Disclosed is a multi-path method of block matching computing for image processing, which comprises: determining a searching pattern with a center pixel point and a plurality of surrounding pixel points to perform a block searching operation; computing a plurality of pixel value differences between the center pixel point and the surrounding points of two continuous frames; and utilizing at least two pixel points with a pixel value difference as the center pixel point to perform the next block searching operation, wherein the pixel difference of the at least two pixel points has a difference less than a predetermined value from a minimum pixel value difference.
