    • 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.
    • 保持单元保持关于多个投影表面的颜色的多种类型的白平衡调整颜色数据。 投影控制单元使得投影单元在将图案划分成为每个图案被选择的区域时,基于多种类型的保持的颜色数据同时投影具有多种颜色的图案。 选择控制单元使得指定单元从具有多个投影颜色的图案中选择最白的图案。 当从具有投影的多种颜色的图案中选择给定图案时,颜色数据获取单元从多种类型的保持的颜色数据中获取与所选择的图案相对应的颜色数据。 颜色校正单元执行要投影的图像的颜色校正。
