First, the captured data of the IT8.7/4 standardcolor card under color image acquisition equipments, such as scan-ners, are taken as input signals and standard color data that aremeasured by X-rite eye-one is are used as output values, and theBP neural network-based algorithm generates the mapping modelof the current capturing environment. After cutting out these datawhich are abundant chromatic aberration, a number of samplesare selected from the IT8.7/4 standard color card.
