Abstract
An imaging device includes a light source configured to operate by a light control signal having a first duty ratio; a pixel array in which a plurality of pixels are disposed, each of the plurality of pixels including a photodiode for generating electrical charges in response to a light reception signal output by the light source and reflected from a subject, and a pixel circuit for outputting a pixel signal corresponding to electrical charges of the photodiode; and a logic circuit configured to generate raw data for generating a depth image using the pixel signal, wherein the logic circuit inputs a photo control signal having a second duty ratio to the pixel circuit connected to the photodiode in each of the plurality of pixels, and wherein the first duty ratio is not an integer multiple of the second duty ratio.
