Title:
PHOTOELECTRIC CONVERSION DEVICE, IMAGE READING DEVICE, AND IMAGE FORMING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/159122
Kind Code:
A1
Abstract:
Provided is a photoelectric conversion device comprising: a pixel array which is provided with a linear array including a plurality of pixels disposed linearly; and memory circuits which are each provided with a memory cell. Each pixel is connected, one-to-one, to a memory cell of the memory circuits. Each pixel alternatingly outputs, to the memory cell corresponding to such pixel, the following: a photoelectric conversion value indicating the voltage generated in accordance with the volume of light incident on the pixel; and a reset value indicating the reference charge of such pixel. Each memory cell temporarily stores a reset value and a photoelectric conversion value output from the pixel corresponding to such memory cell. Each memory circuit outputs, in an order which is determined in advance, the photoelectric conversion value and the reset value stored in each of the plurality of memory cells of such memory circuit.
