1. An image processing terminal apparatus comprising: an image capture device having a first light-emitting element emitting light from above in a direction substantially perpendicular to a surface of a document when capturing image data of an intended area, a second light-emitting element emitting light in a direction substantially parallel to the surface of the document when capturing a small image area, and an image sensor comprising a first area and a second area, wherein the first area captures a plurality of large image information by optically motion-scanning the document with the first light-emitting element, and the second area captures small image information selected from at least two predetermined areas with respect to the plurality of large image information by optically motion-scanning the document with the second light-emitting element; an image process device configured to calculate relative position coordinates by referring to the small image information captured in the second area of the image sensor in the image capture device; and an output device configured to output the position information of the small image area resulting from the calculation in the image process device and the corresponding large image information.
