Abstract
The number of gradation levels to be obtained after lossy-compressed data corresponding to a predetermined number of gradation levels is expanded and gradation conversion is performed is determined in such a manner that the number of gradation levels is determined to be a first number of gradation levels in a case where the degree of compression when the data to be processed is compressed in lossy compression is more than a first threshold value, and the number of gradation levels is determined to be a second number of gradation levels in a case where the degree of compression is less than or equal to the first threshold value, the first number of gradation levels being smaller than the second number of gradation levels.
