  • Patent number: 9633461
    Abstract: A system and method is provided for color managing different content objects in at least one source file. In one embodiment of the present invention, the system includes a color management module, a rendering module, an interface (e.g., GUI), and a memory module for storing a plurality of color profiles. The interface allows a user to specify different color profiles and/or parameters for different object types. For example, the user can specify different source color spaces to use for the default source color spaces based upon object type. Similarly, the user can specify different output color spaces to use based upon object type. Finally, software can be used to generate a map that specifies the object type(s) that leads to the creation of each individual pixel in the rasterized output. Parameters (e.g., brightness, contrast, etc.) of individual pixels can then be adjusted based on object type and user-defined, object-based settings.

  • Publication number: 20100208266
    Abstract: One embodiment of a solid-state color-measuring device includes a plurality of photodetectors and a plurality of filters permanently deposited on the photodetectors, where at least one of the filters includes a single colorant layer having a transmission coefficient as a function of wavelength that descends from a maximum value between approximately 445 and 450 nm to fifteen percent of the maximum value between approximately 485 and 495 nm.

  • Patent number: 7420680
    Abstract: A method for determining the optimal colorant thicknesses for integral CIE color-matching filters is provided. According to a computational study, a four band filter of the present invention provides a best approximation to the CIE XYZ color-matching functions with the least cost.

  • Publication number: 20060215162
    Abstract: A tristimulus colorimeter for measuring reflective or transmissive materials is provided. The colorimeter measures a sample under a calibrated light source, receives inputs to detectors, and determines CIE tristimulus values of the same sample as they would occur under a reference light source. The colorimeter includes a calibrated light source and a single silicon chip that includes three or more detectors. Each detector is permanently coated by a different mix of dyes or other colorants that form a wavelength-selective filter. A single silicon chip embodies all the detectors and electronics, with each detector coated over by deposited filter layers.
