Abstract: An image processing device comprises an image sensor including unit groups comprising a reference group and a conversion group each including pixels and color filters, and is configured to generate image data using the pixels, and an image signal processor which is configured to calculate a hash of the image data, and to select a filter corresponding to the hash to perform filtering, wherein the image signal processor includes a pixel index converter which is configured to convert indexes of the pixels based on a positional relationship between the pixels, a pixel property converter which is configured to convert the properties of the pixels and to convert the hash before conversion, and a filter coefficient converter which is configured to convert filter coefficients of the pixels based on the respective converted pixel index and the respective converted pixel property.

Abstract: Provided are a method and apparatus for encoding/decoding video. The method and apparatus of the present invention involve generating a first prediction block for a block to be decoded, calculating a filter coefficient on the basis of the block adjacent to the first prediction block, and performing filtering on the first prediction block using the filter coefficient so as to generate a second prediction block if information relating to the performance of filtering indicates that filtering should be performed. According to the present invention, accuracy in video prediction and encoding performance are improved.
