ADAPTIVE AUTO EXPOSURE ADJUSTMENT |
摘要 |
Techniques for adjusting exposure parameters of a camera such that video data captured by the camera may be coded efficiently. A camera with auto exposure control may capture and output frames of video. A pre-processor may estimate brightness of the frames of the video output from the camera. A controller may estimate a rate of brightness change among the frames, and when the rate of change is lower than a predetermined threshold, the controller may reduce sensitivity of the auto exposure control. A coding engine may predictively code the video.
