Abstract
In this letter, a new subpixel rendering algorithm using the hue-saturation-intensity
(HSI)-based color error analysis is proposed for matrix display devices. The proposed method
converts an RGB input image into a HSI image, which is a color space based on human color
perception, in order to analyze the sampling errors that are caused by subpixel rendering. Then,
it computes the difference between the directionally displaced pixels and selects the direction
with the minimum difference. Finally, the proposed method adaptively assigns weights to current
and neighboring subpixels based on the directional difference. In experiments for various types of
test images, the proposed method enhanced the average luminance sharpness by up to 0.224 and the
average chrominance blending by up to 7.311 dB, as compared to the benchmark methods.
