Abstract
In this paper, we present a new subpixel rendering algorithm considering
adaptively weighting factors of the current and neighboring subpixels for
matrix displays. The proposed method divides gray levels into several bins
computing the absolute color difference between the current subpixel and neighboring
subpixels. Then, it adaptively assigns weighting factors to the current and
neighboring subpixels. In the experiments using test images, the proposed
subpixel rendering algorithm improved the average luminance sharpness by up
to 0.124, when compared to benchmarks methods. For the chrominance blending,
the average peak signal-to-noise ratio (PSNR) of the proposed method was up
to 1.415 dB higher than those of the benchmarks methods.
