  • Patent number: 11968347
    Abstract: An image processing apparatus comprising: a decision unit configured to decide a first color mapping method to a print color gamut for a first partial original based on a pixel value included in the first partial original and the print color gamut of a print unit and decide a second color mapping method to a print color gamut for a second partial original based on a pixel value included in the second partial original and the print color gamut of the print unit; and a color conversion unit configured to perform color conversion of the first partial original by the first color mapping method decided, and perform color conversion of the second partial original by the second color mapping method decided.

  • Publication number: 20240106964
    Abstract: An image processing apparatus obtains image data that is defined as a first color gamut, transforms the image data into image data that is defined as a second color gamut, using color transformation information, and when, as a result of transformation, a first pair of color values included in the image data is transformed into a second pair of color values that have a color difference that is not perceived as different colors, generates second color transformation information such that the first pair of color values is transformed into a third pair of color values that have a color difference that is perceived as different colors as a result of transformation using the second color transformation information. A saturation difference of the third pair of color values is larger than a saturation difference of the second pair of color values.

  • Publication number: 20180297889
    Abstract: Disclosed herein are methods for treating a glass substrate, comprising bringing a surface of the glass substrate into contact with at least one surface treatment agent for a time sufficient to form a coating comprising the at least one surface treatment agent on at least a portion of the surface. Also disclosed herein are glass substrates comprising at least one surface and a coating on at least a portion of the surface, wherein the coated portion of the surface has a contact angle ranging from about 20 degrees to about 95 degrees, and/or a contact angle greater than about 20 degrees after contact with water, and/or a contact angle less than about 10 degrees after wet or dry cleaning of the glass substrate.
