    Abstract: An image sensor includes a plurality of pixels and a phase select circuit. Each pixel outputs a pixel signal corresponding to a photoelectric signal in response to a photo gate signal. The phase select circuit outputs delay clock signals of different phases from each other to an object pixel in response to different integration times from each other in a frame. The phase select circuit includes a plurality of delay circuit cells corresponding to at least some pixels of the plurality of pixels. Each of the plurality of delay circuit cells generates a delay clock signal of a certain phase difference from any one of a reference clock signal and an output signal of another delay circuit cell according to a logic state of a select signal.
