IMAGE PROCESSING DEVICE, PROJECTION DISPLAY DEVICE, AND IMAGE PROCESSING METHOD
First Claim
1. An image processing device adapted to generate image data of a projection image, which is displayed on a projection target surface using a projection display device, having a color obtained by correcting a color of original data representing an image to be displayed so that the projection image has a desired color, the image processing device comprising:
- a storage section adapted to store a spectral reflectivity of the projection target surface;
a designation section adapted to designate a type of an outside light in an installation environment of the projection target surface;
a correction light determination section adapted to determine a correction light, a reflected light of which on the projection target surface corresponds to a light having a spectral distribution presenting an achromatic color by overlapping a reflected light of the outside light on the projection target surface, using a spectral distribution of the reflected light of the outside light obtained based on the spectral reflectivity and a spectral distribution of the outside light; and
a correction section adapted to generate the image data using the original data and data of a spectral distribution of the correction light.

Abstract
An image processing device generates image data of a projection image displayed on a screen having a color obtained by correcting a color of original data representing an image to be displayed so that the projection image has a desired color. The image processing device includes a storage section adapted to store a spectral reflectivity of the screen, a designation section adapted to designate a type of an outside light in an installation environment of the screen, a correction light determination section adapted to determine a correction light using a spectral distribution of the reflected light obtained based on the spectral reflectivity and a spectral distribution of the outside light, and a color correction section adapted to generate the image data using the original data and data of a spectral distribution of the correction light.

13. An image processing method adapted to generate image data of a projection image, which is displayed on a projection target surface using a projection display device, having a color obtained by correcting a color of original data representing an image to be displayed so that the projection image has a desired color, the image processing method comprising:
-
obtaining a spectral distribution of a reflected light of an outside light in an installation environment of the projection target surface on the projection target surface based on a spectral reflectivity of the projection target surface and a spectral distribution of the outside light; calculating a correction light, a reflected light of which on the projection target surface corresponds to a light having a spectral distribution presenting an achromatic color by overlapping a reflected light of the outside light on the projection target surface; and generating the image data obtained by adding data of the correction light to the original data.
