Abstract: Provided is a photographing apparatus having both a phase difference auto-focusing function and a contrast auto-focusing function. Provided is an auxiliary light projector capable of projecting auxiliary light of a pattern suitable for the photographing apparatus. An auxiliary light projector and a photographing apparatus including the auxiliary light projector according to an embodiment of the present disclosure may reduce an auto-focusing time with respect to an object and improve reliability of an auto-focusing function.
