An electronic device able to adjust for large differences in skin tones and colors in images acquired includes a first camera module for acquiring a first image, a second camera module for acquiring a depth map, and a processor. The processor analyzes the first image and the depth map, and determines whether a face is detected only by the second camera module and not by the first camera module. If any such face is detected, the processor controls the first camera module to focus on the area of the face detected by the second camera module and acquire a second and further images after light-metering the semi-detected face.
