Abstract

A technology capable of suitably correcting a geometric distortion caused by a shape of a curved surface of a screen or the like and obtaining a suitable image easily viewable for a user is provided. A projector is an image display apparatus configured to project an image onto a screen and includes a projection lens arranged at a first position and a camera arranged at a second position. When the screen has a curved surface, a camera image obtained by capturing a first image projected on the screen by the camera is acquired, and a geometric transformation for correcting a geometric distortion caused by the curved surface seen from a first virtual viewpoint position (virtual viewpoint) is performed for an image to be displayed based on information of the camera image, the first position, and the second position, and a post-transformation image is projected onto the screen.
