    Abstract: An electronic apparatus is provided. The electronic apparatus includes: a storage configured to store a plurality of filters each corresponding to a plurality of image patterns; and a processor configured to classify an image block including a target pixel and a plurality of surrounding pixels into one of the plurality of image patterns based on a relationship between pixels within the image block and to obtain a final image block in which the target pixel is image-processed by applying at least one filter corresponding to the classified image pattern from among the plurality of filters to the image block, wherein the plurality of filters are obtained by learning, through an artificial intelligence algorithm, a relationship between a plurality of first sample image blocks and a plurality of second sample image blocks corresponding to the plurality of first sample image blocks based on each of the plurality of image patterns.

    Abstract: Provided are an apparatus and method for improving image quality, by generating a first image and a second image, detecting pixels from the second image based on a difference between a value of the at least one second pixel and a value of at least one input pixel from the input image, by comparing the second image to the input image, and changing the value of the at least one input pixel in the input image by using a value of the at least one first pixel in the first image, which is located in a location that corresponds to a location of the detected at least one second pixel in the second image.
