Abstract
A method and apparatus for processing video signals. According to a preferred embodiment, a video processor is provided, and a video camera interfaced with with the video processor is provided. The video camera supplies video frames to the video processor, and comprises an automatic exposure setting mechanism for automatically updating at least one video exposure parameter before transmitting a next video frame to the video processor. The video camera enables or disables the automatic exposure setting mechanism in response to a strobe signal. It is determined whether to intra-frame encode or to difference encode the next video frame. The video processor transmits a strobe signal to the video camera in accordance with this determination to control the automatic exposure setting mechanism of the video camera.
