ABSTRACT:
In a photosensor system formed of a photosensor array including a plurality of photosensors arranged in a two dimensional direction, the intervals of the reset pulse, read pulse and pre-charge pulse applied to each row of the photosensor array are respectively set equal to the sum of the reset period, the read period, and the pre-charge period. It follows that even where the read processing time of a single screen is shortened by allowing the processing cycles for the rows to partially overlap with each other, the reset period, the pre-charge period and the read period are prevented from being overlapped in time with each other, making it possible to perform the read operation accurately.
