Abstract
The invention relates to a method of displaying an image of an effect coating having texture and color properties on an electronic display device, using measured color data and measured texture data as input to generate the image, wherein the textured image is displayed with visual color properties which are maintained on a prescribed level independent of possible variations in texture properties.
Claims18
A method of displaying an image of an effect coating having texture and color properties on an electronic display device under the control of a data processing unit, the method comprising generating the image by using measured color data and measured texture data as input for the data processing unit, and displaying the textured image with visual color properties which are maintained on a prescribed level independent of possible variations in texture properties, such that the perceived color is not influenced by the specific texture, wherein the method comprises,
- a) first generating a grayscale image with prescribed texture properties, wherein the texture properties are selected from the group consisting of diffuse coarseness, glint impression, or a combination of these, and
- b) second, converting the generated grayscale textured image into a textured image with prescribed color properties,
- wherein in a) the texture properties are a combination of diffuse coarseness and glint impression, and the diffuse coarseness image is resized by means of an interpolating resize algorithm, the glint impression image is resized by a non-interpolating resize algorithm, and subsequently the resized diffuse coarseness image and glint impression image are combined to a resized grayscale image with prescribed texture properties, and wherein the degree of resizing depends on the viewer's distance to the displayed effect coating.
A system for displaying an image of an effect coating having texture and color properties on an electronic display device, the system comprising an electronic display device under the control of a data processing unit which is configured to use measured color data and measured texture data as input to generate a textured image with visual color properties which are maintained on a prescribed level independent of possible variations in texture properties, such that the perceived color is not influenced by the specific texture, wherein the system is further configured to,
- a) generate a grayscale image with prescribed texture properties, wherein the texture properties are selected from the group consisting of diffuse coarseness, glint impression, or a combination of these, and
- b) convert the generated grayscale textured image into a textured image with prescribed color properties,
- wherein the texture properties in a) are a combination of diffuse coarseness and glint impression, and the diffuse coarseness image is resized by means of an interpolating resize algorithm, the glint impression image is resized by a non-interpolating resize algorithm, and subsequently the resized diffuse coarseness image and glint impression image are combined to a resized grayscale image with prescribed texture properties, and wherein the degree of resizing depends on the viewer's distance to the displayed effect coating.
