Abstract
At least one mode of a group of modes consisting of a photoelectric conversion/accumulation, transfer, hold and read-out mode adapted for image information is controlled by a basic clock signal generated by a central processing unit for driving and controlling an accumulation type photoelectric conversion element. The frequency of the basic clock signal in the read-out mode is made lower than the frequencies of the basic clock signals in the conversion/accumulation, transfer and hold modes. Since the generation and frequency of the basic clock signal are controlled by the software of the CPU provided with no pulse oscillator, the construction of the hardware of the system to which this invention is applied can be simplified. In addition, since the read-out process of the data of the image sensor is performed for every picture element of the entire picture surface and the characteristic value operation with respect to the data of every picture element, the total processing time can be reduced.
