Abstract

An image sensor is provided. The image sensor includes a pixel array having active pixel sensors arranged in rows and columns; a correlated double sampler that converts sensing signals transferred from pixels sensors selected from the active pixel sensors to correlated double sampling signals and outputs a conversion result by column; and an analog-to-digital converter that converts the correlated double sampling signals corresponding to plural columns to digital signals using a global code. The analog-to-digital converter includes a column shared operator that performs a digital conversion operation on correlated double sampling signals corresponding to two or more columns of the plural columns.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2013-0096568 filed on Aug. 14, 2013 in the Korean Intellectual Property Office, the entire contents of which are hereby incorporated by reference. technical field [0002] Apparatus, apparatus, methods, and articles of manufacture consistent with the present disclosure relate to an image sensor, and more particularly, to an image sensor using a global counter, an analog-to-digital converter, and an analog-to-digital conversion method. Background technique [0003] In recent years, the use of mobile devices, such as smart phones, tablet PCs, digital cameras, MP3 players, e-books, etc., is proliferating. Most mobile devices include one or more image sensors for capturing images. The image sensor may include a Charge Coupled Device (hereinafter, referred to as CCD) image sensor and a CMOS image sensor. [0004] CCD image sensors have less noise than CMOS image sensors. In addition, the picture quali...
