In an output section (11d) of an image sensor (11), information charges are discharged from a capacitance at a reset clock phir1, which is twice the period of a horizontal clock phih, and the information charges for two pixels are accumulated in the capacitance. In two steps, a sample-and-hold circuit (14) inputs an image signal Y0(t) that is output from the output section (11d) and outputs an image signal Y1(t) in which a period representing the information charge for one pixel and a period representing the information charges for two pixels alternately repeat. By taking the difference between the value of the period representing the information charges of two pixels and the value of the period representing the information charge of one pixel in the image signal Y1(t), the information charge of each pixel can be individually determined.
