Image processing apparatus, color adjustment system, and non-transitory computer readable medium

A color adjustment system comprising:

• a color conversion apparatus that performs, using a predetermined conversion relationship, color conversion processing on image information used for displaying an image on a display device and that outputs resulting image information to the display device;
• and
• a conversion relationship creation apparatus that creates the conversion relationship used by the color conversion apparatus, the conversion relationship creation apparatus including
• an image information transmission unit that transmits, to the 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,
• a color information acquisition unit that 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, and
• a conversion relationship creation unit that creates, on the basis of the color information that has been acquired by the color information acquisition unit, the conversion relationship.

A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:

• transmitting, 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;
• acquiring 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;
• and
• creating, on the basis of the color information that has been acquired, a conversion relationship for a color of an image to be displayed on the display device.
