Image reading device, image forming device, and image reading method

Abstract

To make it possible to use a light receiving element array having a different pixel pitch for an image reading device without redesigning an optical system.SOLUTION: An image reading device includes: a light receiving element array including a plurality of light receiving elements that are arranged in a main scanning direction and perform photoelectric conversion for each pixel; a plurality of AD conversion units that are provided in each of the plurality of light receiving elements and convert each of analog data photoelectrically converted by the plurality of light receiving elements into digital data in parallel; a conversion output unit that converts the digital data converted in parallel by the plurality of AD conversion units into image data that is serial data in the main scanning direction and outputs the image data; and a resolution conversion unit that converts a resolution of the image data output by the conversion output unit.SELECTED DRAWING: Figure 2
