Claim 2:
3. A control method 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 method comprising:
a correction step of generating 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
a projection control step of projecting a corrected image based on the corrected image data to the projection object by inputting the corrected image data generated in the correction step into the display portion,
wherein in the correction step, when a region in which a pixel value is zero is present in an end part of the input image data, the first reduction rate is controlled based on a size of the region.
