Patent ID: 8297760

Claim:
An image processing device comprising: an image display apparatus that displays a first color component image and a second color component image such that the first color component image and the second color component image overlap each other; a lens-shift amount acquisition section adapted to acquire an amount of shift of a projection lens of an image display apparatus; an image signal correction section adapted to correct the image signal corresponding to a sub-pixel of a pixel in accordance with the amount of shift acquired by the lens-shift amount acquisition section to correct displacement of the sub-pixel relative to another sub-pixel of the pixel due to the lens-shift; and a non-transitory computer readable memory storing a program enabling the lens-shift amount acquisition section to acquire the amount of shift, and the image signal correction section to correct the image signal, wherein the amount of shift acquired by the lens-shift amount acquisition section corresponds to a displacement of the first color component image relative to the second color component image due to the lens-shift.
