摘要：
Provided are a method and apparatus for encoding and decoding an image. The method of encoding an image includes generating half-tone data by applying patterns specified by each color channel to input data, rearranging the generated half-tone data according to the characteristics of the applied patterns, and predicting the rearranged half-tone data and encoding the predicted half-tone data. Therefore, encoding and decoding can be performed more efficiently and a compression rate can be improved.
