Abstract: An exemplary image processing method and apparatus, and an exemplary digital photographing apparatus, may develop and display a screen nail image and a face screen nail image rather than a full resolution image. The screen nail image may be generated using RAW data output from an image sensor, a predetermined face region of the screen nail image may be detected, and the face screen nail image may be generated from the screen nail image using coordinates of the detected face region. Thus, power consumption and processing time delay caused by processing all parts of a full resolution image may be minimized, and a quality of the full resolution image may be conveniently checked. As a result, a user may conveniently select and store an image in high-speed still picture photographing.
