Abstract: An electronic device is provided. The electronic device includes a processor configured to obtain a first image of an external object, generate a first color image and a second color image by using the first image, identify a difference in first spread level between a display object of the first color image and the display object of the second color image, determine a first on-focus position of a lens w based on the difference in first spread level, move the lens in a direction corresponding to the first on-focus position, obtain a second image of the external object, determine a second on-focus position of the lens based on a difference in second spread level between the external object contained in the first image and the external object contained in the second image, and move the lens to the second on-focus position.

Abstract: An electronic device of the disclosure may include a camera module including a lens assembly, a reflector for changing a field of view, a Hall sensor for identifying a position of the reflector, and a first memory for storing a first correction value for correcting shading by the lens assembly, a second memory for storing reflector shading correction, and a processor. The processor may obtain a first image frame by driving the camera module, obtain first Hall data corresponding to the position of the reflector through the Hall sensor while the first image frame is obtained through the camera module, obtain the first correction value from the first memory, obtain a second correction value corresponding to the first Hall data among the reflector shading correction values from the second memory, and perform shading correction on the first image frame based on the first correction value and the second correction value.
