Abstract

본 발명은 투사형 화상표시시스템의 화소보정장치에 관한 것으로, 화소보정위치의 지정과 그 화소에 대한 보정량을 결정하는 제어신호입력부(10)와, 그 제어신호입력부(10)에 의해 지정되는 보정화면(28)상에서 보정 대상의 화소에 대한 R/G/B컬러량의 보정을 제어하는 제어부(12), 그 제어부(12)의 제어하에 상기 보정대의 화소에 대한 화소보정화면을 생성하는 OSD처리부(24) 및, 상기 보정화면상에서 상기 제어신호입력부(10)에 의해 보정되는 화소보정량을 화소보정데이터로서 저장하는 보정데이터기억부(26)을 포함하여 구성되어, R/G/B컬러의 기준치로 형성되는 보정화상에 대해 화소보정을 위한 보정화면을 생성하여 화면표시한 상태에서 컬러강도가 열화된 보정화소에 대해 지정되는 컬러보정량을 보정데이터로서 저장하여 화소보정을 수해하도록 된 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pixel correction device of a projection image display system, comprising: a control signal input unit (10) for determining a pixel correction position and a correction amount for the pixel; A control unit 12 for controlling the correction of the R / G / B color amount for the pixel to be corrected on the pixel to be corrected, and an OSD processing unit for generating a pixel correction screen for the pixel of the correction table under the control of the control unit 12 ( 24) and a correction data storage section 26 for storing the pixel correction amount corrected by the control signal input section 10 as pixel correction data on the correction screen, as a reference value of the R / G / B color. Compensation for pixel correction by generating a correction screen for pixel correction on the formed correction image and storing the color correction amount specified for the correction pixel whose color intensity is deteriorated while displaying it on the screen. The.
