Claim 0:
1. A control device of a projection apparatus that projects an image from a display portion displaying the image to a projection object through an optical system, the control device comprising:
a processor configured to
generate corrected image data by performing correction processing including reduction processing of reducing input image data input into the display portion at a first reduction rate and image shifting processing of shifting a position of color image data of a specific color component included in reduced image data obtained by the reduction processing by a specific amount in a specific direction, the specific amount and the specific direction being predetermined according to the specific color; and
project a corrected image based on the corrected image data to the projection object by inputting the corrected image data generated by the processor into the display portion,
wherein when a region in which a pixel value is zero is present in an end part of the input image data, the processor controls the first reduction rate based on a size of the region.
