Abstract
An image projection apparatus includes an image generation element to form an image using light emitted from a light source, a shift unit to shift a position of the image generation element when a pixel shift mode is set, circuitry to generate, when the pixel shift mode is set, images used for the pixel shift mode based on image data input to the image projection apparatus, perform keystone correction processing to the generated images, and cause the processed images to be projected as the image by reciprocally shifting the position of the image generation element, or to perform, when the pixel shift mode is not set, the keystone correction processing to image data input to the image projection apparatus to generate an image applied with the keystone correction processing, and project the generated image without shifting the position of the image generation element.
