PURPOSE: To directly drive an imaging unit and perform many processes at the same time by leading out a signal which is suitable to drive an imaging unit provided to sample a video signal in the video processor system.

CONSTITUTION: An analog signal is inputted to the input terminal 2 of the video processor system and digitized by an A/D converter 4, and a demultiplexer 6 distributes digital signal samples to two output terminals corresponding to predetermined allotment. A video processor unit 8 performs the 1st processing of one output of the multiplexer 6 and supplies the processing result to video processor units 10 and 12, and the unit 10 processes the output of the unit 12. The output of this unit 10 is processed by a video processor unit 14 which communicates with a field memory 16, video processor units 18 and 20 process the output of the unit 14 and the other output of the multiplexer 16, and they are controlled by a system controller 20.
