A photographing apparatus is disclosed. A photographing apparatus according to one embodiment comprises: a first image sensor; a second image sensor; and at least one processor functionally coupled to the first image sensor and the second image sensor, wherein the at least one processor may be configured to: obtain, by using the first image sensor, a first image which includes a first pixel, a second pixel adjacent to the first pixel, and a third pixel adjacent to the second pixel in an area other than the area in which the second pixel and the first pixel are adjacent; obtain, by using the second image sensor, a second image which includes a fourth pixel associated with the first pixel on the basis of the position thereof, and a fifth pixel adjacent to the fourth pixel and associated with the second pixel on the basis of the position thereof; determine whether a difference in luminance between the first pixel and the second pixel falls within a designated range; and, when the difference in the luminance between the first pixel and the second pixel falls within the designated range, generate color information corresponding to at least one of the first pixel and the second pixel at least on the basis of the color information of the fourth pixel and the color information of the fifth pixel.
