Claim Text:
1. An image processing method based on a virtual algorithm, comprising: a) simulating a single subpixel of a practical pixel through a lattice composed of a bivariate normal distribution to obtain a simulation result of the single subpixel including normal distribution parameters; b) establishing a subpixel array of a single color, which contains a repeating group composed of a left side practical pixel and a right side practical pixel, dividing a whole plane into a grid area in which each square in the grid area corresponds to a practical pixel by using the subpixels of the single color as an origin, and selecting the normal distribution parameters through a limiting condition of the subpixel array of the single color; c) calculating integral values of the subpixels of the single color in different squares according to the selected normal distribution parameters to obtain different weight coefficients of the subpixels of the single color at different squares, stacking the subpixels of the single color in different squares, having an effect on the practical pixel, according to different weight coefficients to obtain the strength of the single color of the left side practical pixel and the strength of the single color of the right side practical pixel in the subpixel array of the single color; and d) placing the strengths of three colors of the left side practical pixel into a pixel to obtain the left side virtual pixel corresponding to the position of the left side practical pixel, and placing the strengths of three colors of the right side practical pixel into a pixel to obtain right side virtual pixel corresponding to the position of the right side practical pixel; wherein, the aspect ratio of the single subpixel of the practical pixel is 2:3, and three subpixels constitute two practical pixels.
