Image changes based on facial appearance

Abstract

In an embodiment, a system includes a display screen, cameras coupled to the display screen, and a processing circuit. The display screen is configured to display a sequence of video images to a viewer. The cameras are coupled to the display screen, configured to capture a facial appearance of a viewer having a view of the display screen, and configured to generate data representing the captured facial appearance. And the processing circuit is configured to receive the data generated by the cameras and to generate the sequence of video images in response to the captured facial appearance.

What is claimed: 
     
         1 . A system, comprising
 a display screen configured to display a sequence of video images to a viewer;   cameras coupled to the display screen, configured to capture a facial appearance of a viewer having a view of the display screen, and configured to generate data representing the captured facial appearance; and   a processing circuit configured:
 to receive the data generated by the cameras, and 
 to generate the sequence of video images in response to the captured facial appearance. 
   
     
     
         2 . The system of  claim 1  wherein the processor is configured:
 to identify the viewer in response to the captured facial appearance; and 
 to generate the sequence of video images in response to the identity of the viewer. 
 
     
     
         3 . The system of  claim 1  wherein the processor is configured to generate the sequence of video images by generating, in response to the captured facial appearance, a moving sprite in the displayed sequence of video images. 
     
     
         4 . The system of  claim 1  wherein the processor is configured to generate the sequence of video images by selecting, in response to the captured facial appearance, a branch of a multi-branch sequence of video images. 
     
     
         5 . The system of  claim 1  wherein the processor is configured to generate the sequence of video images by setting, in response to the captured facial appearance, a brightness of a part of a video image within the sequence of video images. 
     
     
         6 . The system of  claim 1  wherein the processor is configured to generate the sequence of video images by setting, in response to the captured facial appearance, a color of a part of a video image within the sequence of video images. 
     
     
         7 . The system of  claim 1  wherein the processor is configured to generate the sequence of video images by setting, in response to the captured facial appearance, a sharpness of a part of a video image within the sequence of video images. 
     
     
         8 . The system of  claim 1  wherein the processor is configured to generate the sequence of video images by increasing, in response to the captured facial appearance, a magnification of a part of a video image within the sequence of video images. 
     
     
         9 . The system of  claim 1  wherein the processor is configured to generate the sequence of video images by reducing, in response to the captured facial appearance, a magnification of a part of a video image within the sequence of video images. 
     
     
         10 . The system of  claim 1  wherein the processor is configured to generate, in response to the captured facial appearance, a sound. 
     
     
         11 . A method, comprising
 capturing a facial appearance of a viewer having a view of a display screen with cameras coupled to the display screen;   generating data representing the captured facial appearance;   changing a sequence of video images relative to another sequence of video images in response to the captured facial appearance; and   displaying the changed sequence of video images on the display screen.   
     
     
         12 . The method of  claim 11  wherein changing the sequence of video images in response to the captured facial appearance comprises:
 identifying the viewer in response to the captured facial appearance; and 
 changing the sequence of video images in response to the identity of the viewer. 
 
     
     
         13 . The system of  claim 1  wherein changing the sequence of video images includes changing, in response to the captured facial appearance, a movement of a sprite in the displayed sequence of video images. 
     
     
         14 . The method of  claim 11  wherein:
 changing the sequence of video images includes selecting, in response to the captured facial appearance, a branch of a multi-branch sequence of video images; and 
 displaying the changed sequence video images includes displaying the selected branch of the multi-branch sequence of video images as part of the displayed changed sequence of video images. 
 
     
     
         15 . The method of  claim 11  wherein changing the sequence of video images includes changing, in response to the captured facial appearance, a brightness of a part of a video image within the displayed changed sequence of video images. 
     
     
         16 . The method of  claim 11  wherein changing the sequence of video images includes changing, in response to the captured facial appearance, a color of a part of a video image within the displayed changed sequence of video images. 
     
     
         17 . The method of  claim 11  wherein changing the sequence of video images includes changing, in response to the captured facial appearance, a sharpness of a part of a video image within displayed the changed sequence of video images. 
     
     
         18 . The method of  claim 11  wherein changing the sequence of video images includes increasing or reducing, in response to the captured facial appearance, a magnification of a part of a video image within the displayed changed sequence of video images. 
     
     
         19 . The method of  claim 11  wherein changing the sequence of video images includes generating, in response to the captured facial appearance, a sound. 
     
     
         20 . A tangible computer-readable medium storing instructions that, when executed by a processing circuit, cause the processing circuit:
 to capture a facial appearance of a viewer having a view of a display screen with cameras coupled to the display screen;   to generate data representing the captured facial appearance;   to change a sequence of video images relative to another sequence of video images in response to the captured facial appearance; and   to display the changed sequence of video images on the display screen.
