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.

A color conversion information generating apparatus includes the following elements. A specific color value obtaining unit obtains a specific color value of a device-dependent color space. A first color element value obtaining unit obtains a first color element value of a device-independent color space by converting the specific color value in accordance with color reproduction characteristics of a display device displaying an image of a subject. A second color element value obtaining unit obtains a second color element value of the device-independent color space by converting a colorimetric value of a color sample which approximates to the specific color value on the basis of a reference value. A generating unit generates, if the first color element value approximates to the second color element value, color conversion information for converting plural color values of the device-dependent color space into plural color values of the device-independent color space.

A measurement position determination apparatus includes a creation unit, a measurement unit, and a determination unit. The creation unit creates display image data for displaying a reference image and a comparison image on a display screen. The reference image includes one achromatic image, and the comparison image is formed by arranging two or more images including a chromatic image. The measurement unit measures the reference image and the comparison image in a sub-area on the display screen. The reference image and the comparison image are displayed on the display screen in accordance with the display image data. The determination unit determines a measurement position of the measurement unit on the display screen in accordance with measurement results obtained by measurement of the reference image and the comparison image using the measurement unit.

In an image processing device, first to third color values are acquired. The first color value is a color value of a specific pixel in a first image obtained by photographing a subject illuminated by a photographic light source. The second color value is a color value of a pixel corresponding to the specific pixel in a second image obtained by photographing the subject not illuminated by the photographic light source. The third color value expresses a luminance closer to that of the first color value than the second color value, and a chroma closer to that of the second color value than the first color value. For a third image generated from the first and second images, a setting unit sets the color value of a pixel corresponding to the specific pixel in the third image to the third color value.

An apparatus for setting a display device includes a target value obtainer, a measured value obtainer, and a determiner. The target value obtainer acquires a target value of a display setting including color temperature and brightness for a display device configured to display an image. The measured value obtainer acquires a measured value of display characteristics including the color temperature and the brightness in each of multiple states specific to the display device, from the display device for which the display setting is sequentially changed to the multiple states. The determiner determines a setting value in the display setting including the color temperature and the brightness from among the multiple states, on the basis of the target value and multiple measured values acquired by the measured value obtainer.
