CAMERA MODULE AND OPERATING METHOD OF CAMERA MODULE

A camera module includes pixels each including first to fourth sub-pixels, a row driver connected to the pixels through row lines, an analog-to-digital conversion circuit connected to the pixels through column lines and converting signals of the column lines into digital values, and a logic circuit. Each of the first to fourth sub-pixels includes a first region and a second region. Each of the first and second regions includes a photo detector. In response to the row driver activating signals of half or less of the photo detectors included in one pixel among the pixels, the analog-to-digital conversion circuit generates a first signal. The logic circuit generates an auto focus signal based on the first signal.
