Patent ID: 8723893

Claim:
A color conversion apparatus for performing color conversion processing on an image, the color conversion apparatus comprising: a display device that is configured to display a first display image, the display image being a chromatic original image; input position obtaining processing circuitry for obtaining a first input position that is associated with a position selected by a user within the first display image; hue obtaining processing circuitry for obtaining a first hue of the first display image corresponding to the first input position obtained by the input position obtaining processing circuitry; conversion target range setting processing circuitry for setting a first conversion target hue range having the first hue obtained by the hue obtaining processing circuitry at a center thereof; and color conversion processing circuitry for changing at least one of saturation, brightness, and hue with respect to each one of a plurality of pixels of the first display image which has a hue within the first conversion target hue range so as to be close to a first conversion target hue, wherein the display device is further configured to output a resultant image based on the changed first display image, wherein the input position obtaining processing circuitry further obtains a second input position specified by the user within the resultant image while the resultant image is displayed on the display device, wherein the hue obtaining processing circuitry further determines a second hue that corresponds to the second input position within the first display image, the second hue being different from a corresponding hue in the displayed resultant image at the second input position, wherein the conversion target range setting processing circuitry determines a second hue range with the second hue at a center thereof, wherein the color conversion processing circuitry creates a new resultant image by updating each pixel of the first display image that has a hue within the second hue range so as to be close to a second conversion target hue, wherein the display device is further configured to output the new resultant image.
