Abstract: An image sensor according to an example embodiment concepts includes a pixel array including pixels, and each of the pixels includes photoelectric conversion elements. The photoelectric conversion elements independently operating to detect a phase difference. The image sensor further includes a control circuit configured to independently control exposure times of each of the photoelectric conversion elements included in each of the pixels.
