    Abstract: An image sensor is provided. The image sensor includes: a plurality of pixels provided in a pixel array; a controller configured to control a first pixel group of the plurality of pixels to have a first exposure integration time and a second pixel group of the plurality of pixels to have a second exposure integration time; and a signal processor configured to generate image data based on digital signals corresponding to pixel signals generated by the pixel array, by performing operations on a first value of the digital signals corresponding to the first pixel group and a second value of the digital signals corresponding to the second pixel group. The first exposure integration time of the first pixel group is independent of illuminance of the image data.
