IMAGE PROCESSING DEVICE, PROJECTOR, AND IMAGE PROCESSING METHOD

摘要

An image processing device adapted to correct a keystone distortion of an image projected on a region where a first plane and a second plane intersect with each other at a predetermined angle includes a transformation section adapted to calculate a first coordinate to be referred to in a first coordinate transformation for correcting the keystone distortion and a second coordinate to be referred to in a second coordinate transformation for correcting the keystone distortion, a combination section adapted to generate a composite coordinate obtained by combining the first coordinate and the second coordinate calculated by the transformation section, and a correction section adapted to perform a coordinate transformation for correcting the keystone distortion using the composite coordinate generated by the combination section.
