Abstract
A projection device converts input image data into light and includes a correction control unit that calculates a correction amount used for eliminating a geometric distortion occurring in a projection image according to a projection direction based on a projection angle and a view angle and determines a cut out range including also an area other than an area of the image data after the geometric distortion correction estimated according to the correction amount, and a correction unit that generates cut out image data acquired by cutting out an area of the cut out range from the input image data and performs a geometric distortion correction for the cut out image data based on the correction amount.
