Abstract: A method and apparatus can include: displaying original images, the original images including a first original image and a second original image; displaying magnification regions overlaid on top of the original images; detecting a positioning user input, the positioning user input identifying first coordinates for a first center point of a first magnification region; calculating second coordinates for a second center point of a second magnification region based on a linear relationship between the location of the first center point within the first original image and the location of the second center point within the second original image; displaying the second magnification region overlaid on the second original image and the second magnification region having the second center point based on the linear relationship; and displaying magnified images including a first magnified image corresponding to the first magnification region and a second magnified image corresponding to the second magnification region.
