  • Patent number: 10999478
    Abstract: An image processing apparatus includes a receiver and a correcting unit. The receiver receives a first read value and a second read value. The first read value indicates a result of reading a first color by a reader from a recording medium in which the first color is applied to a first area in which in-plane density unevenness is confirmable within the recording medium. The second read value indicates a result of reading a second color by the reader. The second color is different from the first color and is applied to a second area that is substantially the same as the first area in a superimposed manner. The correcting unit corrects in-plane density unevenness of the second color applied to the first color in the superimposed manner based on the first read value received by the receiver and the second read value received by the receiver.

  • Patent number: 9940899
    Abstract: 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.

  • Patent number: 9654754
    Abstract: 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.

  • Patent number: 9330616
    Abstract: An automatic correction function determining apparatus includes an output unit and a determining unit. The output unit sequentially outputs a first display image and a second display image to a display. The first display image includes a target area being a colorimetric target and formed of a first image and a non-target area not being a colorimetric target and formed of a second image. The second display image includes the target area formed of the first image and the non-target area formed of a third image different in mean gradation value from the second image. The determining unit determines that an automatic correction function is active on the display, if a colorimetric measurement result of the target area in the first display image displayed on the display is different from a colorimetric measurement result of the target area in the second display image displayed on the display.

  • Patent number: 9177526
    Abstract: 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.
