Description
RELATED APPLICATION
[0001] This application claims priority under 35 U.S.C. .sctn.119
based on U.S. Provisional Patent Application No. 60/892,598, filed
Mar. 2, 2007, the disclosure of which is incorporated by reference
herein in its entirety.
TECHNICAL FIELD OF THE INVENTION
[0002] The present invention relates to the field of image
capturing units in portable electronic devices. The present
invention is more particularly directed towards a method and
computer program product for remotely controlling a first image
capturing unit of a portable electronic device as well as to such a
portable electronic device.
DESCRIPTION OF RELATED ART
[0003] Cameras and other image capturing units have become smaller
and smaller and are nowadays often present in portable electronic
devices like cellular phones.
[0004] It would however be of interest to remotely control such an
image capturing unit in such a device. One reason for this is that
when, for instance, the image may get blurred because the device is
slightly shaken as the user presses a button to activate the image
taking.
[0005] Remote control devices for cameras exist. In for instance,
U.S. Pat. No. 6,400,903, there is described the remote control of a
camera from a computer. Here the computer sends commands to the
camera and receives images from the camera. It is also possible to
control different functions relating to the camera such as zoom,
position on a tripod etc. However, these devices are complicated,
involve an increase cost and often need to be connected to the
camera, which involves a certain effort by the user. They may also
be lost.
[0006] It is furthermore often desirable to hold the camera in the
hand in order to allow a high flexibility in selecting scenes that
are to be captured by a user. To obtain a good image quality both
hands may need to be used. This is hard to combine with an
additional remote control device.
[0007] It would therefore be of interest to provide remote control
of a camera in a portable electronic device that can be performed
without any additional devices, but only using the capabilities of
the portable electronic device.
[0008] There is thus a need for an improved remote control of an
image capturing unit in a portable electronic device.

DETAILED DESCRIPTION OF EMBODIMENTS
[0043] The present invention relates to a portable electronic
device that is provided with a first and a second image capturing
unit.
[0044] As described herein, a portable electronic device, may
optically detect and track an object (such as a user's face) via an
image capturing unit in the portable electronic device and detect
changes in the object. These changes may then be used to control
another image capturing unit in the portable electronic device.
[0045] Many advantages can be obtained through the techniques
described herein. For example, it is possible to remotely control
the first image capturing unit through only changing an object, for
instance through blinking of eyes. There is no need for any
additional remote control device. Due to the increasingly lighter
weights of portable electronic devices, pressing a capture button
to capture an image can move the device slightly and cause blurring
of the image. Through allowing the image to be captured without
pressing a button, a much improved image quality can be obtained.
The remote control furthermore allows a user to hold the portable
electronic device with both hands and thus increases freedom in
selecting scenes together with a reasonable mechanical stability
may be provided. According to the present invention also the time
it takes to capture an image is reduced. This allows a user to
react to an event much faster than he/she can do by pressing a
button. Consequently, the user would have a better chance of
capturing the exact moment he/she wants. Since the units necessary
for controlling an image capturing unit already exist in many
portable electronic devices, the only additional functionality
needed may be provided as software. This means that the present
invention may be produced at low additional costs.
[0046] In FIG. 1 there is shown a front view of a portable
electronic device 10 in the form of a cellular phone and in FIG. 2
there is shown a side view of the phone 10 when being used by a
user. In FIG. 2 only the face 22 of the user, particularly
including eye 24 of the user, will be shown. Phone 10 may include a
user output unit in the form of a display 12 on a front side, in
which there is shown an indicator 18. The purpose of this indicator
will be described in more detail later. Here it is sufficient to
say that the indicator may typically be provided as a light of a
certain colour. For this reason the user output unit used for the
indicator may as an alternative be provided separately from the
display 12, for instance in the form of a LED (Light Emitting
Diode). It is also possible to provide a sound indication through
the use of a speaker.
[0047] Phone 10 may also include a set of user input units in the
form of a number of keys on a keypad 14 on the front side. There is
also a further user input unit in the form of a special button 15
provided on a side of the phone 10. This button 15 may have a first
extended position, a second half-way depressed position and a third
fully depressed position in which the actuating surface of the
button 15 is aligned with the side of the phone 10 on which the
button is provided. It should be realised that other user input
units may be used in the present invention, such as a a touch
screen or even a microphone. On the front side of the phone 10
there is also provided a video image capturing unit 16 in the form
of a video camera. This is normally used by the user in video phone
sessions with other people. It can of course also be used for
filming video. On the back side of the phone 10 there is
furthermore provided a still image capturing unit 20 in the form of
a digital camera. This camera can be used to capture still images
of different scenes. One such scene 26 is shown in FIG. 2 and
includes a tree. The still image capturing unit is here an example
of a first image capturing unit, while the video image capturing
unit is an example of a second image capturing unit that is
involved in controlling the first image capturing unit.
[0048] A cellular phone is just one example of a portable
electronic device with an ability to communicate. The invention is
in no way limited to cellular phones, but can be applied on other
types of devices like portable communication devices, for instance
a smartphone and a communicator or other portable electronic
devices like a lap top computer, a palm top computer or an
electronic organizer.
[0049] FIG. 3 shows a block schematic of the different units in the
phone 10 that are used in relation to the present invention. The
phone 10 includes the user input units 14 and 15, i.e. keypad 14
and button 15, the user output unit, i.e. display 12, video image
capturing unit 16 and still image capturing unit 20. The image
capturing units 16 and 20 may both typically include lenses
connected to digital image receiving units, which convert projected
images into digital images. Such a digital image receiving unit may
include a CCD (Charge-Coupled Device) unit. The video image
capturing unit may also include a video coding unit that codes such
images into video data, for instance according to the MPEG (Moving
Picture Expert Group) format. All the above described units are
connected to an image capturing control unit 28, which controls the
functionality of the phone 10 according to the present invention.
The two image capturing units 16 and 20 are also connected to the
display 12. It should here be realised that the phone normally
includes several more units and functions. However, these have here
been omitted in order to better focus on the present invention.
[0050] The functioning of the invention will now be described with
reference being made to the above described FIG. 1-3 as well as to
FIG. 4, which shows a flow chart of a number of exemplary
operations carried out in phone 10.
[0051] Concepts described herein are directed towards detecting and
tracking an object via the video capturing unit 16 and detecting
changes in an area of the object. These changes may then used for
controlling the still image capturing unit 20. In the following
description this object is head 22 of the user in an area 24 where
the eyes are located. It should however be realised that the
invention is in no way limited to being applied on the eyes or even
the head of a user, but may be applied to any object or area of the
user.
[0052] A remote control mode for the still image capturing unit 20
may be provided. This mode may be entered through the user making a
suitable selection in a menu system of the phone or through
pressing a dedicated button associated with this remote control
mode. However it is also possible that this mode is the only mode
of operation for the still image capturing unit 20. Therefore the
mode may also be entered as soon as a camera functionality is
selected, for instance through removing a lens protection device
from the still image capturing unit 20. The method may thus start
by the remote control mode being entered, step 30. This mode may be
initiated by the user using, for example, keypad 14. The image
capturing control unit 28 may then activates the video image
capturing unit 16 in order to provide image data of a field of view
covered by the video image capturing unit 16. The user here may
look at the video image capturing unit so that his face 22 and
details of the face such as nose, lips and eyes 24 can be
registered. The image capturing control unit 28 may include face
recognition functionality, which optically detects and tracks the
face, step 32, from image data registered by the video image
capturing unit 16. This may be performed by, for example,
segmenting the registered image, for instance according to various
fields of colour and junctions between such fields of different
colour, detecting that one or more such segments make up a face and
then tracking the face, i.e. following the movement of the face.
When the face has been identified and tracked, step 32, this may be
indicated to the user, step 34. This is done through the image
capturing control unit 28 controlling the display 12 to activate
the indicator 18, for instance through using a certain colour. In
this way the user is informed that he/she may now perform remote
control of the still image capturing unit 20. Thereafter the image
capturing control unit 28 orders the still image capturing unit 20
to present the scene 26 on the display 12 in a view-finder mode of
operation and awaits instructions from the user to activate remote
control.
[0053] In case there is no such instruction, step 36, the image
capturing control unit 28 then investigates if the remote control
mode is to be ended, step 38, which may be the case if the user has
not performed any actions within a certain time limit or if the
user has decided to exit the remote camera mode through the
activation of a button or key on the phone. If the mode is to be
ended, then the image capturing control unit 28 exits the mode,
step 40, and otherwise returns and waits for an instruction.
[0054] An instruction may be received through the user moving the
button 15 on the phone 10 from the first position to the second
half-way depressed position. Here a movement of the button 15 to
the third position might lead to a capturing of an image by the
still image capturing unit 20 in normal fashion. When an
instruction is received, step 36, the image capturing control unit
28 controls the still image capturing unit 20 to focus on the scene
26, step 42. This may be performed through the still image
capturing unit 20 auto-focusing on an element in scene 26, such as
the tree. Thereafter, the face recognition function of the image
capturing control unit 28 observes changes in at least one area of
the tracked and detected face 22 of the user and controls the still
image capturing unit 20 based on these changes. In the embodiment
described here this area 24 is the area of the eyes of the
user.
[0055] The face recognition function may detect predetermined
movements of the user in area 24, such as blinking by the user. If
the user now blinks with only his left eye, step 44, the image
capturing control unit 28 orders the still image capturing unit 20
to zoom in on scene 26, step 46, again perform auto-focusing, step
42, and then continue to observe changes in the eye area 24 of the
face 22. In the situation in which the left eye is not blinked
alone, step 44, the image capturing control unit 28 determines if
only the right eye is blinked, step 48. If this is the case, the
image capturing control unit 28 controls the still image capturing
unit 20 to zoom out in the scene 26, step 50, again perform
auto-focusing, step 42, and then continue to observe changes in the
eye area 24 of the face 22. In case the right eye was not blinked
alone, step 48, the image capturing control unit 28 investigates if
both eyes were blinked simultaneously, step 52. If they were, the
image capturing control unit 28 orders the still image capturing
unit 20 to capture a still image, step 54, and thereafter continue
to observe changes in the eye area 24 of the face 22. In case no
eyes were blinked, step 52, the image capturing control unit 28
determines if the remote control mode is to be ended, step 56,
which may be the case if the user has not performed any blinking
within a certain time or if the user has decided to exit the remote
camera mode through the actuation of the button 15. This may be
achieved through completely releasing the button 15 so that it
moves back to the first position, which would thus turn off remote
control and thus allows the user to blink as normal. If the mode is
to be ended, then the image capturing control unit 28 exits the
mode, step 58.
[0056] In the manner described above it is possible to remotely
control the still image capturing unit through only blinking of the
eyes. Due to the increasingly lighter weights of mobile camera
phones, pressing a capture button to take a picture can move the
phone slightly and cause blurring of the image. Through allowing
the picture to be taken without pressing a button, a much improved
quality of picture can be obtained. The remote control does
furthermore allow a user to hold the portable electronic device
with both hands without using a special remote control device and
thus a great freedom in selecting scenes together with a reasonable
mechanical stability may be provided. Also, according to the
present invention, the time it takes to take a picture is reduced.
This allows the user to react to an event by much faster than
he/she can do by pressing a button. Consequently, the user would
have a better chance of capturing the exact moment he/she
wants.
[0057] Since the different capturing units, display, keys and
buttons already exist in many portable electronic devices, the only
additional functionality needed may be provided as software. This
means that the present invention may be produced at low additional

[0058] There are a number of variations that can be made to the
present invention apart from the ones already mentioned. It is
possible that only one eye is used for controlling the still image
capturing unit, where a blinking of the eye would then only capture
a still image. A blinking of only the left eye may of course be
used for zooming out and the right eye for zooming in. It is also
possible to have blinking control of other functions of the still
image capturing device. It is also possible that other areas of the
face are used for controlling the still image capturing unit either
instead of or in addition to the eyes, for instance the mouth. It
is furthermore possible that it is another object than the head of
the user that is used, for instance an arm or a hand of the user.
The present invention is therefore directed towards detecting and
tracking an object via the video capturing unit and detecting
changes in an area of that object, which changes are then used for
controlling the still image capturing unit. The invention is
furthermore not limited to the above described positions of the
button used or even to the use of a dedicated button for giving the
instruction to activate remote control and leaving the remote
control mode. Other ways may be provided for this purpose, for
instance using the keypad or even using voice-recognition. Thus any
tactile or audio input unit may be used for providing the
instruction and leaving the remote control mode.
[0059] The capturing control unit in the phone is normally provided
in the form of one or more processors together with a program
memory store containing program code for performing the functions
of this capturing control unit. This program code can also be
provided on a computer program product, like a CD ROM disc, a
memory stick or another suitable data carrier, which performs the
invention when being loaded into the device. One such medium is
schematically shown in FIG. 5, which shows a CD ROM disc 60, on
which the program code for the phone may be provided. The program
code may furthermore be provided on an external server and
downloaded from there into the phone.
[0060] It should furthermore be known that the video image
capturing unit may have still image capturing ability and the still
image capturing unit may have video image capturing ability. The
remote control described above is therefore not limited to still
images but may also be applied when capturing video. It is
furthermore not necessary to present the scene to the user.
[0061] Therefore the present invention is only to be limited by the
following claims.
