Abstract: An imaging device includes a light source operated by an optical control signal generated using a first reference signal having a first frequency and a second reference signal, having a second frequency different from the first frequency, a plurality of pixels, each of the plurality of pixels including a pixel circuit outputting a pixel signal corresponding to the electrical charge of a photodiode, and a logic circuit configured to generate raw data to generate a depth image, using the pixel signal. The plurality of pixels include first pixels and second pixels, and the logic circuit inputs a first photo control signal, having the first frequency, to the pixel circuit connected to a photodiode in each of the first pixels, and inputs a second photo control signal, having the second frequency, to the pixel circuit connected to a photodiode in each of the second pixels.
