1. An image encoding apparatus for encoding an image divided into a plurality of blocks, comprising:

  • a quantizer for quantizing data of each block according to quantization information;

    a quantization information generator for generating first quantization information for each block based on at least the amount of codes generated by encoding; and

    a rounding controller for rounding the first quantization information within a set range to generate second quantization information that is smaller in amount than the first quantization information, wherein the second quantization information is used as the quantization information of the quantizer.
