More Information
Summary:A photoelectric conversion device includes a pixel array including one or more linear array, each including plural linearly-arranged pixels; and plural memory circuits, each including plural memory cells. The plural pixels in the pixel array are connected one-to-one to the plural memory cells of the plural memory circuits. Each of the plural pixels alternately outputs a photoelectric conversion value indicating an electric voltage generated in accordance with a light amount of an incident light entering the pixel, and a reset value indicating a reference charge of the pixel, to the memory cell corresponding to the pixel. Each of the plural memory cells temporarily stores the photoelectric conversion value and the reset value output from the pixel corresponding to the memory cell. Each of the plural memory circuits outputs the photoelectric conversion values and the reset values stored in the plural memory cells of the memory circuit, in a predetermined order.
