2B-2C and 10).
[0137] In the example of FIG. 6, an integrated circuit 74
containing a unique ID is embedded in each lens. An electrical
connection is established via the micro-bayonet interface 76
allowing the main PCB 72 to read the unique value. The unique ID
read from the lens 22 allows a lens 22 to be detected (presence)
and differentiated (uniquely identified) based on the ID value.
[0138] FIG. 7 illustrates another lens recognition technique that
utilizes Near Field Communication (NFC) by using a field-powered
radio frequency (RFID) tag (80) in or attached to the lens 22 that
contains an identification number that is read by the connected
case or the phone NFC radio and passed to the processor. A NFC
Antenna 82 reads the RFID tag 80 and is connected by lens sensor
connection 84 to a NFC reader 86 of a main PCB 88, that also
includes a processor 90 and Bluetooth smart radio 92, that are
built-into a mobile device case (not shown in FIG. 6, but see FIGS.
1 and 2B-2C) that is configured such that an auxiliary lens may be
coupled thereto in stable alignment with a miniature camera module
of a mobile device.
[0139] In the example of FIG. 7, near field communication (NFC or
RFID) tag 80 containing a unique
[0140] ID is embedded in each lens 22. An NFC/RFID tag reader 86
generates a field to power the tag 80 allowing the main PCB 88 to
read the unique value stored in the NFC tag 80. The unique ID read
from the lens tag allows a lens 22 to be detected (presence) and
differentiated (uniquely identified) based on the ID value.
[0141] FIG. 8 schematically illustrates a technique for detecting
whether conforming or standardized lens has been coupled to a
mobile device case and aligned with an optical path of an embedded
camera module. In the example illustrated at FIG. 8, an electrical
spring connection is made between a spring electrode 93 and a
reference electrode 94. When a conforming or standardized lens 22,
e.g., including micro-bayonet 96 or other such lens interface that
includes a tab 98 is coupled to a lens sensor interface of a mobile
device case, the tab 98 serves to compress a spring 93 that makes
contact with a reference electrode 94 and completes an electrical
circuit to be detected by a processor 100 of a PCB 102 embedded
within a connected case. In the example of FIG. 8, when the
micro-bayonet 96 is rotated 90.degree. into place, the bayonet tab
98 pushes the spring electrode 93 into its compressed position. The
spring 93 when compressed completes a circuit that allows current
to flow from the reference electrode 94. When the micro-bayonet 98
is unrotated and removed the spring 93 relaxes and the circuit is
broken. When the current flows in the circuit, the lens 22 is
detected (presence).
[0142] FIG. 9 schematically illustrates a technique for detecting
whether conforming or standardized lens has been coupled to a
mobile device case and aligned with an optical path of an embedded
camera module, and identifying which of multiple lens types has
been attached. The lens recognition technique that is illustrated
at FIG. 9 in accordance with an example embodiment utilizes an
electrical clip 104 that connects with bayonet tab detents 112
configured uniquely to identify the lens type and the conductive
properties of the metal spring clips 104 to complete an electrical
circuit to be measured by the connected case. In the example
illustrated at FIG. 9, an electrical spring connection is made
between one of multiple spring electrode clips 103 and an
electrical connection point 104 on a lens sensor connection 106
that completes a circuit in a Main PCB 108.
[0143] In the example of FIG. 9, the micro-bayonet tabs 112 have
detents machined at distinct intervals. The absence or presence of
a detent feature is unique to each lens type. When the
micro-bayonet 110 is rotated 90.degree. into place, the bayonet tab
112 pushes features on a custom clip 103 into place such that the
absence of a detent causes the clip 103 to make contact with an
exposed electrode 104 on the sensor interface circuit 106. When the
clip 103 makes contact with the electrode 104, current then flows
from the positive reference through each clip connection point 104
back to the negative reference 118. The created voltage at the
measurement node 114 will be unique to each lens type. Multiple
lenses 22 having a different detent pattern can be detected
(presence) and differentiated (uniquely identified) based on the
voltage at the measurement node 114.
[0144] When a conforming or standardized lens 22 of a specific lens
type, e.g., including a micro-bayonet interface 110 or other such
lens interface that includes a tab 112 including detent features
that are unique to the specific lens type of the lens 22 that is
coupled to the mobile device case that includes an embedded lens
sensor connection 106 and PCB 108, the tab 98 serves to make
electrical contact with a unique combination of the spring
electrode clips 103 and completes an unique electrical circuit on
the PCB, e.g., including the resistors, the measurement node 114
and the positive reference 116 and the negative reference 118 shown
schematically in FIG. 9. An unique electrical quantity is measured
and matched by processor 120 to a specific lens type of a lens 22
that is currently connected to the mobile device case and aligned
with its integrated miniature camera module.
[0145] FIG. 10 is an exploded view of an example of a case assembly
that is configured to couple around a camera-enabled mobile phone,
such as an iPhone, or an Android or Samsung smart phone, or other
embedded device that includes an installed camera module in
accordance with certain embodiments. The case assembly of the
example embodiment of FIG. 10 includes an overmold 201 that may be
formed from polycarbonate with TPU/silicone or another material
such as any standard mobile device case material. The case assembly
of FIG. 10 further includes a lens attachment interface 202, a
mount interface overmold 203, a main PCB cover 204, a battery door
205 and battery 215, and a camera strap attachment 206.
[0146] A half-press/full-press image capture shutter button is also
illustrated in the example embodiment of FIG. 10 including a button
mechanism assembly 207, a detent spring 208 and detent spring
holder 209. Further example embodiments of the
half-press/full-press shutter button are illustrated at FIGS.
17A-28.
[0147] FIG. 10 further illustrates a custom grip plate 210, and an
inner cushion/lining 211 of an example case assembly. A white
plastic LED 212 is also illustrated at FIG. 10.
[0148] Electrical circuits 213 and 214 are illustrated at FIG. 10
schematically. Some examples of these circuits 213 and 214 have
been discussed with reference to FIGS. 1-9 as electric circuit
and/or wireless components of a PCB 12, 42, 52, 62, 72, 88, 102,
108, lens sensor connection 10, 40, 50, 61, 70, 84, 99, 106 and
lens sensor interface 8, 28, 38, 48, 58, 70, 82, 99, 103 as set
forth in several non-limiting examples.
Lens Attachment Interface
[0149] Lens attachment interface integration with a case is
provided in certain embodiments by a custom designed stamped metal
micro-bayonet interface detail co-molded into the material of the
case. In other embodiments, a custom designed stamped metal
micro-bayonet interface is adhered to the case using a mount plate
that is designed and configured to be adhered to back or inside of
phones/devices using adhesive or magnetic material.
[0150] FIGS. 11A-11C schematically illustrates examples of a lens
attachment interface co-mold in accordance with certain
embodiments. In the example of FIG. 11A, a chamfered edge 1102 is
designed to look clean from the top angle and to help guide the
lens into place for easy attachment. A molded in depression 1104
acts as an alignment dot for when attaching lens. An area 1106
covers the flex sensor PCB. Detail 1108 is meant to look clean as
if it was molded into place or is same curvature as inside case of
shell. In the example of FIG. 11B, a surface 1110 is flush with the
front of the phone case. In the example of FIG. 11C, a stamped
mount interface 1112 is visible a small amount. This feature 1112
is clear to ensure lens can attach properly. The surface 1114
matches curvature of inside of phone case, and matches iPhone 6
curvature. Mount interface 1116 is a shape of the rest of the mount
interface can be re-designed to ensure optimal co-molding design
and conforms to Apple case design specification. The material may
be polycarbonate (MT-11006) or TPU/TPE (MT-11005). The example of
FIG. 11A-11C may be co-molded into full case or is a secondary
attachment and adhered in place
[0151] FIGS. 11D-11G illustrate top, bottom, side and perspective
views of another example lens attachment interface in accordance
with certain embodiments that may be co-molded with a mobile device
case, or designed for stable coupling between the mobile device and
a firmly installed case. In the example of FIG. 11D which
schematically illustrates a top view of a bayonet interface (phone
side), bayonet tabs drop into place of phone interface side. In the
example of FIG. 11F, bayonet tabs rotate 90.degree. and interfere
with the detent of the stamped plate to create pressure and hold
the lens into place, hitting the final position of the stamped
interface which stops rotation. In the example of FIG. 11G, a
stamped stop 1120 of mount plate and stamped interface detent 1122
are schematically illustrated. FIGS. 11H-11T illustrate several
views of an auxiliary lens holder that is designed to couple with
the auxiliary lens attachment interface of FIGS. 11D-11G. In the
example of FIGS. 11H-11T, the material may be 17-4 annealed
stainless steel which may be fully hardened, and surfaces may be
matte black. FIGS. 11A-11T are described in additional detail below
with reference to example auxiliary lens embodiments.
[0152] The combination of the microbayonet tabs and the lens
attachment interface permits that microbayonet feature of an
auxiliary lens to penetrate the plane of the lens attachment
interface cavity in a first orientation and then to stably couple
the lens to the lens attachment interface and mobile device case
when rotated 90 degrees to a second orientation. The rotation need
not be 90 degrees, but may be a smaller angle between some minimum
and 90 degrees and even beyond 90 degrees to some maximum before
the tabs again line up with the interface cavity making it
detachable. The lens may be positioned onto the case with the
bayonet tabs penetrated through the lens attachment cavity, and
then may be rotated, or alternatively, translated, to overlap the
bayonet tabs with detent features of the lens attachment interface
of stably couple the auxiliary lens into position along the optical
path of the camera module of the mobile device.
[0153] FIG. 12A-12D schematically illustrates an example of a case
for coupling with a mobile phone or other embedded device in
accordance with certain embodiments. An aperture 300 in the case
illustrated at FIGS. 12B and 12D is designed to accommodate the
stable coupling of a separate lens attachment interface such as
element 202 of FIG. 10 or any of the lens attachment interfaces
illustrated schematically at FIGS. 13A-13C and 14. FIG. 12A
illustrates a cutout 302 for a half-press/full-press shutter
button, e.g., including a slight chamfer around the slot 302 on
overmolded material. In the example side view illustrated
schematically in FIG. 12A, a button access 1202 is shown designed
into overmold material, and a hole 1204 for a LED is shown with
slight chamfer around hole in overmold material. In the example
rear view shown schematically in FIG. 12B, a curvature 1206 of the
case matches a curvature of an iPhone 6. A MOMENT word mark 1208 is
schematically illustrated in FIG. 12B as being identified 0.2
mm-0.25 mm deep and polished in cavity. In the example of FIGS.
12A-12D, the shell material 1210 may be white polycarbonate, the
overmold material 1212 may be jet black TPU/silicone. In the
example of FIG. 12C, a button access 1214 designed into overmold
material is schematically illustrated.
[0154] FIG. 12D illustrates an area 303 for detail that covers a
flex PCB lens recognition sensor such as any of those described in
the examples provided at FIGS. 1-9. The detail may be molded into
the case or secondary assembled and bonded into place. The area 303
also has a stamped mount interface co-molded into. FIG. 12D also
shows a locating point 1216 for a flex PCB and a locating point
1218 for a main PCB. A locating feature 1220 is also illustrated
schematically in FIG. 12D. FIG. 12D also shows an example of a
molded guide 304 for the shutter button mechanism or another button
mechanism of the mobile device. Another molded guide 306 is shown
in FIG. 12D for a spring holder that is used to facilitate proper
tension in the spring and button assembly of the
half-press/full-press shutter button that is illustrated by the
examples of FIGS. 17A-28.
[0155] FIG. 13A-13C schematically illustrates an example of a lens
attachment interface in accordance with certain embodiments. The
lens attachment interface 320 of FIGS. 13A-13C defines a lens mount
cavity 322 that accommodates a microbayonet feature of an auxiliary
lens, and flash cavity 324 that permits a built-in flash of a
mobile device to illuminate an object to be imaged without being
blocked by the lens attachment interface 320. In this embodiment, a
narrow region 326 connects the two cavities 322 and 324 such that
the regions 322, 324 and 326 together define a single cavity having
a barbell shape with detent lens coupling features in at least one
of the circular or elliptical end regions of the cavity. In other
embodiments, two or three distinct cavity regions may be defined in
an alternative lens attachment interface, e.g., such as that
illustrated at FIGS. 11D-11G and FIG. 14.
[0156] FIGS. 13B-13C illustrate a lens attachment interface 320
having a thick end 328 and a thin end 330. The different
thicknesses of the regions 328 and 330, and the existence of the
narrow region 326, permit an auxiliary lens to be translated into
position after penetration of cavities 324 and 326 at the thin end
330 to the thick end 328 before or after rotation of the auxiliary
lens into stable coupling with the lens attachment interface 320
over the cavity 322 that is approximately centered on the optical
path of the camera module of the mobile device. In the example of
FIGS. 13A-13C, the thickness of the plate 320 may be 30 gauge, and
the material may be 17-4 stainless steel, fully hardened, and the
color may be PVD coating black, then electrochemical coloring. The
plate 320 may be configured with deburr and break edges up to 0.2
and without sharp edges.
[0157] FIG. 14 schematically illustrates a cutaway view of an
exemplary camera-enabled mobile device case 402 and lens attachment
interface 406 in accordance certain embodiments. A lens attachment
interface 406 fits stably into a pocket in the case 402 in this
embodiment. The interface 406 may alternatively be molded into the
case 402. The interface 406 includes an elongated shape that
conforms approximately in length with the length of the short side
of a rectangular mobile device such as a smartphone made by Apple,
Samsung, LG other Android manufacturer.
[0158] The interface 406 includes aperture 410 and aperture 412.
Aperture 410 is sufficiently elongated that a slightly smaller
elongated microbayonet feature of an auxiliary lens may penetrate
the aperture 410 when the long axes are aligned, and serves to
stably couple the auxiliary lens to the case 402 after rotation by
90 degrees more or less. The auxiliary lens includes magnets or
electrical contacts or an IC or other readable lens type identifier
such that the lens sensor 408 (see, e.g., FIGS. 1-9) can perform a
measurement to be analyzed by a processor 410 on a connected
printed circuit board 412 to determine the lens type and custom
image setting, processing and editing processes and applications to
be used in accordance with the determined lens type.
[0159] FIG. 15G illustrates the lens attachment interface 406 of
the example of FIG. 14 may include a metal plate 420 such that an
attached magnet may hold the interface 406 in place at the long end
of an example mobile device (e.g., iPhone) where the miniature
camera module is located.
[0160] FIGS. 15H-15K schematically illustrate a case for picture
takers that is handable, mountable, connected and the new shooter
with Bluetooth and proprietary lens sensor technology. FIG. 15H
schematically illustrates a tripod 1230 mountable for long exposure
time lapse function on OS8. FIG. 15I schematically illustrates talk
1232 between a lens and a case. FIG. 15J schematically illustrates
a quick release compatible strap 1234. FIG. 15K schematically
illustrates an integrated lens mount 1236 and a camera style grip
1238.
[0161] FIGS. 16A-16D schematically illustrate an example of a main
PCB cover portion of a case in accordance with certain embodiments.
The material may be polycarbonate. The color may be jet black. The
finish may be mold tech finish number MT-11006.
[0162] In certain embodiments, Bluetooth control of certain
features is provided, including shutter control, focus, exposure,
lighting, power, and other pre-capture settings and post-capture
editing control that have been described elsewhere herein. In
addition, certain embodiments include features described at US
published application no. US2012/0282977, which is incorporated by
reference.
Half-Press/Full-Press Shutter Button
[0163] A half-press/full-press shutter button in accordance with
certain embodiments includes half-press touch-screen functionality.
That is, while the shutter button is held in half-press mode, touch
screen control functions are accessible and/or burst mode and/or
video may be enabled. Half-press also enables certain pre-capture
features such as lighting and exposure adjustment, flash options,
auto-focus, face detection/tracking focus or manual focus
selection, and image size, scene mode, ISO, white balance, color
effect, timer, geotagging and shutter sound options, as well as
normal, high dynamic range, panorama, continuous shot and portrait
options, and time catch shot selection, as well as a voice shutter
option. Any subset of these features may be enabled while the
shutter button is being held in half-press mode. FIGS. 17A-28
illustrate several example half-press/full-press button
embodiments, including various mechanical and electrical
features.
[0164] FIGS. 17A-28 schematically illustrate example embodiments of
a custom designed mechanism to enable actuation of an
electro-mechanical interface for adjusting pre-capture settings and
capturing digital images. Each implementation has a custom design
to actuate two different switches with one tactile button (button);
one for half press (e.g., focus and expose image and other
pre-capture settings, see above) and the second for full press
(capture image). The logical functions of the two switches are
defined in software and thus are not tied specifically to focus,
expose, other pre-capture settings, and image capture. These may be
referred to as full press and half press.
[0165] In certain embodiments, a stamped metal spring is used with
a case having a button that actuates half press and full press
switches on a PCB. There is a metal stamped detail adhered to the
button. In this embodiment a HDPE detail is used to decrease
friction of the button mechanism. In addition, this embodiment may
include a stamped metal spring and stamped spring holder. FIG. 17A
illustrates a metallic component before it is bent to form a detent
spring for a shutter button for a camera-enabled mobile device case
in accordance with certain embodiments.
[0166] FIGS. 17B-17F illustrate a detent spring for a shutter
button for a camera-enabled mobile device case in accordance with
certain embodiments. In the example of FIGS. 17A-17F, the
dimensions are in millimeters. The material may be 0.8 mm thick
beryllium-copper alloy 25, fully hardened slowly to ensure no
distortion.
[0167] FIGS. 18A-18F illustrate a detent spring holder for use with
the detent spring of FIGS. 17B-17F for a shutter button for a
camera-enabled mobile device case in accordance with certain
embodiments. In the example of FIGS. 18A-18F, the dimensions are in
millimeters. The color, material and finish may be black,
polycarbonate/delrin and smooth surface with no uneven machine
marks, respectively.
[0168] FIGS. 19A-19D schematically illustrate a shutter button
mechanism assembly for a camera-enabled mobile device case in
accordance with certain embodiments. FIG. 19A schematically
illustrates an exploded perspective view including a mechanism
attaching button and spring 1242, a shutter button 1244 and a
friction slider for button mechanism 1246. The prongs of the
mechanism attaching button and spring 1242 are adhered into slots
of friction slider for button mechanism 1246. The shutter button
1244 fits around the mechanism attaching button and spring 1242 and
is adhered into place. In the example of FIG. 19C, the button 1244
is not on the same plane as the liner since the liner is meant to
decrease friction during button actuation.
[0169] FIGS. 20A-20G schematically illustrate a shutter button for
a camera-enabled mobile device case in accordance with certain
embodiments. The material may be polycarbonate. The color may be
jet black. The finish may be polished/gloss from front surface to
dashed line called out on FIGS. 20A-20G.
[0170] FIGS. 21A-21C schematically illustrate a mechanism attaching
shutter button and spring for a camera-enabled mobile device case
in accordance with certain embodiments. The dimensions are in
millimeters. The material may be stainless steel.
[0171] FIGS. 22A-22C schematically illustrate a friction slider for
a shutter button mechanism for a camera-enabled mobile device case
in accordance with certain embodiments. The dimensions are in
millimeters. The material may be cross-linked polyethylene. The
color may be jet black. The finish detail is meant to act as
anti-friction liner
[0172] FIGS. 23-28 schematically illustrate examples of additional
alternative shutter button mechanisms for camera-enabled mobile
device cases in accordance with certain embodiments.
[0173] FIG. 23 schematically illustrates another

with a second conductive elastomer contact that will close a
circuit and actuate the full press function.
Smart Case System for Mobile Photography
[0179] A smart case system for mobile photography is provided
herein, including a case, an auxiliary lens and a software app. The
case may include features described elsewhere herein including lens
recognition electronics, a half-press/full-press shutter button
feature, a lens attachment interface that permits stable mechanical
coupling of an auxiliary lens to a mobile device that uses
mechanical features to precisely align the auxiliary lens with an
on-board camera module of the device. In addition, attachment
locations are provided in certain embodiments for a wearable strap
and tripod attachment.
[0180] A recognizable auxiliary lens attachment is also provided
herein. The auxiliary lens attachment can be selected from multiple
lens attachments that may be used to provide enhanced photography
in different ways. For example, one auxiliary lens attachment may
provide a wide field of view, while another may provide a more
distant or closer focus plane than the on-board camera module of
the mobile device can provide. An auxiliary lens attachment may be
provided that includes a zoom feature or an autofocus or manual
focus feature including one or more movable optics (using piezo,
MEMS, or VCM, e.g.,) within a fixed lens barrel or coupled to a
fixed lens barrel. The auxiliary lens attachment may include a
single lens or a stack of two or more lenses.
[0181] Auxiliary lens attachments are provided in certain
embodiments that are recognizable by a mobile device case. The
auxiliary lenses and mobile device case are constructed with custom
or standardized complementary lens recognition features. Several
embodiments have been illustrated in examples elsewhere herein.
[0182] A software application is also provided herein which
controls a processor on a PCB embedded within a mobile device case
and receives data from a lens attachment interface that couples
mechanically, electrically and/or wirelessly with an auxiliary lens
attachment to provide a signal to be processed by the processor,
such that based on this data, auxiliary lens specific
user-selectable functions may be used to improve the mobile
photography experience. In addition, certain automatic settings
that depend on auxiliary lens type are performed in certain
embodiments that enhance captured images by pre-capture settings or
post-capture edits.
[0183] FIGS. 29-33 illustrate screen shots of graphics generated
based on programming and data gathered by components of a
camera-enabled mobile device case in accordance with certain
embodiments. For example, FIG. 29 illustrates wide angle lens
recognition, and FIGS. 30-31 illustrate touch screen lighting and
exposure adjustment while the shutter button illustrated by the
examples illustrated at FIGS. 10 and 17A-28 is half-pressed as in
FIG. 32. FIG. 33 illustrates a full pressed shutter button for
image capture in accordance with certain embodiments. Certain
remote control feature may also be included, e.g., as set forth at
WO2012096433, which is incorporated by reference.
Auxiliary Lens for Mobile Photography
[0184] Traditional mobile photo lenses provide ordinary picture
quality for ordinary use. An advantageous auxiliary lens can be
attached in accordance with various embodiments described by way of
example herein to enhance the mobile photography experience. In
certain embodiments, an auxiliary lens includes smart lens
functionality.
[0185] Referring again to the example illustrated schematically at
FIG. 1, a Bluetooth module may be embedded inside the lens 22. The
main PCB illustrated schematically in FIG. 1 includes a Bluetooth
smart radio 18. The lens 22 with Bluetooth module is advantageously
configured as a smart lens capable of talking wirelessly to the
case 2, e.g., to provide associated technical data that enhance the
mobile photography experience. The lens 22 with Bluetooth module
may also be configured to talk wirelessly to the mobile device
and/or an external device.
[0186] In certain embodiments, an auxiliary lens 22 may include a
microbayonet mount. The microbayonet mount may include a thin
element that extends in the plane approximately normal to the
optical path of the lens 22. The shape of the microbayonet mount
may be selected in accordance with the shape of the cavity defined
in the lens attachment interface 6 that is coupled to or integral
with the case 2. Examples of lens attachment interfaces in
accordance with certain embodiments are provided in FIG. 10 as
element 202, and in FIGS. 11A-11G, 13A-13C, and 14.
[0187] The shape of the cavity defined in the lens attachment
interface may include any regular or irregular polygon or
combination of curved and straight edges that permits the
microbayonet element of the auxiliary lens (see, e.g., FIG. 8,
elements 96 and 98 and FIG. 9, elements 110 and 112, and FIGS.
11H-11T) to penetrate the plane of the cavity defined in the lens
attachment interface 6, and then to stably couple the lens 22 to
the lens attachment interface 6 upon rotation or translation of the
penetrated microbayonet element of the lens 22.
[0188] In another example, the microbayonet element may have an
elliptical or rectangular shape. A corresponding lens attachment
interface cavity may have a slightly larger elliptical or
rectangular shape. The sizes and shapes of these two features are
such that the microbayonet can penetrate the cavity to attach or
detach when the elliptical or rectangular shapes are aligned, while
the microbayonet cannot cross the plane of the cavity when the
elliptical or rectangular shapes are relatively rotated by an
angular amount within a range between some minimum angle and 90
degrees. In general, the shapes can be various, including an "x"
shape, wherein the rotation by 45 degrees would be optimal to
secure the attachment.
[0189] The microbayonets, 96, 98 and 110, 112 of FIGS. 8 and 9,
respectively, include a rectangular shape overlapping a circular
shape at its center, wherein the long edge of the rectangle is
greater than the diameter of the circle and the short edge of the
rectangle is lesser than the diameter of the circle. The
microbayonets 96, 98 and 110, 112 of FIGS. 8 and 9, respectively,
are hollow, or alternatively transparent with antireflection
coatings, in the circular region which serves as an aperture that
permits light to travel along the optical path towards the image
sensor of the mobile device. Thus, an auxiliary lens may have a
microbayonet feature that has tabs of any of a variety of oblong
shapes that protrude from a hollow or transparent center which
accommodates the optical path of the camera.
[0190] In several embodiments illustrated at FIGS. 10 and 11A-11C,
the lens attachment interface has a barbell shape that includes a
pair of circular regions connected by a thin middle region. One of
the circular regions of the lens attachment interface 6 may serve
both to couple with the lens 22 in accordance with the microbayonet
embodiment and as an aperture to accommodate light traveling along
the optical path from the object to be imaged through the auxiliary
lens, the aperture, the built-in lens of the camera module and
ultimate to the image sensor. The other circular region defined in
the lens attachment interface 6, or mount plate as it may also be
referred to, provides room for a microphone and/or flash that are
provided on the back of an iPhone, Android, Samsung or other
camera-enabled smartphone device.
[0191] FIGS. 11D-11G schematically illustrate another example
embodiment of a lens attachment interface 6 or mount plate, e.g., a
microbayonent mount, that is embedded into the lens case 2 to
provide secure attachment of an auxiliary lens 22 to the case 2
that is itself stably coupled around a mobile camera-enabled
device. FIG. 11D schematically illustrates a lens attachment
interface 220 that is integral with or stably attachable to a
mobile phone case. The lens attachment interface 220 or mount plate
220 of FIG. 11D defines a first cavity 222 and a second cavity 224.
The first cavity 222 accommodates both the coupling of an auxiliary
lens 22 having a microbayonet feature (see FIGS. 8 and 9) and an
unencumbered optical path of the camera module. The second cavity
224 accommodates a flash and/or microphone that may be built into
the mobile device.
[0192] The first and second cavities 222 and 224 can be shaped and
positioned to accommodate the locations of the image sensor and
flash/microphone features wherever they may be placed on the mobile
device. For example, embodiments provided herein at FIGS. 10,
11A-11G and 12A-12D, among others, illustrate features that match
iPhone features. However, LG Android devices typically have the
image sensor and flash centered at one long end of the device and a
microphone nearer the bottom of the device, while a Samsung device
typically has the image sensor and flash approximately centered on
the device. Regardless of where the image sensor and flash are
located, the features of the described embodiments can be modified
to accommodate the location, size and shape of the camera module of
a particular device without significantly changing the general
characteristics and advantages of the functional case, auxiliary
lens and lens attachment interface coupling feature,
half-press/full-press shutter button which may also vary in
location, size and shape depending on the mobile device with which
the case is coupled around, and the functional software
applications set forth in embodiments described herein.
[0193] A macro auxiliary lens may include a 10.times. to 20.times.
macro lens that enables close-focus high resolution mobile
photography. Other auxiliary lenses may include a super wide angle
auxiliary lens, a fisheye auxiliary lens, a zooming auxiliary lens
and/or a lens described in US2014/0071547, which is incorporated by
reference.
[0194] FIGS. 11H-11T schematically illustrate examples of an
auxiliary lens holder in accordance with certain embodiments that
is particularly suited for coupling at a bayonet lend attachment
interface as described with reference to FIGS. 11A-11G.
Functional Features of Smart Case For Mobile Photography
[0195] A smart in accordance with certain embodiments includes
several functional features. Enhanced lighting performance may be
provided by, e.g., one or more white LEDs or other light sources
embedded into the smart case to illuminate an object or a scene to
be imaged. The ability to created optimum illumination geometries
for mobile photography beyond the simple mobile flash is an
advantageous feature of a smart case in accordance with certain
embodiments.
[0196] Attachment of an auxiliary lens and/or other optical,
electrical, wireless communication and mechanical features provide
many advantages. For example, the case may include a Bluetooth
radio that can be coupled in communication with various third party
accessories including display devices, remote control devices and
other processor-based devices. The design of the smart case enables
the attachment of additional accessories that enhance the mobile
photography experience.
[0197] Stabilization is also provided. The embodiments described
herein detail a smart case with the ability to provide image
stabilization, particularly for macro and extreme telephoto lenses,
that may be attached stably to a mobile device using an
advantageous case and lens attachment interface as described with
reference to several examples herein.
[0198] Additional power is also provided in certain embodiments.
FIGS. 34A-34E schematically illustrate a battery door for a
camera-enabled mobile device case in accordance with certain
embodiments, and FIG. 41 illustrates a coin cell battery. In the
example of FIGS. 34A-34E, the dimensions are in millimeters. The
material may be TPU/TPE shore 60-75 A, and the hardness allows
living hinge to work and hold battery in place. The color may be
jet black and the finish may be mold tech finish no. 11005. The
example of FIGS. 34A-34E includes a 0.5-1.0 mm thick foam layer to
help push battery against battery contact. The additional power
provided by a battery installed in the case may be used to power
the processor and PCB and lens sensor of the case, and in some
embodiments to power the mobile device itself when, e.g., the
mobile device is low on battery power or is out of battery power.
Additional Memory is also provided in certain embodiments as a
component included PCB of the case.
[0199] A customizable camera grip may be molded directly into a
smart case in accordance with certain embodiments. For example, a
smart case in accordance with certain embodiments allows for
changing a grip face plate material to many custom options. This
enables one-handed photography, and is ergonomically advantageous
feature for many image capture purposes including capturing
"selfies" when a one handed grip provides the flexibility of
selectably greater distances and angles for image capture, and is
particularly advantageous for pictures of two or more persons who
wish to have one arm around another person or simply be close to
another person without an out-stretched arm inhibiting that
closeness.
[0200] FIGS. 36A-36D schematically illustrate a custom grip case
for a camera-enabled mobile device case in accordance with certain
embodiments. The dimensions are in millimeters. The material of the
replaceable custom grip plate may include leather, cork, canvas,
metal, wood, plastic or rubber.
[0201] FIGS. 37A-37C schematically illustrate an inner
cushion/lining of a camera-enabled mobile device case in accordance
with certain embodiments. The dimensions are in millimeters and the
material of the inner lining may include microfiber material, cork,
felt or another fabric/textile.
[0202] FIGS. 38A-38G schematically illustrate a camera-enabled
mobile device case configured to couple with a lens in accordance
with certain embodiments. Various ergonomic alternatives are
illustrated including a recess for auxiliary lens attachment, a
grip feature that is particularly advantageous for one-handed
photography that is preferred for capturing selfies. In the example
of FIGS. 38A-38G, a case is schematically illustrated with
components 1252 stacked on the camera side while the other side
balances with the grip 1254. A recess 1256 for a lens 1258 is
schematically illustrated in FIG. 38E that allows for better
integration. A grip texture 1260 is also schematically
illustrated.
[0203] FIGS. 39A-39C schematically illustrate a camera-enabled
mobile device case configured to couple with a lens in accordance
with certain embodiments. The example of FIGS. 39A-39C
schematically illustrates in perspective, front and side views,
respectively, mass configurations of a case battery board. FIG. 38A
schematically illustrates locations for a battery 1262 and
significant mass 1263, and a sensor coil 1264 and a camera and
mount assembly 1266. In certain embodiments, components such as a
battery and perhaps one or more other heavy components are arranged
at the grip end of the smart case which perhaps ease of handling
for one-handed picture taking. This feature permit ease of handling
by reducing the torque that a single-handed camera grip has to
counter to stabilize the camera against gravity, e.g., when taking
a selfie. A difference in torque can be very large between mounting
case components on the camera module end rather than on the grip
end. Components mounted on the grip end may exert virtually no
torque because the moment arm may be reduced to zero or nearly zero
or even negative if the grip is actually closer to the camera
module and attached auxiliary lens than the heavy components that
are arranged at the very opposite end of the case. This balancing
of the weight of components in the case with the weight of the
attached auxiliary lens and lens attachment interface can provide
an enhanced one-handed picture taking experience.
Camera Strap Attachment
[0204] FIGS. 15I and 35A-35E schematically illustrate a camera
strap attachment for a camera-enabled mobile device case in
accordance with certain embodiments. In the example of FIGS.
35A-35E the dimensions are in millimeters and the material may be
aluminum 6061. Color and finish may include matte black anodize,
matte silver anodize, polished black anodize and/or polished silver
anodize. Sharp edges are broken and machined chamfer where called
out on drawings. Dual attachment to a smart case enables use of
traditional camera straps. This can be achieved using a metal or
hard plastic strap attachment adhered to the case in final assembly
or using a metal or hard plastic strap attachment co-molded into
the case in alternative embodiments or as set forth at
US2006/0124676, which is incorporated by reference.
Lens Cap
[0205] A custom lens cap is provided that works with auxiliary
lenses on several types, shapes and sizes. In certain embodiments,
a magnet is built-in to allow a lens cap to stick to the metal lens
holder material. A magnetic material such as a metal or magnet may
be assembled or molded into the case to allow a place for a removed
lens cap to rest when the lens cap is not being used to cover the
lens, e.g., when an image is being taken using the auxiliary
lens.
[0206] FIGS. 15A-15K schematically illustrate certain mobile device
cases and additional case features and accessories in accordance
with certain embodiments. A tripod attachment is illustrated that
includes a custom tripod attachment that is attachable and
detachable and allows the mobile device case to be used on standard
tripods with 1/4-20 threaded insert. A magnet is built into the
tripod attachment in certain embodiments that magnetically attaches
and aligns the tripod attachment to metal built into case. A press
fit attachment may be used in certain embodiments that creates an
interference interface over an edge of the case to hold it tightly
in place.
Capacitive Touch Slider For Image Control
[0207] FIGS. 40-42 schematically illustrate a capacitive touch
slider for a camera-enabled mobile phone device case in accordance
with certain embodiments. These Figures relate to a capacitive
touch slider feature. The board that is shown rotated in the FIGS.
40-42 is at the opposite end of the phone from where the lens is.
This feature is particularly advantageous for a picture taker who
is using one hand to adjust precapture settings and to capture the
picture, such as when a selfie is being captured, especially when
two or more persons are included in the scene.
[0208] A capacitive touch slider is provided in certain embodiments
on an ergonomic camera grip that allows via embedded firmware and
application software to control image exposure, contrast, aperture,
ISO, shutter speed, focus and/or image capture. The combination of
the ergonomic camera grip with balanced components for reduced
torque and the capacitive touch slider feature facilitate
precapture setting adjustment while the mobile device with or
without auxiliary lens attachment is balanced in position to
capture a photo, particularly a selfie or overhead image or an
image otherwise difficult to capture with two hands on the
camera.
[0209] The capacitive slider in accordance with certain embodiments
is designed to reject phone metal and antenna capacitive, radio
frequency and magnetic field effects. The capacitive slider is
mounted in accordance with certain embodiments at an ergonomic
angle to ease use with one hand and finger. In use in one example,
the capacitive slider may be operated by sliding a finger along the
surface to change or select from a menu of software defined
functions, while tapping the surface with the same finger may
actuate a software defined function that is selected, and/or double
tapping the surface may actuates a software defined function. The
single tap may serve a similar role as a half-press of the shutter
button described above, i.e., to adjust pre-capture settings before
taking a picture, while the double tap may serve a similar role as
a full-press of the shutter button described above, i.e., to
capture the image.
