Photoelectric conversion device having two switch elements

摘要

A photoelectric conversion device includes a first output line, a second output line; and a photoelectric conversion cell. The photoelectric conversion cell further includes, a photoelectric conversion element configured to generate an output current corresponding to an intensity of incident light, a first switch element configured to transmit the first output current to the first output line according to a first control signal, and a second switch element configured to transmit the second output current to second output line according to a second control signal. As a result, the photoelectric conversion device can be provided to generate rapidly the image data with wide dynamic range without the need for complex control outside of the photoelectric conversion device.
