Publication number: 20140210851Abstract: An image processing apparatus includes an image information transmission unit, a color information acquisition unit, and a conversion relationship creation unit. The image information transmission unit transmits, to a display device, pieces of color-conversion image information representing images used for performing color conversion for the display device, in ascending order of lightness of the images in a predetermined color space. The color information acquisition unit acquires color information of each image that is displayed on the display device in accordance with a corresponding piece of color-conversion image information among the pieces of color-conversion image information that have been transmitted by the image information transmission unit. The conversion relationship creation unit creates, on the basis of the color information that has been acquired by the color information acquisition unit, a conversion relationship for a color of an image to be displayed on the display device.Type: ApplicationFiled: October 18, 2013Publication date: July 31, 2014Applicant: FUJI XEROX CO., LTD.Inventors: Daigo HAMA, Noriko SAKAI, Toshihiro IWAFUCHI, Kazuhiko HORIKAWA, Makoto FUJIO, Chizuru YAMAZAKI
