Claim 5:
6. The correction method for free full-screen splicing as claimed in claim 1, wherein the step of regulating the brightness of the bright/dark block comprises:
accumulating pixel color information data of pixels of n columns or m rows adjacent to the bright/dark block, and calculating a first mean of the pixel color information data of pixels of n columns or m rows adjacent to the bright/dark block;
accumulating pixel color information data of pixels of n columns or m rows at positions adjacent to the pixels of the n columns or the m rows in the bright/dark block, and calculating a second mean of the pixel color information data of pixels of n columns or m rows at positions adjacent to the pixels of the n columns or the m rows in the bright/dark block;
obtaining a regulation coefficient based on a ratio of the first mean to the second mean; and
regulating pixel color information data of each pixel in the bright/dark block based on the regulation coefficient.
