Title: Printing control device and image processing device
Inventor: KATSUYAMA KIMITO
IPC: B41J2/525
Filed: 2001-03-13
Abstract: PROBLEM TO BE SOLVED: To print a high quality image by executing optimum background removing irrespective of a characteristic of a color image. SOLUTION: When RGB color image data is converted to CMY gradation data, removing of a background color is executed as follows. First, a background color removing rate is calculated based on a coordinate point in a CMY color solid corresponding to the RGB image data in consideration of a color hue or a chroma of the color image. An optimum background color removing rate is respectively set beforehand to each of edge lines from apexes corresponding to the respective chromas of cyan, magenta, yellow, red, green, blue and white in the CMY color solid to an apex corresponding to black. By interpolating based on the set values, the optimum background color removing rate of the color image data is calculated.  As the removing of the background color is executed by using the rate calculated by the above method, it is possible to execute the optimum removing of the background color corresponding to the color hue or the chroma of the color image so that a high quality color image can be printed. It is possible to execute the removing of the background color at the same time when the color conversion is executed by using a color conversion table in consideration of the above processing.
