Abstract
An image sensor which has a simple construction, and can read a voltage value, not a current value, based on the quantity of light received by the photo diode, and can read charge of the light sensing elements every block. A plurality of light sensing elements each consisting of a photo diode and a blocking diode, make up a block. A plurality of blocks are arrayed. The blocking diodes are connected to a shift register for transferring a bias voltage thereto. The lead wires from the photo diodes are connected to common signal lines. The common signal lines are respectively connected to load capacitors. Potential caused in each common signal line by the charge stored in the corresponding load capacitor is read out.
