Description
BACKGROUND OF THE INVENTION
[0001] 1. Technical Field
[0002] The present invention relates to a lighting system for
computer web cameras. More specifically, the present invention
relates to methods and apparatus for a universal lighting system in
combination with a light diffuser lens for use with a flat screen
monitor fitted with a web camera for enhancing and clarifying,
while reducing distortion flaws, of an image of a computer subject
generated by the web camera for transmission over a worldwide
communication network.
[0003] 2. Background Art
[0004] Laptop computers and desk top computers for use on the
networking infrastructure known as the Internet can include a web
camera for capturing and transmitting the visual image of the
person operating the computer over the network. These computer
camera systems (typically referred to as web cam systems) for use
over the Internet network are popular particularly when utilized by
social dating networks where a transmitted visual depiction of the
person is important. The transmitted visual image of a person
communicating over the Internet with other persons (not previously
introduced) is likely to determine whether a subsequent in-person
introduction will ever occur. Consequently, the quality of the
images transmitted over the Internet is very important and can only
be accomplished by an accurate representation of the person
transmitting the image.
[0005] Often, the image transmitted from the web camera to a
receiving laptop computer or desktop computer is a poor
representative image of the person on the transmitting end. Facial
flaws and/or contour flaws may be accentuated and projected in the
transmitted visual image. Unfortunately, blatant inaccuracies of
the subject person may result in an unfavorable image at the
receiving computer. This situation may result in unsuccessful
attempts at utilizing the social network.
[0006] State of the art laptop computers and desktop computers may
include either (1) an integrated web camera that is incorporated
into the flat screen monitor design, or (2) a stand-alone
aftermarket web camera that is physically attached to the top edge
of the computer flat screen monitor. Generally, the ambient light
level available in the room or space where the laptop computer or
desktop computer is utilized is inadequate to transmit a clear
image of the computer operator over the Internet. In particular,
the primary cause of these visual image transmission problems in
the prior art laptop computers and desktop computers that are
fitted with web cameras is attributable to inadequate, insufficient
or non-existent lighting and/or non-diffusion of the available
light. Consequently, the visual image transmitted is of poor
quality.
[0007] Thus, there is a need in the art for a universal lighting
system for use with a computer web camera having a light array
comprised of a plurality of efficient, long lasting Light Emitting
Diodes (LED) positioned on the distal end of an adjustable
telescopic arm for increasing the ambient light level about the
computer subject, a light diffuser lens positioned on the distal
end of a flexible arm for evenly diffusing the received image light
prior to being transmitted over a worldwide communication network
such as the Internet via the web camera, and a base clamping
mechanism for attaching the universal lighting system to the top
edge of the flat screen monitor of either a laptop computer or a
conventional desktop computer whether the web camera is an
integrated type or a stand-alone, after-market type.
DISCLOSURE OF THE INVENTION
[0008] Briefly, and in general terms, the present invention
provides a new and improved universal lighting system for use with
a computer web camera typically associated with a digital computing
device such as a laptop computer or a desktop computer. The
computer web camera can be integrated into a monitor screen of the
laptop computer, or can be an aftermarket, stand-alone apparatus
mechanically attached to the monitor screen of the desktop
computer. The function of the web camera is to capture the image of
a computer operator, that is, the subject, for transmission over a
worldwide communications network such as the Internet.
[0009] In a preferred embodiment, the universal lighting system for
use with a computer web camera comprises at least three main
structural components. These structural components include a base
clamping mechanism for attaching the universal lighting system to a
flat screen monitor of the digital computing device, a light array
adjustably connected to the base clamping mechanism for
illuminating the subject positioned in front of the computer web
camera, and a light diffuser lens flexibly connected to the base
clamping mechanism and positioned over the web camera for evenly
diffusing the light received from the illuminated subject for
ensuring the creation of a clear image of the subject. The clear
image of the subject is then transmitted over the worldwide
communication network to an intended destination. Thus, the
universal lighting system of the present invention addresses and
solves the problem of inadequate lighting resulting in poor quality
and/or distorted images originating at the transmitting computing
device.
[0010] The base clamping mechanism serves as the main attachment
component for affixing the universal lighting system of the present
invention to the flat screen monitor of the digital computing
device. The base clamping mechanism comprises a clamping jaw
including a front lip that fits directly over the top edge of the
flat screen monitor. An adjustable clamp wheel having a knurled
handle and a threaded shaft is used to physically tighten the
clamping jaw onto the flat screen monitor. Affixed to the base
clamping mechanism is a tension swivel joint to which a telescopic
arm is connected. The telescopic arm includes the light array
affixed to a first distal end thereof. A battery compartment and a
push-button light switch are also included in the base clamping
mechanism for energizing and controlling the electrical power
distributed to the light array. Also attached to the base clamping
mechanism via a flexible arm is the light diffuser lens.
[0011] The light array functions to illuminate the subject
positioned in front of the web camera so as to provide adequate
lighting to enable the digital web camera to create a clear and
undistorted image of the subject for transmission over the
worldwide communication network. The light array is fashioned in
the form of a ring-shaped lamp having a plurality of light emitting
diodes (LEDs) for generating the illumination. The light emitting
diodes (LEDs) are employed because of their high efficiency and
efficacy in lighting circuits. The ring-shaped light array is
located at the end of the adjustable telescopic arm which, in turn,
is connected to the tension swivel joint affixed to the rear side
of the base clamping mechanism. Consequently, the ring-shaped light
array is adjustable through a complete range of motion since the
telescopic arm provides an adjustable radius and the tension swivel
joint provides movement throughout the complete 360 degree range of
angles. The electrical wiring that carries the electrical power to
the light emitting diodes fitted within the light array is
circuited through the telescopic arm, the light switch and
ultimately to the battery power supply.
[0012] The light diffuser lens functions to diffuse light received
from the illuminated subject positioned in front of the web camera.
The received light is passed through the diffuser lens that is
positioned over the web camera associated with the flat screen
monitor. The use of the diffuser lens results in an even
redistribution of the received light rays to reduce the distortion
of the image often associated with web cameras, and to enable the
web camera to create a clear image of the illuminated subject prior
to transmission of the image over the communication network. The
diffuser lens is surrounded by a light seal comprised of a suitable
material such as, for example, rubberized neoprene. The light seal
formed about the diffuser lens serves to block the entry of stray
light into the web camera thereby further reducing potential
distortion of the subject image. The light diffuser lens is mounted
on the end of the flexible arm which enables the diffuser lens to
be manually positioned over the web camera notwithstanding whether
the web camera is integrated into the flat screen monitor or is an
aftermarket, stand-alone web camera attached to the flat screen
monitor. The flexible arm is then physically attached to the base
clamping mechanism.
[0013] The present invention is generally directed to a universal
lighting system for use with a computer web camera including a
digital computing device fitted with a web camera for capturing
images of a subject for transmission over a worldwide communication
network. A base clamping mechanism is affixed to the computing
device. A light array is adjustably connected to the base clamping
mechanism for illuminating the subject positioned before the web
camera. A diffuser lens is flexibly connected to the base clamping
mechanism and sealingly positioned over the web camera for
diffusing received light for creating a clear image of the
illuminated subject prior to transmission over the communication
network.
[0014] These and other objects and advantages of the present
invention will become apparent from the following more detailed
description, taken in conjunction with the accompanying drawings

DETAILED DESCRIPTION OF THE INVENTION
[0024] The present invention relates to a universal lighting system
100 as shown in FIGS. 1-8 for use with a computer web camera 102
associated with a digital computing device 104, the universal
lighting system 100 including a light diffuser lens 106 for use
with a flat screen monitor 108 of the digital computing device 104.
The flat screen monitor 108 is fitted with the web camera 102 for
enhancing and clarifying while reducing distortion flaws of an
image of a computer subject (not shown) generated by the web camera
102 for transmission over a worldwide communication network such as
the Internet (not shown).
[0025] In a preferred embodiment, the present invention is directed
to the universal lighting system 100 for use with the computer web
camera 102, the lighting system 100 comprised of three main
structural components including (1) a light array 110 comprised of
a plurality of efficient, long lasting Light Emitting Diodes (LEDs)
112 attached to a first distal end 114 of an adjustable telescopic
arm 116 for increasing the ambient light level about the computer
subject (not shown). The (2) light diffuser lens 106 is flexibly
connected to a second distal end 118 of a flexible arm 120 for
evenly diffusing the reflected image light received by the web
camera 102 prior to being transmitted over the worldwide
communication network. Finally, (3) a base clamping mechanism 122
is provided for adjustably connecting and securing the light
diffuser lens 106 and the light array 110 of the universal lighting
system 100 to a top edge 124 of the flat screen monitor 108 of the
digital computing device 104. It is noted that the digital
computing device 104 can be either a laptop computer as shown in
FIG. 1 or a conventional desktop computer as shown in FIG. 3.
Likewise, the computer web camera 102 can be integrated into the
flat screen monitor 108 as shown in FIG. 1, or the web camera 102
can be a stand-alone, after-market type physically attached to the
top edge 124 of the flat screen monitor 108 as shown in FIG. 3.
[0026] The Internet is a massive network of networks, that is a
networking infrastructure that is pervasive worldwide. The Internet
connects millions of computers together globally forming a network
in which any computer can communicate with any other computer as
long as they are both connected to the Internet. Consequently,
members of social networks that communicate over a worldwide
communication network such as the Internet must have use of a
digital computing device 104 that is compatible with the Internet.
Digital computing devices 104 are available in both portable and
non-portable configurations. Therefore, the universal lighting
system 100 of the present invention for use with the computer web
camera 102 has been adapted for use with digital computing devices
104 of both the laptop computer and the desktop computer
configurations. In either case, the computer web camera 102
functions to capture the image of the computer subject (typically
the computer operator) for transmission over the worldwide
communication network such as the Internet.
[0027] An illustration of the laptop type of digital computing
device 104 is shown in FIG. 1 and includes a computer casing 126
upon which a keyboard 128 is mounted. Moveably hinged to the
computer casing 126 is a flat screen monitor 108 having a computer
web camera 102 integrally formed therein. Likewise, an illustration
of the desktop type of digital computing device 104 is shown in
FIG. 3 and includes the aftermarket, stand-alone computer web
camera 102 physically mounted upon the top edge 124 of the flat
screen monitor 108. The flat screen monitor 108 is supported by a
support stand 130 and a separate keyboard 128 is shown positioned
in front of the flat screen monitor 108. It is noted that the
universal lighting system 100 for use with the computer web camera
102 is also adaptable to other configurations of the digital
computing devices 104 not illustrated herein. Those alternative
configurations of the digital computing devices 104 might include
but are not limited to a laptop computer fitted with an
aftermarket, stand-alone computer web camera 102 or, in the
alternative, a desktop computer fitted with an integral web camera
102.
[0028] The base clamping mechanism 122 functions as the main
attachment component for securing the universal lighting system 100
of the present invention to the top edge 124 of the flat screen
monitor 108 of the digital computing device 104. The base clamping
mechanism 122 comprises a clamping jaw 134 including a front lip
136 that seats directly over the top edge 124 of the flat screen
monitor 108 best shown in FIG. 5. A view of the front lip 136 of
the base clamping mechanism 122 seated on the top edge 124 of the
flat screen monitor 108 is also shown in FIGS. 2 and 4. The
clamping jaw 134 is tightened against the top edge 124 of the flat
screen monitor 108 by employing an adjustable clamp wheel 138
having a knurled handle for manually advancing and retracting a
threaded shaft 140. The threaded shaft 140 is supported by a clamp
structure 142 of the clamping jaw 134 as shown in FIG. 5. By
turning the adjustable clamp wheel 138 by the knurled handle in the
appropriate direction, the threaded shaft 140 is advanced through
the clamp structure 142 and against a rubber foot 144. The rubber
foot 144 is positioned between a terminal end of the threaded shaft
140 and the rear side of the flat screen monitor 108. Furthermore,
positioned between the front lip 136 of the clamping jaw 134 and
the front side of the flat screen monitor 108 is a felt pad 146.
Both the rubber foot 144 and the felt pad 146 serve to protect the
surface of the flat screen monitor 108 from damage potentially
caused by the clamping jaw 134 of the base clamping mechanism
122.
[0029] Also affixed to the backside of the base clamping mechanism
122 is a tension swivel joint 148 to which the adjustable
telescopic arm 116 is moveably connected. The tension swivel joint
148 provides a broad adjustable range of rotational motion for the
telescopic arm 116. The range of motion enjoyed by the telescopic
arm 116 as a result of the tension swivel joint 148 is potentially
up to 360-degrees but more likely an arc of 180-degrees (Pi
radians). This range of motion can be defined by the angular arc
150 that the adjustable telescopic arm 116 would travel from the
left side of the top edge 124 to the right side of the top edge 124
of the flat screen monitor 108 as shown in FIGS. 2 and 4. Likewise,
the telescopic arm 116 could conceivably also be adjusted either
forward or backwards at the tension swivel joint 148, e.g., the
telescopic arm 116 being adjusted either into the plane of the
paper or out of the plane of the paper as viewed in FIGS. 2 and 4.
This very liberal arc range of motion combined with the
translational motion provided by the extension and contraction of
the telescopic arm 116 enables the light array 110 to be positioned
at almost any required location to illuminate the computer subject
located before the computer web camera 102. Consequently, the
tension swivel joint 148 enjoys three degrees of freedom since it
can be adjusted (1) back and forth, (2) side-to-side, and (3) along
the translational path.
[0030] Also formed on the backside of the base clamping mechanism
122 is a battery compartment 152 and a light switch 154. The
battery compartment 152 includes an access door 156 for housing a
plurality of low voltage (direct current) batteries 158 for
providing the electrical power necessary to energize the light
array 110 mounted on the first distal end 114 of the telescopic arm
116. The batteries 158 can be, for example, of the nickel-cadmium
variety. Electrical wires (not shown) employed to carry the
electrical current from the batteries 158 to the light array 110
are circuited from the batteries 158, through the light switch 154
and on to the light array 110 via the telescopic arm 116. The light
switch 154 can be an industry standard spring-loaded (push button)
device employed to carry rated current drawn from the battery 158
through the light emitting diodes (LEDs) 112 of the light array 110
as shown in FIG. 2A. In FIG. 2A, the light emitting diodes (LEDs)
112 are shown as an electrical load, i.e., a resistor. Thus, the
combination of the batteries 158 and the light switch 154 included
within the base clamping mechanism 122 serve to energize and
control the electrical power distributed to the light array 110.
Finally, the flexible bendable arm 120 is connected to the base
clamping mechanism 122 for supporting the light diffuser lens 106.
The light diffuser lens 106 is flexibly connected to the second
distal end 118 of the flexible arm 120 as is clearly shown in FIG.
8. The light diffuser lens 106 serves to evenly diffuse the
reflected image light received by the web camera 102 from the
computer subject (not shown) prior to being transmitted over the
worldwide communication network.
[0031] The light array 110 is adjustably connected to the base
clamping mechanism 122 via the adjustable telescopic arm 116 for
illuminating the subject (not shown) positioned in front of the
computer web camera 102 best shown in FIGS. 2, 4 and 7. By
illuminating the subject positioned before the computer web camera
102, the light array 110 functions to provide adequate lighting to
enable the digital computer web camera 102 to create a clear and
undistorted image of the subject for transmission over the
worldwide communication network. The light array 110 is fashioned
in the form of a ring-shaped lamp sometimes referred to as ring
lighting. The ring lighting provides the advantage of a better
distribution of light rays onto the computer subject (typically the
computer operator) to avoid creating shadows. The ring-shaped lamp
of the light array 110 is typically fabricated as a plastic loop
which incorporates the plurality of light emitting diodes (LEDs)
112 for generating the illumination. The light emitting diodes 112
are employed as the light generating source in the light array 110
because of their high efficiency and efficacy in lighting
circuits.
[0032] The ring-shaped light array 110 is positioned at the first
distal end 114 of the telescopic arm 116, the length of which is
manually adjustable due to the telescopic construction. The
telescopic arm 116 typically will include a telescopic extension of
4''-to-8'' of travel. The telescopic arm 116 is physically
connected to the tension swivel joint 148 mounted to the rear side
of the base clamping mechanism 122. The tension swivel joint 148
provides a broad range of adjustable rotational motion having three
degrees of freedom. The rotational range of motion provided by the
tension swivel joint 148 enables the telescopic arm 116 to easily
travel across broad arcs of 180-degrees (Pi radians) or more. This
range of motion easily enables the light array 110 to span the
entire length of the top edge 124 of the flat screen monitor 108 as
is indicated by the angular arc 150 shown in FIGS. 2 and 4. This
rotational range of motion provided by the tension swivel joint 148
combined with the telescopic extension and contraction of the
telescopic arm 116 enables the light array 110 to be positioned at
almost any required location to illuminate the computer subject
located before the computer web camera 102. Consequently, the
ring-shaped lamp comprising the light array 110 is adjustable
through a complete range of motion because the telescopic arm 116
provides an adjustable radius and the tension swivel joint 148
provides broad rotational movement.
[0033] The light emitting diodes 112 mounted on the ring-shaped
light array 110 must be energized by the low voltage direct current
power provided by the power supply, e.g., the batteries 158,
located within the battery compartment 152. The required electrical
power travels over the electrical wiring (not shown) that is
circuited from the batteries 158 through the push-button light
switch 154 and into the adjustable telescopic arm 116. The
telescopic arm 116 serves as a conduit to carry the electrical
wiring to the light emitting diodes 112 of the light array 110. The
light emitting diodes 112 would typically be wired in a parallel
configuration and would be energized to glow for producing light
once the light switch 154 has been actuated.
[0034] The light diffuser lens 106 shown clearly in Applicant's
FIGS. 2, 4, 7 and 8 functions to diffuse light received from the
illuminated subject (not shown) positioned in front of the computer
web camera 102. The received light is passed through the light
diffuser lens 106 that is positioned to cover the computer web
camera 102 associated with the flat screen monitor 108. The use of
the light diffuser lens 106 results in an even redistribution of
the received light rays to reduce the distortion of the image often
associated with the computer web camera 102. Further, the light
diffuser lens 106 enables the web camera 102 to create a clear
image of the illuminated subject (not shown) prior to transmission
of the image over the worldwide communication network.
[0035] The light diffuser lens 106 is surrounded by a light seal
160 comprised of a suitable material such as, for example,
rubberized neoprene. However, it is understood that any suitable
material whether natural or synthetic can be employed for use as
the light seal 160. The light seal 160 formed about the light
diffuser lens 106 serves to block admission of stray light into the
computer web camera 102 that would otherwise serve to interfere
with the operation of the light diffuser lens 106 mounted over the
web camera 106. This action is accomplished in the following
manner. The material comprising the light seal 160 adheres to the
front surface of the computer web camera 102 or to the flat screen
monitor 108 depending upon which configuration of the computer web
camera 102 is being utilized (i.e., aftermarket stand-alone
computer web camera or integrated computer web camera).
Consequently, the light seal 160 further reduces potential
distortion of the subject image prior to transmission over the
worldwide communication network. In other words, the image
generated by the computer web camera 102 is enhanced and clarified
prior to being transmitted to the recipient via the Internet.
[0036] The light diffuser lens 106 is physically mounted at the
second distal end 118 of the flexible arm 120 as is clearly shown
in FIGS. 2, 4, 7 and 8. The flexible arm 120 is a bendable or
malleable extension that is capable of being manually manipulated
so as to position the light diffuser lens 106 attached to the
flexible arm 120 in a desired direction. This design enables the
light diffuser lens 106 to be manually positioned over the computer
web camera 102 notwithstanding whether the web camera 102 is
integrated into the flat screen monitor 108 or is an aftermarket,
stand-alone web camera mounted on the flat screen monitor 108. A
proximal end 162 of the flexible arm 120 is then physically
attached to the base clamping mechanism 122 as is clearly shown in
FIGS. 6 and 8.
[0037] The universal lighting system 100 for use with a computer
web camera 102 is employed for increasing the light level projected
onto the computer subject (typically the computer operator) and for
diffusing the light reflected from the illuminated subject and
received by the computer web camera 102. The enhanced projected
light level and the diffusion of the reflected light provide a
better distribution of light rays that minimizes shadows and serves
to enhance and clarify the image generated by the computer web
camera 102 prior to being transmitted over the worldwide
communication network. In operation, the base clamping mechanism
122 is fitted onto the top edge 124 of the flat screen monitor 108.
The top edge 124 of the flat screen monitor 108 is positioned
between the front lip 136 and the clamp structure 142 of the base
clamping mechanism 122 ensuring that the rubber foot 144 and the
felt pad 146 are in position to protect the rear and front sides of
the flat screen monitor 108, respectively. Thereafter, the knurled
handle of the adjustable clamp wheel 138 is turned in the
appropriate direction to tighten the base clamping mechanism 122
onto the flat screen monitor 108. Thereafter, the telescopic arm
116 is adjusted in length and in its angular position as it relates
to the tension swivel joint 148 so that the light array 110 is
directed towards the computer subject. Next, the flexible arm 120
is manually adjusted so that the light diffuser lens 106 is
positioned directly over the computer web camera 102. The light
seal 160 is then pressed against the computer web camera 102 or the
flat screen monitor 108 (depending upon the type of web camera
being utilized) to block the admission of stray light. Next, the
battery compartment access door 156 is opened to insure that
charged batteries 158 have been installed. Finally, the
spring-loaded light switch 154 is actuated to energize the light
emitting diodes 112 for illuminating the computer subject. The
computer operator can now utilize the computer web camera 102 to
transmit the illuminated image over the worldwide communication
network with confidence that the transmitted image will be free
from distortion and shadows.
[0038] Thus, the universal lighting system 100 for use with the
computer web camera 102 includes a digital computing device 104
fitted with a computer web camera 102 for capturing images of a
computer subject for transmission over a worldwide communication
network. A base clamping mechanism 122 is affixed to the digital
computing device 104. A light array 110 is adjustably connected to
the base clamping mechanism 122 for illuminating the computer
subject positioned before the web camera 102. A light diffuser lens
106 is flexibly connected to the base clamping mechanism 122 and
sealingly positioned over the computer web camera 102 for diffusing
received light for creating a clear image of the illuminated
subject prior to transmission over the communication network.
[0039] The present invention provides novel advantages over other
computer web camera systems known in the prior art. A main
advantage of the universal lighting system 100 of the present
invention for use with a computer web camera 102 is (1) the
computer operator is illuminated, and (2) the light reflected to
the computer web camera 102 from the illuminated subject enhances,
clarifies and minimizes distortion of the image being generated
prior to transmission across the worldwide communication network,
(3) that the base clamping mechanism 122 is conveniently mounted
and attached to the flat screen monitor 108, (4) that the light
array 110 includes a plurality of high efficiency light emitting
diodes 112 for providing an even distribution of light rays onto
the computer subject for avoiding shadows, (5) that the extension
length and angular position of the light array 110 can be adjusted
(6) that the universal lighting system 100 is applicable to both
laptop or desktop computers, (7) that a light seal 160 surrounds
the light diffuser lens 106 for preventing the admission of stray
light that would otherwise interfere with the operation of the
light diffuser lens 106 and the computer web camera 102, and (8)
that the flexible arm 120 is bendable and malleable so that the
light diffuser lens 106 can be positioned directly over the
computer web camera 102 notwithstanding its position,
[0040] While the present invention is described herein with
reference to illustrative embodiments for particular applications,
it should be understood that the invention is not limited thereto.
Those having ordinary skill in the art and access to the teachings
provided herein will recognize additional modifications,
applications and embodiments within the scope thereof and
additional fields in which the present invention would be of
significant utility. For example, it is within the scope of the
present invention to provide a laptop type of digital computing
device 104 fitted with an aftermarket, stand-alone computer web
camera 102 or, in the alternative, a desktop type of digital
computing device 104 fitted with an integral web camera 102. Both
of these embodiments are foreseeable and are within the scope of
the present invention.
[0041] It is therefore intended by the appended claims to cover any
and all such modifications, applications and embodiments within the
scope of the present invention. Accordingly,
