Video communication apparatus capable of electronically adjusting the field of view of a video frame

摘要

A video communication apparatus for encoding a video signal representative of a scene being picked up by a video camera and transmitting the encoded signal. The apparatus generates, in response to a synchronizing signal synchronous to the video signal, signals representative of a predetermined pick-up area to be encoded which is smaller than the entire pick-up area being picked up by the video camera, and a signal representative of a position of the predetermined pick-up area in the entire pick-up area. These signals mark the predetermined pick-up area with the entire pick-up area. A memory stores video data associated with either one of the entire pick-up area and the predetermined pick-up area.
