<p>There is provided a method for automatically set a spatial resolution for an image to be encoded by properties of an image during an encoding process. The method includes the steps of dividing the moving image into blocks and compression encoding the moving image for each of the blocks, decoding an encoded moving image, obtaining a block distortion ratio from a decoded image, and making a resolution decision to select a first resolution lower than a current spatial resolution if the block distortion ratio is greater than a first threshold value or a second resolution higher than the current spatial resolution if the block distortion ratio is smaller than a second threshold value. <IMAGE></p> |
