Abstract: A color correction device includes a color conversion section configured to convert an input value of an input color space into an output value of an output color space, a selection section configured to receive selection of one or more color components as target color components from among a plurality of color components used in a printing device, and a correction section configured to corrects a output value. The correction section configured to, when the input value is a first type input value representing a color that does not include the target color component, execute a first correction process that corrects a first type output value corresponding to a first type input value so as to reduce the target color component. The correction section configured to, when the input value is a second type input value within a propagated correction range set around the first type input value in the input color space, a second correction process that corrects a second type output value corresponding to the second type input value in accordance with a position of the second type input value within the propagated correction range.

Abstract: A color conversion information generation device generates one or a plurality of intermediate points located on a first line segment connecting a first coordinate value representing a first color in a first color space and a second coordinate value representing a second color, in such a way that a number of intermediate points included in each of a plurality of reference spaces corresponding to a plurality of reference points is one or fewer. The color conversion information generation device generates modified conversion information in such a way that, when a coordinate value on the first line segment is converted into a coordinate value in a second color space by the modified conversion information, the coordinate value resulting from the conversion reflects one of a first adjustment value, a second adjustment value, and a third adjustment value. The color conversion information generation device generates color conversion information for converting a fourth coordinate value on the first line segment generated based on an operation by a user, into a coordinate value in the second color space, based on the modified conversion information.

Abstract: In an output profile representing a correspondence relationship between device independent coordinate values and second coordinate values in a second device dependent color space, a color conversion table used to convert the device independent coordinate values into the second coordinate values is defined as a first conversion table, and the device independent coordinate values at the adjustment point are defined as to-be-adjusted PCS values. In optimization, an optimization process including an element making provisional color values closer to an adjustment target is executed, the provisional color value being acquired by a conversion, in accordance with the first conversion table, of provisional PCS values resulting from a change in the to-be-adjusted PCS values, thus acquiring an optimal solution for the device independent coordinate values corresponding to the adjustment target.
