Power-constrained backlight scaling and contrast enhancement for TFT-LCD displays

Abstract

We propose a novel backlight-scaled contrast enhancement algorithm to maintain the image quality when the backlight of a TFT-LCD display is dimmed for power reduction. First, we derive the transformation function to maintain the perceived luminance and enhance the contrast. Second, we model the perceptual distortion, which describes the information loss due… (More)
