Patent ID: 7616244

Claim:
A photoelectric conversion device comprising: a photoelectric conversion matrix in which a plurality of pixels, each having a photoelectric conversion element and a switching element connected to one electrode of the photoelectric conversion element, are two-dimensionally arranged; a plurality of drive wires connected individually to the switching elements arranged in one direction of the photoelectric conversion matrix; a plurality of signal wires connected individually to the output side of the switching elements arranged in another direction of the photoelectric conversion matrix; a power source unit connected to another electrode of the photoelectric conversion element and having a first power source for applying a first potential to the another electrode and a second power source for applying a second potential which is different from the first potential to the another electrode; control means by which on-pulses are applied to the drive wires, and by which the switching elements connected to the respective drive wires are turned on; wherein the pixels are driven in a photoelectric conversion mode, a signal electric-charge transfer mode, and a refresh mode; wherein, in the photoelectric conversion mode, the power source unit applies the first potential to the another electrode; and wherein, in the refresh mode, the power source unit applies the second potential to the another electrode, and the control means are controlled such that the timing of at least two on-pulses, which are sequentially and consecutively applied to at least two of the drive wires overlap and an end timing of one on-pulse of said at least two on-pulses is different from an end timing of another on-pulse of said at least two on-pulses.
