Abstract:
1. An image capture and transmission system comprising: first and second imaging devices; first means for generating a timing signal; a common drive circuit for driving the first and second imaging devices at equal timings determined by the timing signal generated by the first means; a first signal processor for converting an output signal of the first imaging device into first digital video data corresponding to a frame; a second signal processor for converting an output signal of the second imaging device into second digital video data corresponding to a frame; second means for setting at least one changeable effective region, having a size smaller than that of a frame, in every frame presented by the first digital video data and the second digital video data, selecting portions of the first digital video data and the second digital video data placed in the effective region in every frame, and processing only the selected portions of the first digital video data and the second digital video data into a stream of packets; and third means for transmitting the packet stream generated by the second means.
