Classification: CPC H  G | IPC G  H

Claim 14:
15. An image processing apparatus comprising:
an input frame buffer configured to store an input original frame;
an encoding processor configured to encode the stored original frame;
an output stream buffer configured to output the encoded original frame as an output stream for multiplexing;
a multiplexing processor configured to control the output stream to be multiplexed and recorded on a storage medium;
a local decoding processor configured to output a restored stream by receiving the output stream from the output stream buffer and decoding the output stream;
a restored frame buffer configured to store the output restored stream; and
a machine learning processor configured to collect the input original frame and the restored frame decoded at the local decoding processor and stored at the restored frame buffer, output a parameter based on machine learning of the collected original frame and the collected restored frame, and control the multiplexing processor to transmit the output parameter to the storage medium,
wherein the storage medium extracts an input stream and parameter information by demultiplexing the input stream requested to be stored, generates a restored frame by decoding the extracted input stream, generates an output frame with an improved image quality by applying the extracted parameter information to the restored frame, and stores the generated output stream.
