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 captured by the first and second image sensors ; 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 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 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 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 captured by the first and second image sensors ; 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 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 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 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 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 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 on the rear image ; and display on the display screen the combined image . <EOS>
