Profile adjustment method, profile adjustment program of non-transitory computer readable medium for storing, and profile adjustment system

A non-transitory computer readable medium storing a profile adjustment program adjusting a profile that has been stored in a memory and includes a predefined, correspondent relation between input coordinate values of an input color space and output coordinate values of an output color space, the input color space being one of a first color space and a profile connection space, the output color space being one of the profile connection space and a second connection space, the profile connection space being different from the first and second connection spaces, the profile adjustment program causing a computer to realize:

• accepting from a user setting of a first adjustment point positioned at first coordinates which have first coordinate values in a color space which is one of the first color space, and the second color space, and the profile connection space, and setting of a second adjustment point positioned at second coordinates which have second coordinate values in the color space and are different from the first coordinates;
• after accepting the setting of the first adjustment point and the setting of the second adjustment point in the color space, setting the color space a third adjustment point positioned at third coordinates which have third coordinate values, based on the first and second adjustment points such that the third adjustment point is positioned between the first and second adjustment points in the color space, or setting the third adjustment point in a different color space which is the profile connection space when the color space is the first color space and when the first and second adjustment points are converted to fourth and fifth adjustment points using an input profile defining a correspondent relation between the profile connection space and coordinate values of the first color space, such that the third adjustment point is positioned between the fourth and fifth adjustment points in the different color space;
• generating third adjustment data indicating third degree of adjustment at the third adjustment point based on first adjustment data indicating first degree of adjustment at the first adjustment point and second adjustment data indicating second degree of adjustment at the second adjustment point, the first degree of adjustment including at least one of first target coordinate values to which adjustment is performed from the first coordinate values or a first difference between the first target coordinate values and the first coordinate values, the second degree of adjustment including at least one of second target coordinate values to which adjustment is performed from the second coordinate values or a second difference between the second target coordinate values and the second coordinate values, the third degree of adjustment including at least one of third target coordinate values to which adjustment is performed from the third coordinate values or a third difference between the third target coordinate values and the third coordinate values;
• and
• adjusting the profile by adjusting the input coordinate values or the output coordinate values in the profile using the first adjustment data, the second adjustment data, and the third adjustment data.

A profile adjustment system adjusting a profile that has been stored in a memory and includes a predefined correspondent relation between input coordinate values of an input color space and output coordinate values of an output color space, the input color space being one of a first color space and a profile connection space, the output color space being one of the profile connection space and a second connection space, the profile connection space being different from the first and second connection spaces, the profile adjustment system comprising:

• a processor configured to execute a plurality of units including
• an adjustment point acceptance unit that accepts from a user setting of a first adjustment point positioned at first coordinates which have first coordinate values in a color space which is one of the first color space, and the second color space, and the profile connection space, and setting of a second adjustment point positioned at second coordinates which have second coordinate values in the color space and are different from the first coordinates;
• an adjustment point addition unit that sets in the color space a third adjustment point positioned at third coordinates which have third coordinate values, based on the first and second adjustment points such that the third adjustment point is positioned between the first and second adjustment points in the color space, or setting the third adjustment point in a different color space which is the profile connection space when the color space is the first color space and when the first and second adjustment points are converted to fourth and fifth adjustment points using an input profile defining a correspondent relation between the profile connection space and coordinate values of the first color space, such that the third adjustment point is positioned between the fourth and fifth adjustment points in the different color space, after the adjustment point acceptance unit accepts the setting of the first adjustment point and the setting of the second adjustment point in the color space;
• an adjustment data generation unit that generates third adjustment data indicating third degree of adjustment at the third adjustment point based on first adjustment data indicating first degree of adjustment at the first adjustment point and second adjustment data indicating second degree of adjustment at the second adjustment point, the first degree of adjustment including at least one of first target coordinate values to which adjustment is performed from the first coordinate values or a first difference between the first target coordinate values and the first coordinate values, the second degree of adjustment including at least one of second target coordinate values to which adjustment is performed from the second coordinate values or a second difference between the second target coordinate values and the second coordinate values, the third degree of adjustment including at least one of third target coordinate values to which adjustment is performed from the third coordinate values or a third difference between the third target coordinate values and the third coordinate values;
• and
• a profile adjustment unit that adjusts the profile by adjusting the input coordinate values or the output coordinate values in the profile using the first adjustment data, the second adjustment data, and the third adjustment data.
