Title:
画像処理装置、画像処理方法及び画像形成装置
Document Type and Number:
Japanese Patent JP4265484
Kind Code:
B2
Abstract:
An image processing apparatus for creating a 3D color information conversion table for converting a color image signal of one signal processing system into a color image signal of the other signal processing system, based on color measurement signals obtained by measuring of a reference color original, and image reading signals obtained by reading the reference color originals, the image processing apparatus including: an interpolation processing unit for obtaining output values of the color measurement signals corresponding to RGB input values on four apexes enclosing a RGB input value of a computation target point; and an extrapolation processing unit for obtaining the output values of the color measurement signal corresponding to RGB input values of three apexes enclosing the RGB input value of the computation target point and to a RGB input value of the computation reference point.
