An electronic device according to an embodiment disclosed herein comprises: a display; a camera module disposed below the display; and a processor electrically connected to the display and the camera module. The processor may: acquire a sample frame by using the camera module; identify whether a light source object is included in the sample frame; determine imaging parameters for acquiring multiple frames when the light source object is identified as being included in the sample frame; acquire the multiple frames on the basis of the imaging parameters; generate a synthesized frame by synthesizing the multiple frames; identify attributes of the light source object included in the synthesized frame; and correct the synthesized frame on the basis of the identified attributes.
