Abstract: Polychromatic light is directed at the surface of a live tooth and color data of light reflected therefrom is recorded, multiplied by the stored power distribution of a first standard illuminant and converted to three tristimulus values. Such values are compared with color values of a first group of stored color dental shades, and if a match occurs within a given tolerance, an indication of the nature of the recipe is produced. A second level search may be carried out against a substantially larger group of stored dental shades in the event of a no-match condition resulting from the first search. Excellent lifelike reproduction of the patient's tooth is enhanced by checking for least metamerism by operating upon the measured data with other illumination standards and selecting the best match under all lighting conditions. Additionally, a translucency factor is calculated, and employed to reduce the opacity of the inner opaque layer of the recipe which would otherwise be indicated should the patient's tooth not have a high degree of translucency. The calculation of a fluorescence factor also enhances excellent reproduction of the live tooth, and is employed to indicate the addition of a fluorescent ingredient to the final recipe.
Abstract translation: 多色光指向活牙的表面，并记录从其反射的光的颜色数据乘以第一标准光源的存储功率分布并转换为三个三刺激值。 将这些值与存储的彩色牙科阴影的第一组的颜色值进行比较，并且如果在给定的公差内发生匹配，则产生配方的性质的指示。 在第一次搜索产生的不匹配条件的情况下，可以针对大量存储的牙科阴影进行第二级搜索。 通过使用其他照明标准操作测量数据并在所有照明条件下选择最佳匹配来检查患者牙齿的极好的逼真的再现。 另外，计算半透明因子，并且用于减少食谱的内不透明层的不透明度，否则如果患者的牙齿不具有高度的半透明度，则不透明度。 荧光因子的计算也提高了活牙的优异繁殖，并且用于指示在最终配方中添加荧光成分。

Abstract: Systems, apparatuses, and methods for performing color channel correlation detection are disclosed. A compression engine performs a color channel transform on an original set of pixel data to generate a channel transformed set of pixel data. An analysis unit determines whether to compress the channel transformed set of pixel data or the original set of pixel data based on performing a comparison of the two sets of pixel data. In one scenario, the channel transformed set of pixel data is generated by calculating the difference between a first pixel component and a second pixel component for each pixel of the set of pixel data. The difference is then compared to the original first pixel component for each pixel. If the difference is less than or equal to the original for a threshold number of pixels, then the analysis unit decides to apply the color channel transform prior to compression.

Abstract: The invention relates to a system and a method for ascertaining a color recipe which produces a color product with a specified hue after an application onto a specified substrate using a specified application method. The method has the steps of: a) providing a database with a plurality of data sets, b) specifying a target application method, a target substrate, and a desired target hue by means of a user, c) searching the database using a computer program, and d) when at least one suitable database has been found in step c), displaying the information stored in the at least one data set, said information relating to the color recipe, wherein at least one of the data sets also comprises information on at least one reference hue, a reference application method, and a reference substrate. The reference hue is produced when the color recipe to which information contained in the data set relates is applied onto the reference substrate using the reference application method, and the reference application method differs from the application method to which the information contained in the data set relates and/or the reference substrate differs from the substrate to which information contained in the data set relates.

Abstract: The present invention relates to an apparatus for correcting a dye mixing ratio, the apparatus including a memory, and a processor connected to the memory, wherein, upon receiving a dyeing order including a first computer color matching (CCM) colorimetric value requested by a client, the processor uses at least one of the first CCM colorimetric value, a currently selected dye mixing ratio, a second CCM colorimetric value measured in a dyeing process, fabric characteristic data, and dye characteristic data and corrects the dye mixing ratio so that deviation between the first CCM colorimetric value and the second CCM colorimetric value is minimized.

Abstract: An image forming apparatus includes circuitry. The circuitry extracts a colorimetric area from an image formation area based on designation according to an operation by a user, the image formation area in which an image as a print target is to be formed. The circuitry calculates a color difference between a first page and a second page subsequent to the first page based on a colorimetric value in the extracted colorimetric area and to determine whether to continue printing according to the calculated color difference.
