Abstract
Systems and methods described for adaptive edge dimming are disclosed. A video processing system analyzes video frames in a video stream, and determines display settings corresponding to a target display device. The system further analyzes aspect ratio of the frame, excluding any black bars, with respect to aspect ratio of the display (or playback window in windowed mode). Based on this comparison the system adaptively applies edge dimming to exclude the black bars. Edge dimming can also be implemented as a hybrid solution, wherein the source detects the region for edge-dimming and transmits metadata to the sink device for applying the edge-dimming.
Claims20
A processor comprising:
- circuitry configured to:
- receive a video frame;
- responsive to meeting a condition, generate a modified video frame by modifying selected pixels of the video frame identified as corresponding to a given region of the video frame;
- and
- convey the modified video frame to a target display device for display.
A method comprising:
- receiving, from a video source by a video processing circuitry, a video frame;
- responsive to meeting a condition, generating, by the video processing circuitry, a modified video frame by modifying selected pixels of the video frame identified as corresponding to a given region of the video frame;
- and
- conveying, by the video processing circuitry, the modified video frame to a target display device for display.
A video processing system comprising:
- a memory to store a video frame;
- and
- a processor configured to:
- responsive to meeting a condition, generate a modified video frame by modifying selected pixels of the video frame identified as corresponding to a given region of the video frame;
- and
- convey the modified video frame to a target display device for display.
