Claim:
An image processing method, comprising: providing an image data, wherein the image data comprises at least one first image section and at least one second image section, and the image data comprises a plurality of sub-pixel data with a same color; providing an image distribution data, wherein the image distribution data records a position of the first image section and a position of the second image section; and performing an encoding step to bury the image distribution data in the image data so as to form a frame data, wherein the encoding step comprises: performing a first gray-level value converting step to convert a gray-level value of the each sub-pixel data located in the first image section into a first color gray-level value; and performing a second gray-level value converting step to convert a gray level value of the each sub-pixel data located in a second image section into a second color gray-level value so as to generate a difference of a lowest bit between the first color gray-level value and the second color gray-level value, and the image distribution data being buried in the difference.
