An information processing apparatus includes a unit that obtains one or more pairs, each of which is constituted by images before and after correction, a unit that obtains changes in color, caused by the correction, of points in an image for the one or more pairs, a unit that obtains a distribution of the changes for the obtained pairs, and an extracting unit. When an interval having a frequency equal to or larger than a threshold determined for each interval exists at a distance of a tolerance width or more from an interval having a maximum frequency in the distribution, the extracting unit extracts, as learning data to learn a color change caused by the correction, the changes that are included in the interval having the maximum frequency but are not included in the interval having a frequency equal to or larger than the threshold determined for each interval.

An image processing apparatus includes an acceptance unit and a color conversion property creation unit. The acceptance unit accepts sets of image information each of which is composed of image information of an image before color conversion and image information of an image after color conversion. The color conversion property creation unit creates a color conversion property for color conversion of an image on the basis of pieces of image-capture setting information that are set for image-capture conditions used when the images before color conversion are captured.

An image processing apparatus includes a reception unit and a conversion unit. The reception unit receives as a designated color a color of an image desired to be seeable when irradiated with light at a specific wavelength. The conversion unit converts, when converting image data on an image to be printed into print data, a color value of the designated color received by the reception unit into a color value including a value for outputting a special color material that has absorption properties for the light at the specific wavelength.

An image processing apparatus includes a specifying unit, an extraction unit, and a creation unit. The specifying unit specifies, for one image among a first image before color conversion and a second image after color conversion, an area for which image information is extracted. The extraction unit extracts plural pieces of color conversion information, which are image information about pixels in the area of the one image among the first image and the second image, the area being specified by the specifying unit, and image information about pixels in the other image corresponding to the pixels in the one image. The creation unit creates a color conversion property on the basis of the plural pieces of color conversion information extracted by the extraction unit.

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.

An image adjusting apparatus includes the following elements. A set color temperature obtaining unit obtains a set color temperature which is set when a white image is displayed, in an image display apparatus. A maximum tone value calculator calculates a maximum tone value of a reference color when the displayed white image is changed into a white image corresponding to the set color temperature. A tone characteristic setting unit sets a tone characteristic of the reference color on the basis of the calculated maximum tone value. If the calculated maximum tone value is decreased from a maximum tone value before the set color temperature is set, the tone characteristic setting unit corrects, in a region in which a tone value of an input image signal is equal to or smaller than a predetermined value, the tone characteristic so that a tone value of an output image signal is increased.
