摘要： PROBLEM TO BE SOLVED: To provide a density determination method, an image forming apparatus and an image processing system wherein density of a design image constituted of a latent image and a background image can be automatically and optimally determined. SOLUTION: A test sheet constituted of a plurality of latent image patches and a plurality of background image patches is output. Subsequently, the luminance, the density, and the reflection density of each of the patches are obtained from image data obtained by reading this test sheet. Then, an optimal combination of a latent image patch and a background image patch is selected according to the obtained values. Finally, density signal values used to generate the selected patches are set as density signal values to generate a latent image and a background image. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an image-processing method for making clear expression of chromatic characters or the like in an original by preventing the difference of output density for each hue, when expressing the chromatic component in the original in specified colors. SOLUTION: Concerning the image processing method, with which chromatic signals in input signals are expressed in specified colors, while using a density converting means for converting inputted color image data to density signals, and achromatic signals are expressed with achromatic components. The mixing rate of color agents to be used for expressing the specified colors is found, an existent masking coefficient is operated on the basis of the found mixing rate, a new coefficient for reproducing the specified colors is calculated, discrete data to be used for expressing the specified colors are calculated from the provided new coefficient by masking operation, and remaining discrete data are changed, while using one part of the calculated discrete data.

摘要： PROBLEM TO BE SOLVED: To provide an automatic substrate level detection method with high accuracy and less color variance that can be realized with a small memory capacity and in a short processing time. SOLUTION: A histogram denoting appearance frequency of each signal level by each channel of an input image signal is created and a substrate level is determined by taking into account a sum of frequency of peak of the histogram and frequency around the peak. Further, conditions for substrate level detection are independently provided to the cases when an input image is a color image and when the input image is a black/white image, respectively.

摘要： An image processing apparatus which can determine the image quality of code data in consideration of the print characteristics of an output device (copying machine or printer) is provided. A code data input unit (201) inputs code data to be added to an image. A print precision data input unit (204) inputs print precision data indicating the print precision of the code data by a printing device. An image quality determination unit (205) determines, based on the code data and the print precision data, the image quality when the printing device prints the code data.
