Information processing device and method and program

An information processing method comprising:

• determining whether to perform:
• a first gamut conversion processing to convert an image gamut into the target gamut after performing restoring processing to return at least a portion of the image gamut into the state before the gamut conversion, wherein the first gamut conversion processing is performed if the target gamut is wider than the image gamut, or
• a second gamut conversion processing without performing the restoring processing, wherein the second gamut conversion processing is performed if the image gamut is wider than the target gamut, wherein the image gamut is subjected to gamut conversion before the determination by the control unit,
• wherein the image gamut is subjected to the gamut conversion before the determination by the control unit;
• executing the restoring processing according to control by the control unit;
• and
• executing the determined gamut conversion processing according to the determination by the control unit.

A non-transitory computer-readable storage medium having stored thereon, a computer program having at least one code section, the at least one code section being executable by one or more processors for causing a computer to perform steps comprising:

• determining whether to perform:
• a first gamut conversion processing to convert an image gamut into a target gamut after performing restoring processing to return at least a portion of the image gamut into a state before gamut conversion, wherein the first gamut conversion processing is performed if the target gamut is wider than the image gamut, or
• a second gamut conversion processing without performing said restoring processing, wherein the second gamut conversion processing is performed if the image gamut is wider than the target gamut,
• wherein the image gamut is subjected to the gamut conversion before the determination by the control unit;
• executing the restoring processing according to control by the control unit;
• and
• executing the determined gamut conversion processing according to control by the control unit.
