Abstract:
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; a second signal processor for converting an output signal of the second imaging device into second digital video data; second means for processing 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, wherein the second means comprises means for executing a first calculative operation between the first digital video data and the second digital video data, and generating first operation-resultant digital video data, subtracting means for executing a second calculative operation corresponding to subtraction between the first digital video data and the second digital video data, and generating second operation-resultant digital video data, the second calculative operation being different from the first calculative operation, means for compressing the first operation-resultant digital video data into first compression-resultant digital video data, means for compressing the second operation-resultant digital video data into second compression-resultant digital video data, and means for combining the first compression-resultant digital video data and the second compression-resultant digital video data into the packet stream.
