ABSTRACT:
A semiconductor substrate is formed by integrating, on a semiconductor substrate, a plurality of photosensitive pixels producing signal charges corresponding to a quantity of an incident light. A shift register responsive to a pulse input from the external generates a predetermined control pulse. A plurality of charge/voltage conversion elements are provided in correspondence with the plurality of photosensitive pixels, respectively, and an element-shared output line is provided for the external output of the plurality of charge/voltage conversion elements. The charge/voltage conversion elements respond to a predetermined control pulse generated from the shift register to detect quantities of integration of signal charges generated from corresponding photosensitive pixels and zero reference levels of the quantity of integration, to convert these detected values into voltages to sequentially output them to the element-shared output line.
