1. A method for generating metadata, comprising:
dividing a first image having a first resolution into a plurality of image patches;
converting each of the plurality of image patches into an image patch having a second resolution by using a plurality of candidate conversion models, the second resolution being higher than the first resolution;
determining a plurality of quality factors corresponding to the plurality of candidate conversion models for each of the converted image patches;
selecting a conversion model for each image patch from the plurality of candidate conversion models based on the plurality of quality factors and computation load factors of the plurality of candidate conversion models; and
generating the metadata for converting the first image into a second image having the second resolution based on position information of each image patch and the conversion model selected for each image patch.
