Video transcoder based joint video and still image pipeline with still burst mode

摘要

A digital video camera system may utilize a joint video and still image pipeline that simultaneously acquires, processes, transmits and/or stores digital video and high resolution digital still image photographs. The joint pipeline may include a video pipeline optimized for digital video frames and a high resolution still image pipeline optimized for high resolution digital still image frames. The digital video camera system may also concurrently acquire and process video frames and high resolution still image frames in burst mode by downsampling the video frames into reduced size video frames so that the single processing pipeline can allot more time to process the high resolution still image frames in real time. The loss in video quality may be compensated using motion estimation and information from the high resolution still image frames.
