1. An image processing device, comprising: an imaging unit configured to obtain an input image; a recognition unit configured to recognize a first object in the input image by using a registered image of the first object stored in the image processing device; an image correcting unit configured to correct a luminance of the first object to be equal to a luminance of the registered image; a detection unit configured to detect an overlapping area in the input image where another object is overlapping with the first object based on the corrected luminance of the first object and the luminance of the registered image, and generate overlapped position information representing the overlapping area; a control unit configured to control a display of an icon at an area other than the overlapping area in the input image based on the overlapped position information; and a command issuing unit configured to issue a command corresponding to the icon, wherein the imaging unit, the recognition unit, the image correcting unit, the detection unit, the control unit, and the command issuing unit are each implemented via at least one processor.
