Abstract
The present invention is provided with a storage section that holds characteristic data, a predicted output value calculating section that calculates predicted PCS values (X, Y, Z) in a predetermined designated color space, an error calculating section that calculates an error from the difference between the PCS values (X, Y, Z) and the predicted PCS values, a differential coefficient matrix creating section that creates a differential coefficient matrix, an inverse matrix calculating section, a primary-color intensity correction amount calculating section that calculates a corrected primary-color intensity by performing a primary conversion to the difference between the PCS values and the predicted PCS values with an inverse matrix defined as a conversion matrix, and a primary-color intensity correction section that calculates the output primary-color intensity by adding or subtracting to or from a temporal primary-color intensity (IR, IG, IB) the corrected primary-color intensity calculated at the primary-color intensity corrected amount calculating section.
