Abstract: The disclosure is directed to techniques for gamut mapping with modified black point compensation (BPC). The gamut mapping techniques promote well-distributed tone compression so that substantial loss of detail in highlight and shadow regions can be avoided. The gamut mapping techniques may be particularly useful in converting rich saturated images, such as RGB photographs, for presentation as much less saturated output, such as typical newsprint. Other example applications include conversion of CMYK Specifications for Web Offset Printing (SWOP) printing to CMYK Specifications for Newsprint Advertising Production (SNAP) newsprint, and conversion of RGB photos with camera profiling software to CMYK for all types of printing.
Abstract translation: 本公开涉及具有改进的黑点补偿（BPC）的色域映射的技术。 色域映射技术促进了良好分布的色调压缩，从而可以避免高光和阴影区域的细节大量损失。 色域映射技术在转换丰富的饱和图像（例如RGB照片）时可能特别有用，用于呈现不如饱和的输出（例如典型的新闻纸）。 其他示例应用包括将用于Web偏移打印（SWOP）打印的CMYK规范转换为CMYK新闻广告制作（SNAP）新闻纸规范，以及将RGB照片与相机分析软件转换为CMYK进行各种打印。

Abstract: The invention is directed to various calibration techniques for calibrating an imagining device such as a display device, a printer, or a scanner. The techniques may involve characterizing the imaging device with a device model such that an average error between expected outputs determined from the device model and measured outputs of the imaging device is on the order of an expected error, and adjusting image rendering on the imaging device to achieve a target behavior. The invention can achieve a balance between analytical behavior of the imaging device and measured output. In this manner, adjustments to image rendering may be more likely to improve color accuracy and less likely to overcompensate for errors that are expected.

Abstract: A method of performing color conversion between profiles includes comparing two sets of measured and reference data for at least one device corresponding to one of the profiles used in the color conversion, the data from the two sets of measured and reference data correspond to the same device values and are indicative of differences in behavior between a current state of the device and a reference state of the device in which at least one member of the set includes more than one non-zero value of colorants. And performing one-dimensional corrections to one of the profiles in order to account for the differences between the measured and reference data sets prior to performing color conversion.

Abstract: A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Color conversions are calculated by reducing differences between the respective sets of device-independent color values. Based on these color conversions, a color map is constructed that describes a relationship between the color imaging systems.

Abstract: Characterizing a color imaging system involves generating color values representing colors of output samples of the color imaging system. The color values are converted into a device-independent color coordinate system using an adjustable white reference vector and a black reference vector. The white reference vector is calculated using the black reference vector. Color values can be transformed between color imaging systems using the device-independent color coordinate system.
