• a photodetector;
• an initial charge input circuit, the initial charge input circuit directly connected to the address line;
• a charge converter, the charge converter comprising a capacitance formed by a metal insulator semiconductor switch diode and adjacent charge accumulating areas, for converting the charge generated by a photodetector signal additionally to the initial charge into photodetector output voltage, the charge converter directly connected to the signal line and the initial charge input circuit;
• a comparator converting the difference between the photodetector output voltage and a reference voltage into a binary cell signal;
• a reading circuit for reading the binary cell signal through the address lines and signal lines;
• a circuit for generating digital codes of the cell signals;
