Methods for selecting resolution with minimum distortion value and devices performing the methods

摘要

A method of operating an image processing according to an example embodiment includes generating a plurality of encoded bitstreams having different resolutions using an original image output from a video source, generating a plurality of restored images corresponding to the plurality of encoded bitstreams, respectively, the plurality of restored images having a same resolution as a first resolution of the original image, and outputting one of the plurality of encoded bitstreams, based on the plurality of restored images and the original image.
