Method and apparatus for controlling encoding rate and quantization scales |
摘要 |
A data processing apparatus able to generate encoded data able to give a high quality decoded image, wherein a Q-calculation circuit specifies a bit rate by which the encoded data is decoded at the time of decoding based on encoded data, then the Q-calculation circuit controls quantization scales of a quantization circuit based on the specified bit rate.
