IMAGE PROCESSING DEVICE, AND IMAGE PROCESSING METHOD

摘要

The present invention generates a highly-accurate restored image while reducing computation costs by obtaining a similar effect to when the adjacent similarity of restoration patches is taken into consideration. This image processing device is provided with: a provisional restoration image generation means that uses a dictionary for storing at least two sets of data having associated therein a blurred patch and a restoration patch, and that generates a provisional restoration image from restoration patches selected on the basis of a value indicating the degree of similarity between blurred patches and a plurality of input patches generated by partitioning an externally-received input image; a provisional patch generation means that generates provisional patches by partitioning the provisional restoration image; and a restoration means that generates a restored image from restoration patches selected on the basis of the combined value of a value indicating the degree of similarity between the input patches and the blurred patches, and a value indicating the degree of similarity between the provisional patches and the restoration patches.
