More Information
Summary:Provided is an image sensor, which includes: a normal pixel outputting a pixel signal; a plurality of dummy pixels each outputting a reset signal; and an analog-to-digital conversion circuit for analog-to-digital conversion of the pixel data using pixel data output from the normal pixel and an average value of reset signals output from the plurality of dummy pixels. Noise of the image sensor can be reduced. 이미지 센서는, 픽셀 신호를 출력하는 노멀 픽셀; 각각 리셋 신호를 출력하는 다수의 더미 픽셀들; 및 상기 노멀 픽셀에서 출력된 픽셀 데이터와 상기 다수의 더미 픽셀들로부터 출력된 리셋 신호들의 평균값을 이용해 상기 픽셀 데이터를 아날로그-디지털 변환하는 아날로그-디지털 변환 회로를 포함할 수 있다.
