Abstract:
1. A conversion data adjustment method comprising the steps of: an acquisition step of acquiring a user instruction for adjusting first conversion data; an adjustment step of adjusting the first conversion data for converting color data of a device independent color space into color data of a device dependent color space, according to the user instruction; an input step of inputting first color data of the device independent color space, the first color data representing a sample image; a first conversion step of converting the first color data into second color data of the device dependent color space by using the adjusted first conversion data; a second conversion step of converting the second color data into third color data of the device independent color space, by using second conversion data for converting color data of the device dependent color space into color data of the device independent color space; a color difference calculation step of calculating a color difference between the first color data and the third color data; a detection step of detecting a portion that the calculated color difference is larger than a predetermined value; a display step of displaying a preview image based on the third color data and notifying the user of the detected portion in the preview image; a storage step of storing the adjusted first conversion data.
