摘要： 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.
