Zusammenfassung:A projection device includes a projection unit including a display element in which pixel lines each formed by pixels arranged in a first direction are arranged in a second direction and an optical system that projects light emitted from the display element and projecting an image based on input image data, a first correction unit for correcting a scale of each line data of the image data that corresponds to each of the pixel lines, a second correction unit for correcting a second-direction scale of each pixel data of the image data after the correction performed by the first correction unit, and an image cutting-out unit for cutting out image data of an area, which is projected from the projection unit, of the image data after the correction performed by the second correction unit and input the image data of the area to the projection unit.
