Abstract
It is possible to control color light emitted from a projector by using a personal computer, which can specify the chromaticity coordinates of each pixel. Such a system is used as a flexible light source in fields including visual information processing, and computer vision. The DLP (Digital Light Processing) projector consists of a high-speed rotating wheel with four color filters and a set of digital micro-mirrors. Therefore, color control for the DLP projector is not easy compared with the other display devices such as CRT and LCD. This paper proposes a method for controlling color of this projector based on a neural network technique. Moreover we present a method for correcting the emitted radiance on the spatial location of a screen.
