Image processing method and apparatus

An image processing method, comprising:

• upon receiving a mixed image, determining color values of mixed pixels in the mixed image, wherein the mixed image corresponds to a basic color of a color model, and a color value of each of the mixed pixels comprises color components corresponding to the basic color of N mixed sub-pixels in the mixed pixel, and N is a positive integer greater than 1;
• generating a monochrome image corresponding to the basic color according to the color values of the mixed pixels, wherein for N mixed sub-pixels in each of the mixed pixels, N monochrome pixels in the monochrome image corresponding one-by-one to the N mixed sub-pixels are determined according to a pixel-position mapping relation, and color components of the basic color of the N mixed sub-pixels are respectively determined as color values of the N corresponding monochrome pixels;
• and
• displaying the monochrome image by controlling a display component of the field sequential display device;
• wherein the mixed image is generated according to color values of original pixels in an original color image;
• the original color image comprises a first number of original pixels, the mixed image comprises a second number of mixed pixels, and the monochrome image comprises the first number of pixels, wherein the first number is greater than the second number.

An image processing apparatus, comprising one or more processors, and the one or more processors are configured to perform operations comprising:

• determining color values of original pixels in an original color image, wherein each of the original pixels comprises N original sub-pixels corresponding to basic colors of a color model respectively, each color value comprises color components of the basic colors, and N is a positive integer greater than 1;
• generating mixed images corresponding to the basic colors respectively according to the color values of the original pixels, wherein for each of mixed pixels in each of the mixed images corresponding to one of the basic colors, N original pixels corresponding one-by-one to N mixed sub-pixels in the mixed pixel are determined according to a pixel-position mapping relation, and the color components in the color values of the N original pixels are determined as color components corresponding to the N mixed sub-pixels respectively;
• upon generating each mixed image of the mixed images, sending the each mixed image to a field sequential display device according to an image transmission rule consistent with the color model, so that the field sequential display device generates and displays a monochrome image corresponding to the basic color according to the each mixed image;
• wherein the original color image comprises a first number of original pixels, each of the mixed images comprises a second number of mixed pixels, and the monochrome image comprises the first number of pixels, wherein the first number is greater than the second number.
