Image coding apparatus and image coding method |
| 摘要 |
A bit counter (214) counts the codes included in one transmission unit. An importance judging section (217) divides the code quantity counted by the bit counter (214) by the number of coding macroblocks included in one transmission unit to calculate an average code quantity per coding macroblock. A threshold comparing section (220) compares the average code quantity with a threshold calculated from the frame rate and the bit rate to determine the importance of the corresponding transmission unit. |
