Backlight enhancement device that responds to video signals generated at the far end Cross reference

The present application claims priority to U.S. Provisional Application No. 62/054, 720, filed on Sep. 24, 2014, the entire disclosure of which is incorporated herein by reference.

This embodiment relates to video telephony, and in particular, the present embodiment relates to a configuration for enhancing light conditions exposed by a participant in a video conference.

Video conferencing using, for example, Skype or Facetime has become a common tool in the home environment. In a video conference, a video camera is used to allow remote participants to observe and hear each other. When a participant is exposed to insufficient light conditions, the image of the participant displayed at the receiving end may have a low quality. It may be desirable to use light generated in a display screen to illuminate or illuminate a face/face of one of the participants in the video conference.

A first participant and, for example, a remote second participant can participate in the video conference. The videophone device used by the remote end and the second participant can generate a video signal, for example, the signal contains, for example, a camera captured by the remote, second participant's face. The generated video signal is transmitted via a communication network such as the Internet.

In an advantageous embodiment, the transmitted video signal is received via the communication network as an input video signal to one of the video processors, and the video processor is used by the first participant. One of the video telephony devices (for example, a smart phone, a television receiver, a personal computer, or a tablet) is used. The video processor generates a display driven video signal containing, for example, the captured image of the far end, the head/face of the second participant, for display in a display panel of one of the first participant's video telephony devices.

The video processor also generates a first transmitter to drive the video signal. The first transmitter driving video signal is applied via a communication network and configured to be displayed in a first area of a display panel of one of the second participant's video telephony devices for enhancing the remote second participant Background illumination exposed by a target of one of the video telephony devices.

The video processor is further responsive to the input video signal for estimating illumination (eg, the luminance content of the received input video signal) and for adjusting the first one in a negative feedback manner based on the estimated luminance content of the received input video signal The transmitter drives the brightness content of the video signal. For example, if the input video signal has low brightness, then the first transmitter driving the video signal will cause one of the light generated in the first region of the display to increase. Thus, the backlight applied to the target of the second participant's camera will be increased in a manner to increase the brightness associated with the input video signal.

The video processor is further responsive to a video signal generated by a camera containing, for example, an image of the face/head of the first participant for generating a second transmitter to drive the video signal. The second transmitter driving video signal is applied to the communication network and configured to be displayed in a second area that is associated with the first area of the display panel of the far end videophone device of the second participant separate. The image produced in the first region, for example, is independent of the image produced in the second region.

A video communication device for employing an advantageous method includes an interface capable of receiving an input video signal from a communication network, the input video signal containing a first image capable of being displayed in a first display panel. A video processor is configured to estimate illumination content of the input video signal and is configured to generate a first output transmitter based on the illumination content estimate Driving a video signal, the first output transmitter driving video signal can be transmitted in the communication network and, when received from the communication network, can be displayed in a first area of a second display panel, thereby The background light adjusted according to the illumination content estimate is generated in the area. The video processor responds to the second video signal including a second image for generating a second output transmitter driving video signal including the second image, and the second output transmitter drives the video signal to be in the communication network. The medium transmission and when received from the communication network can be displayed in a second area of one of the second display panels.

1A depicts, for example, a block diagram of a prior art smart phone 300 operated by a participant A who participates in a video conference with one of FIG. 1B, located, for example, from a participant. The far end of B. FIG. 1B illustrates a block diagram of one of the smart phones 200 that provides an advantageous feature and is operated by participant B. Like reference numerals and numerals in FIGS. 1A and 1B indicate analog items or functions.

2A shows an image 101a of a participant A of FIG. 1A. The image is captured by a camera 307 of the telephone 300 for generating a video signal 307a containing the captured image 101a of FIG. 2A. The image 101a includes a picture portion 101b depicting one of the heads/faces of the participant A, an image portion 101c depicting one of the subjects A, and a background portion 101d excluding one of the other two image portions. Like reference numerals and numerals in FIGS. 1A, 1B and 2A indicate analog items or functions.

The video signal 307a of FIG. 1A is substantially non-video or picture image content is modified to be coupled to one of the conventional receivers of the telephone 300 via a conventional video processor 302 (eg, implemented in a microprocessor not shown). - Transmitter stage 303. The receiver-transmitter stage 303 of the video processor 302 transmits the content of the video signal 307a in a conventional manner via a telephone or data/internet communication network 400. One of the conventional receiver-transmitter stages 205 of FIG. 1B receives a signal transmitted by the receiver-transmitter stage 303 of FIG. 1A via a network 400, which includes the image 101a of FIG. 2A forming one of the input video signals 205a of FIG. 1B. . The input video signal 205a contains the same video or picture video content as the image 101a of FIG. 2A.

Advantageously, one of the video processors 206 of FIG. 1B (eg, implemented in a microprocessor not shown) uses known pattern recognition techniques to detect or recognize the participant A in the input video signal 205a that depicts FIG. 1A. A portion of the signal (not shown) of image portion 101b of one of FIG. 2A of the head/face image. Alternatively, the detected or identified portion may also include a portion 101a of the portion of the background portion 101d in addition to the signal portion associated with the head/face image portion 101b. Use similar to, for example, US 6,661,907, US 6,343,141 and according to January 2002, Vol. 24, IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE One of the identification methods described in the article "Detecting Faces in Images: A Survey" is performed to detect or recognize the head/face included in the image portion 101b.

The aforementioned portion (not shown) of video signal 205a containing header/face image portion 101b of Figure 2A of participant A is extracted and applied to a video processor 203 to produce a display driven video signal 203b. In addition, the video processor 203 of FIG. 1B synthesizes a display drive video signal 203c that is combined with the display drive video signal 203b to form a combined display drive video signal 203a. Therefore, the signal 203a includes both the display drive video signal 203c and the display drive video signal 203b. The display driving video signal 203c and the display driving video signal 203b are applied to a conventional display device 204c having a display panel 204. In the display panel 204, the display driving video signal 203b generates an image portion in an area 204b of the display panel 204 of FIG. 2B having, for example, the same picture image content as the head/face image portion 101b of FIG. 2A and Reference is made in Figure 2B using the same reference numeral 101b. Like reference numerals and numerals in FIGS. 1A, 1B, 2A and 2B indicate analog items or functions.

Advantageously, the composite display drive video signal 203c of FIG. 1B produces light in a region 204a of the display panel 204 of FIG. 2B that excludes the head/face image portion 101b and does not overlap the region 204b of the display panel 204. The light generating region 204a is for generating and adjusting illumination in the region 204a to illuminate, for example, the head/face of the participant B who forms the target of a camera 207.

3 illustrates an image 201a forming a target of the camera 207, which is captured in the camera 207 of FIG. 1B of the participant B. Like reference numerals and numerals in FIGS. 1A, 1B, 2A, 2B and 3 indicate analog items or functions.

The image 201a of FIG. 3 depicts a head/face image portion 201b of the participant B, a body image portion 201c of the participant B, and a background image portion 201d of the at least head/face image portion 201b of the participant B. One of the video signals 207a of FIG. 1B contains the image 201a of FIG. Processing the video signal 207a of FIG. 1B in a video processor 202, for example, not shown The video processor 202 is implemented in the same microprocessor, and the microprocessor also implements the processor 203 and the processor 206 mentioned above. Accordingly, video processor 202, video processor 203, and video processor 206 can be combined to form a single video processor 250.

Advantageously, the video processor 202, using one of the aforementioned pattern recognition techniques, detects or recognizes and extracts a signal portion (not shown) of the video signal 207a that contains the head of FIG. 3 of participant B of FIG. 1B/ The image pattern of the face image portion 201b excludes the rest of the image 201a. Alternatively, the video content of the band portion 201e may also be included in the detected and extracted portion.

Advantageously, the video processor 202 of FIG. 1B estimates the illumination exposure parameters by analyzing the detected and extracted portions (not shown) of the video signal 207a of FIG. 1B containing the head/face image portion 201b of FIG. 3, for example, The brightness, the signal-to-noise ratio content of the image 201a or other optical characteristics (such as color) of the captured image 201a of FIG. 3, or a combination thereof. Alternatively, a combination of the head/face image portion 201b and, for example, the band 101e can be used for this estimation. Lighting or brightness estimation uses a known pixel signal integration procedure.

In an alternative, the entire content of the integration program is applied to the captured image 201a of participant B of FIG. In other alternatives, the integration procedure is simply applied to the head/face image portion 201b or the head/face image portion 201b of the captured image 201a applied to the participant B of FIG. 1B in combination with one of the portions 201e. One of the output signals 202a of the processor 202 contains a value indicative of illumination (such as exposure of the aforementioned luminance content of the image of participant B).

The estimate may indicate that the illumination of the head/face image portion 201b of Figure 3 is insufficient to be below a threshold level. Advantageously, the combination of the luminance content, the color content and the gamma correction value contained in the display drive video signal 203c of the video content of the header/face image portion 101b of FIG. 2A is excluded, for example, by a closed loop negative feedback method. Make adjustments. This adjustment is performed in accordance with the estimated illumination/luminance content in signal 202a of Figure IB. Thus, the light of the light generating region 204a of FIG. 2B of the exclusion region 204b is controlled in a manner to change the exposure of the target of the camera 207 of FIG. 1B, such as the head/face of the participant B. The illumination of the light generating region 204a of FIG. 2B is obtained for Enhance all lighting or brightness content, contrast and/or color temperature in a closed loop negative feedback mode. The adaptive sensing signal 202a also changes whenever the lighting environment changes. The brightness and/or color content of light generating region 204a of Figure 2B can be increased to obtain white with maximum light output.

The conditioned light output can be controlled by, for example, controlling a light valve or unit (not shown) that forms a pixel of display panel 204, using, for example, liquid crystal display (LCD) or organic light emitting diode (OLED) technology. These pixels are formed. When, for example, LCD technology is used, the conditioned light output can be additionally or alternatively controlled by selectively controlling backlighting (not shown) of display panel 204. Advantageously, the head/face image portion 201b of one of the participants B of FIG. 1B is thereby improved or better illuminated. For example, if Participant B is in a darkroom and is directed to the external illumination (not shown) of Part B of the Participant B, the luminance content of the light generating area 204a of FIG. 2B is a negative feedback. The mode is increased to an optimal value for obtaining enhanced illumination of the head/face of participant B of FIG. The result is that the signal 207a of the camera 207 of Figure 1B will contain the image 201a of the participant B of Figure 3, which is advantageously and optimally brighter.

In one example, signal 207a of camera 207 of FIG. 1B is applied to transmitter-receiver stage 205 in video processor 203, and transmitter-receiver stage 205 transmits image 201a containing FIG. 3 via communication network 400. A transmitter of the processor 203 drives the video signal 203d. At a remote end, the receiver-transmitter stage 303 of FIG. 1A receives the transmitted drive video signal 203d and displays the transmitted drive video signal 203d (eg, unmodified) on one of the display devices 304c of the telephone 300. In panel 304.

The enhanced illumination conditions generated in the light generating region 204a of FIG. 2B, controlled by the negative feedback control loop, cause the image 201a of FIG. 3 to be advantageously brightly displayed when displayed in the display panel 304 of FIG. 1A of the participant A. . Thus, advantageously, even prior art telephone 300 also benefits from the advantageous features of advantageous telephone 200 of FIG. 1B.

Advantageously, in particular, the color temperature of the skin of the image of participant B of FIG. 1B can be analyzed by processor 202. As explained above, the processor 203 can be based on the processor of FIG. 1B. The analysis result of 202 changes the color of the light generating region 204a of Fig. 2B. As a result, the image 201a of Participant B of FIG. 3 transmitted to Participant A of FIG. 1A may become (favorably) more decent or so-called look healthier. If the target of the camera 207 of FIG. 1B contains more than one person (eg, a family) that causes more than one single head/face in the picture, each head/face can be detected or identified and considered to be relative to a single Participant B is displayed in a similar manner as described earlier.

Advantageously, to mitigate partial exposure, an underexposed head/face portion can be selectively illuminated by the light generating region 204a of the display 204 to primarily illuminate the darker side in an asymmetrical manner. When, for example, an external light source (not shown, such as a light) primarily illuminates the result of one side of participant B's face, only a portion of the image is insufficiently illuminated, a partial exposure occurs. 4A, 4B and 4C illustrate three examples of so-called asymmetric illumination. Like reference numerals and numerals in FIGS. 1A, 1B, 2A, 2B, 3, 4A, 4B, and 4C indicate analog items or functions. In FIGS. 4A and 4B, the light generating region 204a occupies only one of the right portions of the display panel 204 for generating a light output on the right side of the image of the participant A, which is directed to the head/face of the participant B of FIG. 1B. . In the example of Figure 4B, the proportional dimensions of the head/face portion 101b are scaled down and repositioned to the left and below. However, the area of the light generating region 204a becomes larger proportionally in FIG. 4A to allow for better asymmetric illumination.

In Figure 4C, the head/face image portion 101b is repositioned to a corner or side, the remainder of the allowable area producing more light output at the lower and right sides of the head/face portion 101b, which is directed to Figure 1B. Participant B's head/face. The area size occupied by the light generating regions 204a of FIGS. 4A, 4B, and 4C is adjusted by the processor 203 of FIG. 1B according to the estimated illumination distribution content in the head/face image portion 201b of FIG.

Advantageously, the phone 200 of FIG. 1B can also be used when the camera 207 is used to capture and store, for example, a self-portrait photo, such as a self-portrait, in a manner unrelated to the videophone. The head/face image portion 201b of FIG. 3 of the participant B of FIG. 1B is provided Enhance lighting content. For this purpose, a portion (not shown) of the video signal 207a, which mainly contains the header/face image portion 201b of the participant B, is extracted and applied to the video processor 203 to generate a display driver for the video processor 203. The display of the output video signal 203a drives the video signal 203b. This is accomplished in a similar manner as described earlier with respect to Figure 2B. A main difference is instead of displaying the head/face image portion 101b of the participant A in the display panel 204 of FIG. 2B. The display driving video signal 203b mainly contains the extracted head/face image portion 201b of the participant B of FIG. It is shown in the display panel 204 of FIG. Like reference numerals and numerals in FIGS. 1A, 1B, 2A, 2B, 3, 4A, 4B, 4C, and 5 indicate analog items or functions. In this manner, participant B can observe his head/face image portion 201b captured by camera 207 of FIG. 1B.

Advantageously, if the content illumination estimation performed in the processor 202 indicates that the luminance value of the header/face image portion 201b of FIG. 3 is not sufficiently low, the video is adjusted and displayed in a closed loop negative feedback mode, for example. A combination of luminance content, color content, and gamma correction values associated with signal 203c. This adjustment is performed in accordance with the illumination/brightness content in signal 202a of Figure IB. The illumination of the light generating region 204a of FIG. 5 is controlled in a manner to change the exposure, and the self-portrait picture photographer B is subjected to the exposure in a manner to enhance the overall luminance content, contrast, and color temperature in a closed loop feedback manner. It will be appreciated that the advantageous features described in conjunction with FIG. 2B and FIG. 4A through FIG. 4C may also be applied in a similar manner to one of capturing and storing a self-timer.

As explained above, when participant A of FIG. 1A and participant B of FIG. 1B each participate in a video conference call, a portion of video signal 207a containing header/face image portion 201b of FIG. 3 of participant B (not shown) It is extracted and applied in the video processor 203 of FIG. 1B to generate a transmitter to drive the output video signal 203e. The transmitter drive output video signal 203e is included in the aforementioned transmitter drive output video signal 203d. The transmitter driven video signal 203e has, for example, substantially the same visual content as the aforementioned extracted partial signal of the head/face image portion 201b of FIG. 3 containing only participant B of FIG. 1B. In addition, Figure 1B The video processor 203 synthesizes a signal that is also included in the signal 203d to drive the video signal 203f. Thus, signal 203d containing both signal 203e and signal 203f is applied to receiver-transmitter stage 205, and receiver-transmitter stage 205 transmits signal 203d via network 400. Receiver-transmitter stage 303 of FIG. 1A, which receives signal 203d via network 400, displays signal 203d (eg, without modifying the visual content of signal 203d) in display panel 304 of FIG. 6 of telephone 300 of FIG. 1A. Like reference numerals and numerals in FIGS. 1A, 1B, 2A, 2B, 3, 4A, 4B, 4C, 5, and 6 indicate analog items or functions. In the display panel 304 of FIG. 6, the display driving video signal 203e generates an image portion having, for example, the same visual content as the head/face image portion 201b of FIG. 3 for display on one of the display panels 304 of FIG. In area 304b.

The video processor 206 of FIG. 1B, for example, extracts the header/face image portion 101b of FIG. 2A for display in the display panel 204 of FIG. 1B, in addition to the manner described above, and also estimates the participants from FIG. 1A. A receives the illumination exposure of image 101a of Figure 2A. Alternatively, video processor 206 of FIG. 1B also estimates other optical characteristics, such as the color of received image 101a of FIG. 2A contained in video signal 205a of FIG. 1B. This estimate applies a known pixel signal integration procedure in the manner described with respect to the front of the head/face image portion 201b of FIG.

In an alternative, the entire contents of an integrated program are applied to the content of the captured image 101a of participant A of FIG. 2A. In other alternatives, video processor 206 of FIG. 1B detects or recognizes the pattern of head/face image portion 101b of FIG. 2A. Next, the integration procedure is simply applied to a portion of the signal 205a of FIG. 1B corresponding to the head/face image portion 101b of FIG. 2A or a combination of the image portion 101b and the portion 101e of the captured image 101a applied to the participant A. . The result of this estimation is contained in an output signal 206a of processor 206 which contains a luminance value indicative of the degree of illumination exposure on head/face image portion 101b of Figure 2A of participant A.

In carrying out another particularly advantageous feature, if the analysis of the content of signal 206a of Figure 1B indicates that the illumination/luminance content estimate associated with the image of Participant A of Figure 2A is not Substantially low (e.g., below a threshold level), processor 203 of FIG. 1B synthesizes a transmitter-driven video signal 203f to produce light in a region 304a of FIG. 6 of display panel 304 of FIG. 1B. The area 304a of FIG. 6 excludes the head/face image portion 201b of the area 304b and does not overlap the area 304b of the display panel 304. The light generating region 304a is for generating and adjusting illumination in the region 304a in a negative feedback manner to illuminate, for example, the head/face of the participant A of FIG. 1A that forms the target of the camera 307. This is done (advantageously) for controlling the illumination that illuminates the illumination generating area 204a of FIG. 2B (such as the brightness content of the head/face of participant A in FIG. 1A in a similar manner). Thus, the illumination of the light generating region 304a of FIG. 6 can be controlled in a manner to change the exposure on participant A of FIG. 1A to enhance the overall luminance content, contrast content, and/or color temperature in a closed loop negative feedback manner. The correction signal 206a of Figure 1B is adapted to the change whenever the lighting environment changes. The luminance content of the light generating region 304a of Fig. 6 can be increased to the optimum light output. In a manner similar to that described earlier with respect to Figures 4A, 4B, and 4C, the head/face of participant A can be illuminated by light generating region 304a of display panel 304, which produces light region 304a An asymmetrical manner illuminates a darker side of the head/face image portion 201b of FIG. Like reference numerals and numerals in FIGS. 1A, 1B, 2A, 2B, 3, 4A, 4B, 4C, 5, 6, and 7 indicate analog items or functions.
