Abstract
A picture data encoding apparatus includes a target bit amount determining part for calculating a target bit amount for each block according to a bit rate and a number of blocks to be converted; and a bit amount adjusting part for reducing a bit amount for each block to the target bit amount by means of reducing the bit amount for each code by converting run level information for each code into lower run level information.

A picture data encoding apparatus comprising:
- a target bit amount determining means for calculating a target bit amount for each block according to a bit rate and a number of blocks to be converted;
- a bit amount adjusting means for reducing a bit amount for each block to the target bit amount by means of reducing the bit amount for each code by converting run level information for each code into lower run level information.
A picture data encoding apparatus comprising:
- a target bit amount determining means for calculating a target bit amount for each macro block according to a bit rate and a number of macro blocks to be converted;
- a bit amount adjusting means for reducing a bit amount for each macro block to the target bit amount by means of reducing a bit amount for each code by converting run level information for each code into lower run level information.
