Provides an image decoding method, the method includes: using the following equation to represent each pixel in the current image bits to adjust at least a weighted value, the weighted value is to have and includes a pixel in the previous image restoration in each block to block the value weighted pixel value of each block is similar to the the value of pixel operation value; and by using with the pixels included in previous image restoration in each block to block the pixel value of each block is similar to the pixel value multiplied by the weighted adjusted value and weighted other adjusted values and the results of the multiplication, to restore the predicted pixel values of the blocks' W1 '= W1, W2 = W2, O1 = O1' 2 (N-M), O2 '= O2 2 (N-M), wherein W1 and W2' that will be used in the weighted multiplication of the adjusted value, W1 and W2 represent a weighted adjustment the value of The 'O1' and ` O2 'represent the adjusted weighted values that will be added to the result of multiplication, O1 and O2 indicate the weighted values before adjustment, N represents the number of bits, and M stands for constants.

【技术保护点】
一种图像解码方法,该方法包括:用以下的等式适应于表示当前图像的每个像素的比特数来调整至少一个加权值,该加权值是要对具有与包括在恢复的先前图像中的各块中所需块的像素值类似的像素值的各块的像素值操作的加权值;以及通过使用具有与包括在恢复的先前图像中的各块中所需块的像素值类似的像素值的各块的像素值乘以调整后的加权值,并且将其他调整后的加权值与该相乘的结果相加,来恢复所需块的预测像素值,W↓[1]′=W↓[1]W↓[2]′=W↓[2]O↓[1]′=O↓[1]·2↑[(N-M)]O↓[2]′=O↓[2]·2↑[(N-M)]其中W↓[1]′和W↓[2]′表示将用在相乘中的调整后的加权值 ...
