SYSTEM AND METHOD FOR PERFORMING IMAGE DATA CONVERSION USING INTRAPREDICTION MODES

A data conversion system includes an encoding device configured to encode, into a bitstream, pieces of binary data indicating first intra prediction modes for encoding a first image, and a decoding device configured to decode second intra prediction modes for decoding a second image.
