Information processing device and method, program, and information processing system

An information processing system in which a supply-side device transmits image data to an obtaining-side device, and performs color gamut conversion for compressing or enlarging the color gamut of said image data, said supply-side device includes

• supplying means configured to supply said image data to said obtaining-side device,
• and said obtaining-side device includes
• obtaining means configured to obtain said image data supplied from said supply-side device,
• selecting means configured to select a generating method of table information for specifying a non-mapping boundary which is a boundary between a region where the coordinate movement of a pixel to be processed is not performed, and a conversion source region where the coordinate movement of said pixel to be processed is performed, and a mapping limit boundary which is a boundary other than said non-mapping region, of said conversion source region, for each hue, from a plurality of generating methods according to a predetermined condition, with said color gamut conversion,
• table information generating means configured to generate said table information using the method selected from said plurality of generating methods, and
• color gamut conversion means configured to perform the color gamut conversion of said image data using said table information which has been generated.
