Abstract
If an image reproducing apparatus has a device-dependent color space conversion function that converts the color space of processing target image data to a device-dependent color space using a particular color space, (i) reproduction image data is generated by carrying out basic color space conversion to image data for which the color space specified by color space identification information is the standard color space, and (ii) reproduction image data is generated by carrying out device-dependent color space conversion to image data for which the specified color space is the particular color space. If the image reproducing apparatus does not have the device-dependent color conversion function, (i) reproduction image data is generated by carrying out basic color space conversion to image data for which the specified color space is the standard color space, but (ii) a notification indicating that the specified color space is not the standard color space is output where the specified color space is the particular color space.
