Patent ID: 7822269

Claim:
A projector color correcting method comprising: a color conversion generation step for generating a color conversion for each of the pixels or blocks of an image projected onto a projection plane based on previously set first color information and second color information on the image projected onto the projection plane; and a color correction step for correcting an input image for colors on a pixel-by-pixel or block-by-block basis using the color conversion; wherein said color conversion generation step comprises: an association step for projecting the image onto the projection plane, and capturing the image to acquire a captured image for establishing an association between pixels or blocks of the image and pixels or blocks of the captured image; a color information acquisition step for acquiring the second color information as color information for each pixel or block of the captured image; and a color conversion calculation step for calculating a color conversion for each pixel or block of the image based on the first color information, the second color information, and said association.
