Abstract: An image sensor comprises a pixel array and an analog-digital conversion unit. The pixel array generates an analog signal by detecting incident light. The analog-digital conversion unit performs sigma-delta analog-digital conversion and cyclic analog-digital conversion for the analog signal in a first operation mode to generate a digital signal, and performs single slope analog-digital conversion for the analog signal in a second operation mode to generate a digital signal. The image sensor can provide images of good quality having a high signal-to-noise ratio in both a still image recording mode and a video recording mode.
