Abstract
This quantization device includes a processor configured to calculate first costs in a plurality of data length candidates in consideration of the compression ratio and image quality deterioration due to compression of an image. The cost calculation processing is common processing partially performed among the plurality of data length candidates. The processor is configured to perform the common processing for the plurality of data length candidates, execute the distributed processes in parallel, and determine, as an optimal data length, a single data length for which a minimum cost is calculated among the first costs of the plurality of data length candidate.
