ABSTRACT:
A system for optimizing display colors of a digital light processing projector includes a color analyzer, and a central processing module. The color analyzer is configured for detecting a first image produced by the projector to obtain actual brightness proportions of red, green, and blue light components associated with the first image, and obtaining a color coordinate of the first image at the actual brightness proportions. The central processing module is configured for adjusting the actual brightness proportions to pre-set brightness proportions to form a second image. The color analyzer detects the second image to obtain a color coordinate thereof. The central processing module adjusts the color coordinate of the second image to a pre-set standard color coordinate, and changes the first gamma curve of the projector to a second gamma curve according to the adjusted color coordinate of the second image.
