Abstract: A first area and a second are formed in an image projected by a projector. A standard image plate is placed in a surface on which an image for the first area is projected. A standard image has been drawn on a standard image plate and is displayed in correct colors when white light is projected on the standard image plate. The projector projects white light as the image for the first area. An image for the second area is projected on a projecting surface. A user operates an operating section so that the image in the second area is closer to the standard image. A color correcting section corrects the colors of the image in the second area on the basis of information inputted to the operating section.

Abstract: In a method of improving quality of color images displayed on or produced from a color image device, a user is made to select a color or an object area of an object of user's interest and color correction is conducted using the selected item as a central color of correction to thereby flexibly achieve color correction. The image color correcting device 1 conducts color correction for an input image 2 and supplying an output image to an image display section 3 and includes object selecting means 10 for selecting an object item or an object color as a color correction object from the output image of the image display section 3 and a color correction processing section 11 for calculating a central color of an object item or an object color thus selected and setting the central color as a central color of correction and correcting the central color to thereby correct the output image into a desired color.
