Abstract: Disclosed is an image sensor including a pixel array including a plurality of pixels, each of the pixels including a first photodiode and a second photodiode, each of which outputs a first pixel signal based on a first conversion gain using the second photodiode in a first period, outputs a second pixel signal based on a second conversion gain using the second photodiode in a second period, outputs a third pixel signal based on the first conversion gain using the first photodiode in a third period, and outputs a fourth pixel signal based on the second conversion gain using the first photodiode in a fourth period, an ADC circuit that performs sampling on a reset signal and an image signal of each of the first to fourth pixel signal. A sampling count and the number of sampling bits are adjusted differently from each of the first to fourth period.
