摘要： When an L*a*b* value of a certain color is outside a target color gamut to be converted, it is judged whether the L*a*b* value is located within the range of the color gamut set under a predetermined condition. This set range is a range in which the accuracy is degraded if colors are converted using only a first method, for example, a range in the neighborhood of the color gamut. If a color to be converted is located within the range, colors are converted using a second method. If the L*a*b* value of the color to be converted is outside of the set range, it is converted using the first method until the conversion result is contained within the range Then, the occurrence of both a problem which the first conversion method has for colors in the neighborhood of the color gamut when colors are converted and a problem which the second method has in the conversion of a color far from the color gamut can be suppressed.
摘要翻译：当特定颜色的L * a * b *值在要转换的目标色域之外时，判断L * a * b *值是否位于在预定条件下设定的色域的范围内。该设定范围是如果仅使用第一种方法（例如，色域附近的范围）转换颜色，则精度降低的范围。如果要转换的颜色位于该范围内，则使用第二种方法转换颜色。如果要转换的颜色的L * a * b *值超出设定范围，则使用第一种方法转换，直到转换结果包含在该范围内。然后，出现第一次转换的问题可以抑制颜色转换时的色域附近的颜色，并且可以抑制第二种方法在颜色远离色域的转换中的问题。

摘要： A color converting apparatus and method which accurately converts a color signal in the vicinity of the boundary of a color range of a color reproducing device. This enables dissimilar devices to exchange color images and accurately reproduce colors from the sending device to the receiving device despite different color capabilities of the two devices. This is accomplished by a first color converted result and a second color converted result are stored in a color conversion table. The first color converted result is obtained by converting an input color signal into a color signal that is color-reproducible. The second color converted result is obtained by converting an input color signal into a color signal that is not color-reproducible. In a region outside of the color reproducible range of a printer, a display, or other similar devices, when the relationship of an input color signal is accurately kept, a color signal is accurately performed.

摘要： If all colors of a picture obtained by a first color picture device cannot be outputted from a second color picture device, a plurality of color data which are outside the gamut of the second color picture device and are inside the gamut of the first color picture device are converted so as to preserve correspondence regarding both the lightness value and the saturation value. Furthermore, if, since an equi-hue line has distortion, the tone of a color represented by color data is changed by conversion, the hue angle of the color data is rotated and converted. In picture data, color data for the color of paper or the color of a picture digitally generated have extreme values, and errors occur when the data are converted. In this case, data around the color data in a color conversion table are modified to obtain a desirable conversion result.

摘要： The invention provides a technique regarding color conversion table construction conversion and makes it possible to convert a construction of an originally present color conversion table efficiently at a high speed into another construction which includes least and necessary color data in a uniform distribution so as to facilitate color conversion. The color conversion table construction conversion method includes the data production interval setting step of setting data production intervals in a first color space based on a data dispersion in one of the first color space and a second color space, the data production step of increasing the number of data representative of the corresponding relationships of colors at the thus obtained data production intervals, and the data selection step of selecting some data from either one or both of the data which originally construct the color conversion table and the increased data.

摘要： In a virtual gamut-obtaining step, lightness, saturation, and/or hue angle of the second gamut is converted and an expanded virtual gamut including at least all of the lightness values of the first gamut is obtained. In a color data changing step, for color data which is not included in the virtual gamut in color data of the first gamut, lightness, saturation, and hue angle are changed, thereby obtaining third color data included in the virtual gamut. In a color data forming step, a conversion opposite to the conversion performed to the second gamut in the virtual gamut obtaining step is executed to the third color data, thereby forming second color data.

摘要： In measuring a spectral irradiance distribution of light, light is irradiated to n (natural number) light-transit sections, which respectively have n kinds of given optical characteristic coefficients, and s (natural number) optical sensors, which respectively have s kinds of given spectral sensitivities, receive the light via the n light-transit sections and detects individual responses for the received light. Then a calculating section calculates m (natural number) spectral irradiances for m kinds of wavelengths as a spectral irradiance distribution based on linear formulae established between the optical characteristic coefficients, the spectral sensitivities, (n×s) responses for the light obtained by the s optical sensors, and the spectral irradiance distribution of the light.
