Embodiment Construction
[0037] The present invention calculates the Nyquist frequency limit area of each primary color sub-pixel arrangement based on the characteristics of the diversity of the R, G, B primary color sub-pixel arrangement of the flat panel display device, and designs a set of R, G, B primary color anti-colors based on this The aliasing filter achieves the purpose of reducing or even eliminating color aliasing introduced by sub-pixel sampling while maintaining high perceptual resolution of the image.
[0038] The present invention first applies corresponding anti-color aliasing filtering to the primary image R, G, and B primary color components, and then performs sub-pixel sampling on the filtered image according to the spatial position structure of the two-dimensional sub-pixel arrangement of the display device. Without changing any physical properties, the visual perception resolution of the flat panel display device is improved at a lower cost, and the super-resolution display of the ...
