Luminance-difference-based adaptive subpixel rendering algorithm for matrix displays

This paper presents an adaptive subpixel rendering algorithm that uses the luminance difference between the current subpixel and neighboring subpixels. The proposed method reduces both the color fringing artifact and blurring, thereby enhancing greatly the image quality.

I. Introduction

Subpixel rendering is a technique to control subpixels within a pixel to increase the apparent resolution when the resolution of an input is higher than that of an output. Using this technique, monitors or TVs with the low resolution can display images with the high resolution taken by a digital camera or videos recorded by a camcorder.
