Image processing apparatus, image processing method, and recording medium

An image processing method, comprising the steps of:

• acquiring an input image by an input image acquisition unit;
• acquiring, by a terminal information acquisition unit, terminal information indicating a type of a terminal device that has input the input image;
• acquiring, by an input image determination unit, color gamut determination information from a color gamut information storage unit based on the terminal information acquired by the terminal information acquisition unit, with the color gamut determination information indicating whether a color gamut of a display unit of a terminal device corresponding to the acquired terminal information is a standard color gamut or a non-standard color gamut that is not the standard color gamut and being stored in association with the acquired terminal information, so as to determine, by the input image determination unit, whether the input image is a standard color gamut image of the standard color gamut or a non-standard color gamut image of the non-standard color gamut based on the acquired color gamut determination information;
• and
• converting the input image as determined to be the non-standard color gamut image into an output image suitable for a color gamut of a printing apparatus by a first color conversion unit which acquires color gamut information from the color gamut information storage unit based on the terminal information acquired by the terminal information acquisition unit, with the color gamut information indicating the color gamut of the display unit of the terminal device corresponding to the acquired terminal information and being stored in association with the acquired terminal information, so as to perform color conversion of the input image based on the acquired color gamut information so that the input image printed by the printing apparatus may be equal in color to the input image displayed on the display unit of the terminal device corresponding to the acquired terminal information.
