Abstract
The Ninth Color Imaging Conference was held in November, 2001 in Scottsdale, Arizona, U.S.A. Several papers relating color and color images were presented. This report introduces three papers relating projector. The first paper discusses how to make an interactive wall-size display with a combination of projectors. The second paper introduces a practical system of electronic cinema named DLP using a strong light source and DMD (digital micro device), which has many selectively movable high precision mirrors built in a CMOS chip. The third paper discusses color measurement problems of projector system, especially OHP (over head projector), and concludes that color measurement on the screen is necessary for accuracy.
