1. A method comprising: obtaining a reference image using a first camera disposed on a first side of an electronic device, and identifying an imaged body in the reference image, the reference image displayed on a display screen on the first side of the electronic device; receiving an operator-selected area on the display screen, the operator-selected area designating a position where the imaged body is to appear in a subsequent image acquired using a second camera disposed on an opposite, second side of the electronic device; obtaining image data using the second camera disposed on the second side of the electronic device; identifying the imaged body in the image data; and providing guidance to the operator of the electronic device based on a comparison between positions of the imaged body in the reference image and the image data and a location of the operator-selected area, the guidance notifying the operator how to move the electronic device so that the position of the imaged body in the image data is closer to being spatially aligned with the location of the operator-selected area.
