Abstract
An image sensor includes; a pixel array including at an auto focusing (AF) pixel and an AF adjacent pixel, which is adjacent to the AF pixel and is configured to share a floating diffusion region with the AF pixel; and a row driver configured to control the pixel array, wherein a first end of a photo diode included in the AF pixel is connected to a first transmission transistor, and a second end of the photo diode included in the AF pixel is connected to a ground through a first signal line, and wherein a first end of a photo diode included in the AF adjacent pixel is connected to a second transmission transistor, and a second end of the photo diode included in the AF adjacent pixel is connected to the row driver through a second signal line.
