ABSTRACT:
A solid state image sensor drive apparatus in accordance with the present invention enables a solid state image sensor to start integration of photoelectric current in response to an integration clear signal so that electric charges are accumulated to a prescribed level and transferred to a shift register. The accumulated electric charges transferred to the shift register are read out successively based on a transfer signal so that it is supplied to a microcomputer performing various operations. At this time, if a request for interruption is inputted from a load to the microcomputer, the transfer signal supplied to the shift register is stopped and the content of the shift register is not supplied to the microcomputer. When the interruption processing in the microcomputer is completed, the transfer signal is supplied again to the shift register so that transfer of data from the shift register to the microcomputer is restarted.
