An EBCOT unit generates an encoding pass from one bitplane to be encoded to another to execute arithmetic coding. In controlling the code volume to a target code volume, a rate controller sums the arithmetic codes in a sequence from the arithmetic code with the highest bit position in the totality of the code blocks of an input picture to the arithmetic code of the lowermost bit, from one bitplane to another or from one encoding pass to another, and halts the summation when the predetermined target code volume is exceeded. | 10-01-2009 |
