Depth sensor and method of operating the same

Abstract

Provided is a depth sensor which includes a pixel and a row driver that controls the pixel, the pixel including a first tap, a second tap, a third tap, and a fourth tap, an overflow transistor, and a photoelectric conversion device. Each of the first tap, the second tap, the third tap, and the fourth tap includes a photo transistor, a transfer transistor, and a readout circuit. In a first integration period of a global mode, the row driver activates a second photo gate signal controlling the photo transistor of the second tap and a third photo gate signal controlling the photo transistor of the third tap. In a second integration period of the global mode, the row driver activates a first photo gate signal controlling the photo transistor of the first tap and a fourth photo gate signal controlling the photo transistor of the fourth tap.
