Abstract: A depth sensor and a 3D camera include a macro pixel that provides an output signal when light is received and a programmable concurrent detector (PCD) circuit that compares an electric signal provided by the macro pixel with a number of concurrence (NC) and determines a necessity of providing the output signal of the macro pixel. In addition, the depth sensor and the 3D camera may include a controller that measures a dark count of the macro pixel, changes the number of concurrence (NC) of the macro pixel, based on the dark count, and controls noise of the macro pixel. In addition, the depth sensor and the 3D camera may control the noise of the macro pixel, based on an external light count which is a noise signal generated due to the external light.
