Studies in Signal Processing Method for Liquid Crystal Projector

Abstract

This paper describes signal processing methods for liquid crystal projector. We consider the following items compensated and improved for the realization of high quality image. The optimum system and inter-face for LCD, the CRT's gamma correction and the LCD's characteristic of transmittance for voltage and temperature, the colour reproduction, the uniformity of projection screen brightness. The system for achieving these are composed of the measurement, the calculation, and the digital signal processing circuit.
