Abstract
The quantization unit calculates the number of bits of location information determined based on the location of a coefficient level to be significant first in order of transmission and included in the image block, calculates the number of value information bits of a coefficient level to be significant, and sets a coefficient level to be significant in which the number of location information bits and the number of value information bits meet a predetermined condition to 0.
