Input Picture DCT Quantization Huffman Coding Quantization Table Huffman Coding Table JPEG Data Library DTC (Discrete Cosine Transform): Each pixel component converted into the frequency domain by two dimension operation Quantization: Divide and round DTC coefficient on quantization table (Non-reversable) Huffman Coding: The most probable data in a quantized result assigned to fewer bits. Note) The created quantization table and Huffman table are taken in into the compressed JPEG data. (Note) YCbCr Format (Note ) Fig8 : JPEG Encode Processing
