Abstract: PURPOSE: A three-dimensional image sensor and a mobile device including the same are provided to improve a demodulation contrast by emitting surplus photocharges without the need to increase the frequency of a master clock signal which is a base of transmission control signals, thereby reducing depth error. CONSTITUTION: Each depth pixel (100) includes a Photo Detector (PD) (101), Floating Diffusion (FD) regions (104, 105), Transfer Transistors (TX) (102, 103), Reset Transistors (RX) (106, 107), and an overflow transistor (110) which emits surplus photocharges, which are generated outside the unit time determined by the photo detector, to a second power supply terminal if a drive gating signal is applied. If a photocharge transmission section to a first FD region and a photocharge transmission section to a second FD region do not overlap, the logic unit (120) of a readout circuit applies a transmission gating signal to each transfer transistor. If the photocharge transmission sections overlap, the logic unit applies a drive gate signal to the overflow transistor.
