Image display apparatus and image display method

摘要

An image display apparatus that displays an image on the basis of input image signals corresponding to sub-pixels forming one pixel includes a shift-amount storing unit that stores shift amounts of display positions of the sub-pixels relative to given reference positions in a display image, an image-signal correcting unit that corrects the input image signals according to the shift amounts, and an image display unit that displays an image on the basis of the image signals corrected by the image-signal correcting unit.

主权项

1. A projector comprising:
a projecting unit configured to project a first image of a first color and a second image of a second color; a storing unit configured to store first information indicating displacement of the second image relative to the first image at a first position, and second information indicating displacement of the second image relative to the first image at a second position; and an image-signal correcting unit configured to correct image signals of the second image according to the first information and the second information to reduce the displacement of the second image, wherein
the projecting unit projects a third image of a third color,the storing unit stores information indicating displacement of the third image relative to the first image, andthe image-signal correcting unit corrects image signals of the third image according to the information indicating displacement of the third image to reduce the displacement of the third image.
