Image sensor including plurality of auto focusing pixel groups

An image sensor comprising:

• a pixel array including a plurality of image pixel groups and an auto focusing (AF) pixel group disposed in a same row, each of the plurality of image pixel groups and the AF pixel group including a plurality of pixels;
• and
• eight of transmission control signal lines and four of mode control signal lines transmitting transmission control signals to the pixel array,
• wherein each of the plurality of image pixel groups and the AF pixel group includes sixteen pixels,
• wherein the sixteen pixels included in each of the plurality of image pixel groups are connected to each of the eight transmission control signal lines by two,
• wherein eight pixels included in the AF pixel group are connected to each of the four mode control signal lines by two,
• wherein each of other eight pixels included in the AF pixel group are configured to be connected to one of the eight transmission control signal lines.
