摘要

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.

主权项

1. An information processing apparatus comprising:
an acquisition unit configured to acquire information corresponding to a degree of compression of lossy-compressed data to be processed corresponding to a predetermined number of gradation levels; and a determination unit configured to determine, based on information acquired by the acquisition unit, a number of gradation levels to be obtained after the lossy-compressed data corresponding to the predetermined number of gradation levels is expanded and gradation conversion is performed so that the predetermined number of gradation levels of the expanded data is reduced, wherein the determination unit determines the number of gradation levels to be a first number of gradation levels in a case where the degree of compression of the data to be processed is more than a first threshold value, and determines the number of gradation levels to be a second number of gradation levels in a case where the degree of compression of the data to be processed 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.
