A motion vector detecting method includes a target image reading step of reading a target image from a target image storing section, a reference image reading step of reading image data having the same size as that of the target image and, in addition, at least one or more packing units of extra image data from a reference image storing section, a correlation degree calculating step of calculating a degree of correlation between the target image and a plurality of reference blocks, where each reference block is a block of image data having the same size of that of the target image within the image data read out in the reference image reading step, and the reference blocks have locations different from each other.
