Abstract:
An apparatus for processing a first color image comprising a plurality of pixels each including at least two color components to generate a second color image comprising a plurality of pixels each including at least two color components, resolution of said second image being higher than that of said first color image, said apparatus comprising:blocking means for blocking the first color image so as to generate a block of the first color image, said block including a plurality of pixels;classifying means for classifying the block of the first color image using at least two color components of the same pixel within the block; andpredicting means for predicting the pixel of the second image according to a class classified by said classifying means,wherein said predicting means includes a memory for storing prediction data corresponding to said class, and an image predictor for predicting the pixel of the second color image according to the prediction data and the first color image, andwherein said predicting means predicts the pixel of the second color image according to the prediction data and at least two color components of the same pixel of the first color image.
