Abstract

A projector includes a moving unit adapted to move positions of at least six correction points, which are included in a correcting image, a reception unit adapted to receive a designation on a value of a parameter representing linearity, a derivation unit adapted to derive a correspondence relationship of the coordinates between and input image and the correcting image using coordinates of the at least six correction points moved by the moving unit, and the parameter having the value designation of which is received by the reception unit, and a processing unit adapted to perform a correction process on the input image based on the correspondence relationship derived by the derivation unit.

First claim

What is claimed is:

1. A projector comprising:
a moving unit adapted to move positions of at least six correction points, which are included in a correcting image;
a reception unit adapted to receive a designation on a value of a parameter representing linearity;
a derivation unit adapted to derive a correspondence relationship of the coordinates between an input image and the correcting image using coordinates of the at least six correction points moved by the moving unit, an…
