PURPOSE:To obtain color image duplication of high quality by adding a color correction operator consisting of an arbitray function generator, weighting adders and storage means of storing the weights thereof. CONSTITUTION:The inputs 201-203 of an operator 6 are converted to, for example, 9 pieces of function groups 611-619 by a function generator 60. These are defined as f1, f2...fj...f9. Linear adders 61-63 calculate sums of products by using the coefft. values respectively set beforehand in storage devices 64-66 with respect to 9 pieces of the inputs, and generate outputs 601-603, which are defined as y1, y2, y3 respectively. If the inputs 201-203 are defined as x1, x2, x3 respectively and the coeffts. of the devices 64-66 are a1j,-a3j respectively, yi is expressed by the equationI. A color recorder 3 is driven by the y1, y2, y3 and duplicated pictures are recorded in a recording medium 4. The function fj and the coefft. a1j are determined by the prescribed equation and method. Thereby, the color image duplication of high quality is obtained. |
