Abstract
In one of the present invention, a scanning control means and a generating means scan an image by part of light-emitting diodes among a plurality of light-emitting diodes, and generate two-dimensional residual image data enlarged from the image. A light-emission control means controls light emission of the plurality of light-emitting diodes by this enlarged two-dimensional residual image data.
