Abstract
The present disclosure relates to extracting correlation parameters between color planes for prediction by extracting optimum correlation parameters between the color planes using neighboring blocks when a prediction screen is generated through the use of the correlation between the color planes in video encoding. The technology includes neighboring block searching unit responsive to a second block of a reconstructed previous plane corresponding to a first block to be encoded of a current plane, for searching for a third block belonging to neighboring blocks of the second block and having smallest difference in pixel value from the second block; correlation parameter calculator for calculating correlation parameters between the third block and a fourth block reconstructed of the current plane and corresponding to the third block, based on the third block and the fourth block, and predictor for predicting the first block based on the second block and calculated correlation parameters.
