Patent ID: 8248678

Claim:
A method for creating one-dimensional transforms for a device, the method comprising: selecting at least one device-dependent color space (DDC) color for transformation; determining a motive for creating one-dimensional transforms for the at least one DDC color; associating points from at least one device independent color space (DIC) curve and at least one DDC curve based on the selected DDC colors; creating at least one one-dimensional transform for the selected DDC colors based on the motive and the associated points; wherein determining the motive comprises determining a need for adjusting a response of the device; wherein selecting at least one DDC color for transformation comprises selecting at least three DDC colors; wherein associating points from at least one DIC curve and at least one DDC curve comprises: identifying a DIC curve as a basis for adjusting the device response; and identifying a DDC curve corresponding to the DIC curve by identifying an associated DDC point for each of a selection of points on the DIC curve using a model of an expected response for the device; wherein identifying the DIC curve comprises identifying a neutral DIC curve; and wherein creating the one-dimensional transforms for the selected DDC colors comprises: selecting a first adjustment point on the DIC curve; selecting a first adjustment vector for the adjustment point; determining an adjustment extent along the DIC curve surrounding the adjustment point; identifying a plurality of DDC adjustment vectors for a plurality of DDC adjustment points on the DDC curve based on the DIC adjustment vector, the adjustment extent along the DIC curve and a model of the expected device response; and creating one-dimensional transforms for the selected DDC colors based on the plurality of DDC adjustment vectors for the plurality of DDC adjustment points.
