Disclosed is an electronic device configured to generate depth information. The electronic device includes: a memory storing one or more instructions and image data; and at least one processing circuit configured to generate the depth information on the image data by executing the one or more instructions, wherein the at least one processing circuit is further configured to obtain luminance data of the image data, generate absolute depth data for the luminance data by using a first artificial neural network configured to extract disparity features, and generate the depth information based on the absolute depth data.
