Abstract

A display apparatus includes a deforming unit configured to geometrically deform an input image in order to correct a distortion in a projected image obtained when the input image is projected on a projection surface; and a setting unit configured to set parameters of image deformation processing by the deforming unit, wherein the setting unit sets the parameters such that a position of an intersection of diagonal lines of a first projected image obtained when the image before being deformed according to the set parameters is projected on the projection surface is identical to a position of an intersection of diagonal lines of a second projected image obtained when a deformed image, which is an image after being deformed according to the set parameters, is projected on the projection surface.
