Abstract
An image processing coefficient determination method of an image processing system comprising the steps of: PA1 outputting test pattern image data having one or more image areas each containing a specific spatial frequency component by an image output device for preparing an output image, PA1 measuring a spatial frequency characteristic of the output image, and PA1 determining spatial frequency processing coefficients from a relationship between a spatial frequency characteristic of the test pattern image data and the measurement result of the spatial frequency characteristic of the output image.
