A color correction apparatus including a memory for storing a plurality of combinations of basic colors, each of the combinations of basic colors being obtained by combining a plurality of basic colors. Weighting information storage is provided for storing predetermined mixing ratios of the plurality of basic colors for intermediate colors to be obtained. A calculator is provided for calculating color image data corresponding to the input color image data by processing the combination of basic colors in relation to the mixing ratios.

Method and apparatus for correcting the color of a printed image

An image-scanning apparatus for inputting image data to an image processing device. The apparatus includes an image document holding cassette for holding an image document, a document holder stacker for storing the image document holding cassettes therein, and supplying the image document holding cassette into a scanner, the scanner for irradiating the image document located on a document supporting table and inputting the image data from the irradiated image document with an input sensor through a magnification mechanism, the magnification mechanism for changing the magnification of the image document at said input sensor so that the magnification of the image data is changed, and the document supporting table being capable of changing the angle of the image document to the scanner so that the angle of the image data is changed.
