Abstract: Various embodiments of the present disclosure relate to an electronic device that combines a plurality of images. The electronic device may include a first camera including a first view angle, a second camera including a second view angle that is smaller than the first view angle, a memory, and a processor, and the processor obtains a first image including a first brightness and corresponding to an external object, using the first camera, obtains a plurality of second images including a second brightness and corresponding to the external object, using the second camera, generates an image that is corrected to include a brightness corresponding to the first brightness, based at least on the plurality of second images including the second brightness, and generates a composite image corresponding to the external object, based at least on at least a part of the first image including the first brightness and at least a part of the corrected image. Also, other embodiments are possible.
