ABSTRACT:
A holding unit holds a plurality of types of white balance adjustment color data with respect to colors of the plurality of projection surfaces. A projection control unit causes a projection unit to simultaneously project patterns having a plurality of colors based on the plurality of types of held color data, upon dividing the patterns into areas configured to be selected for each pattern. A selection control unit causes a designation unit to select a pattern which is whitest from the patterns having the plurality of projected colors. When a given pattern is selected from the patterns having the plurality of colors projected, a color data acquiring unit acquires color data corresponding to the selected pattern from the plurality of types of held color data. A color correction unit performs color correction of an image to be projected.
