An electronic device for previewing dual-shot images comprising: a display screen; a first image sensor configured to capture a front image; a second image sensor configured to capture a rear image; an image signal processor configured to perform image processing on images (600, 605, 610) captured by the first and second image sensors (151, 152); a controller configured to: determine if the front image contains a portion of the user as a subject part based on algorithmic recognition of the subject part; if the front image does contain a portion of the user as a subject part, set an area of pixels of interest (610, 620) within the front image, the area of pixels of interest enclosing the portion of the user as the subject part, if the front image does not contain a portion of the user as a subject part, search for an object that has been learned in advance, and set an area of pixels of interest (610, 620) within the front image, the area of pixels of interest enclosing the object that has been learned in advance as the subject part, output from the first image sensor a partial image based on the set area of pixels of interest, create, using the image signal processor, a combined image by overlaying the partial image (610, 620) on the rear image; and display on the display screen the combined image. a display screen; a first image sensor configured to capture a front image; a second image sensor configured to capture a rear image; an image signal processor configured to perform image processing on images (600, 605, 610) captured by the first and second image sensors (151, 152); a controller configured to: determine if the front image contains a portion of the user as a subject part based on algorithmic recognition of the subject part; if the front image does contain a portion of the user as a subject part, set an area of pixels of interest (610, 620) within the front image, the area of pixels of interest enclosing the portion of the user as the subject part, if the front image does not contain a portion of the user as a subject part, search for an object that has been learned in advance, and set an area of pixels of interest (610, 620) within the front image, the area of pixels of interest enclosing the object that has been learned in advance as the subject part, output from the first image sensor a partial image based on the set area of pixels of interest, create, using the image signal processor, a combined image by overlaying the partial image (610, 620) on the rear image; and display on the display screen the combined image. determine if the front image contains a portion of the user as a subject part based on algorithmic recognition of the subject part; if the front image does contain a portion of the user as a subject part, set an area of pixels of interest (610, 620) within the front image, the area of pixels of interest enclosing the portion of the user as the subject part, if the front image does not contain a portion of the user as a subject part, search for an object that has been learned in advance, and set an area of pixels of interest (610, 620) within the front image, the area of pixels of interest enclosing the object that has been learned in advance as the subject part, output from the first image sensor a partial image based on the set area of pixels of interest, create, using the image signal processor, a combined image by overlaying the partial image (610, 620) on the rear image; and display on the display screen the combined image.
