Summary:Disclosed are an image sensor reducing a channel deviation, and an image processing system including the same. According to the present invention, the image sensor includes: first to m^th pixels individually connected to corresponding column lines among first to m^th (where m is an integer not less than 2) column lines to output a pixel signal (PS1-PSm); first to m^th bias circuits fixing a column line of an unselected pixel among the first to m^th pixels at a bias voltage; and an analogue-digital conversion block converting the pixel signal into a digital signal. Therefore, the present invention is capable of improving the quality of images. 채널 편차를 감소시키는 이미지 센서 및 이를 포함하는 이미지 처리 시스템 이 개시된다. 본 발명에 따른 이미지 센서는 각각이 제1 내지 제m(2이상의 정수) 칼럼 라인들 중 해당 칼럼 라인에 연결되어, 픽셀 신호(PS1~PSm)를 출력하는 제1 내지 제m 픽셀들, 각각이 상기 제1 내지 제m 칼럼 라인들 중 해당 칼럼 라인에 연결되어, 상기 제1 내지 제m 픽셀들 중 선택되지 않는 픽셀의 칼럼 라인을 바이어스 전압으로 고정하는 제1 내지 제m 바이어스 회로, 및 상기 픽셀 신호를 디지털 신호로 변환하는 아날로그-디지털 변환 블록을 포함한다.
