47.2: Luminance Management for Seamless Multi-Projector Displays



Multi-projector displays exhibit severe luminance variation. Matching luminance at every pixel to the pixel with most limited luminance range leads to severe degradation in the dynamic range of the display, rendering it practically useless. We present a new optimization technique to manage the luminance in a smooth constraint manner to maintain a perceptual seamlessness while improving the dynamic range of the display dramatically.
