摘要： Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.

摘要： A brightness colorimeter having a measurement error caused by linearly polarized light, which is corrected, includes: a lens module to which light irradiated from one side is input; a polarization conversion module configured to intersect the light input through the lens module to convert polarization characteristics; a spectral module provided in one unit block to reflect and intersect the light input through the polarization conversion module so as to branch the light in different three directions; filter modules arranged on progress paths of the light branched in different three direction through the spectral module to intersect monochromatic light beams having specific spectra among the light branched in the three directions; and measurement modules arranged to correspond to exit angles of the monochromatic light beams penetrated through the filter modules, to measure at least one of a brightness, a chromaticity, and an error obtained by the monochromatic light beams.

摘要： A method for matching color of a part to be printed in an additive manufacturing process, includes: (a) blending a color formulation, the color formulation including a thermoplastic polymer and at least one colorant; (b) printing a color chip from the color formulation in an additive manufacturing process; (c) at least one of measuring or observing a color of the color chip; (d) comparing the color of the color chip to a color of a reference, wherein the reference represents a color of the part to be printed in an additive manufacturing process; and (e) repeating steps (a) through (d) by blending a new color formulation that more closely matches the color of the reference until the color of the color chip matches the color of the reference within an acceptable variance. A color chip formed in the color matching process is also described.

摘要： Systems and methods for determining a customized cosmetic formulation. In one method, a user is guided to capture an image of a skin region with known lighting and color characteristics, and the image is processed to provide calibrated skin color information. A customized cosmetic formulation is automatically determined for the user based on the calibrated skin color information. In another method, a user is interactively guided through capture of one or more skin region images using a device having an image sensor. The skin region images are processed to provide calibrated skin color information, which is compared to a ground truth data set to identify a set of closest known values in the ground truth data set. A customized cosmetic formulation is automatically determined for the user based on the comparison.

摘要： Apparatus for measuring spectral reflectance of a surface, the apparatus comprising: a chamber comprising a wall formed having an aperture defined by an aperture boundary; a light source mounted to the chamber and having a field of illumination (FOI) configured to intersect the aperture at an illumination intersection; and an optical fiber mounted to the chamber and having a field of view (FOV) configured to intersect the aperture at an imaging intersection; wherein the chamber is configured so that when the aperture is positioned on a surface the chamber substantially prevents light from entering a volume of the chamber.

摘要： A measuring device is a measuring device that performs colorimetry of an evaluation patch formed on a medium and a paper white patch that is a portion exposed by the medium. The measuring device has a light source portion that irradiates the medium with an illumination light, a measurement portion that acquires an amount of light from the medium as a measurement value, a memory that holds a paper white standard value that is a reference measurement value of the paper white patch, and a colorimetry unit that corrects a measurement value of the evaluation patch based on the measurement value of the paper white patch and the paper white standard value. Even in a case where a measurement position is changed, a reflectance of the evaluation patch is accurately calculated and a chromaticity of the evaluation patch can be accurately acquired.

摘要： A method for thermally-sensitive coating analysis of a component includes imaging the coated, exposed component over a range of distinct frequencies as selected by a narrowband variable filter; estimating parameters of non-uniformity correction (NUC) for every pixel at every wavelength; constructing a 2D temperature map on a pixel-by-pixel basis using the non-uniformity correction; and mapping the 2D temperature map to a 3D computer aided design (CAD) model.

摘要： A print system and a method for detecting inline failure of a curing light source of a 3D object printer are disclosed. For example, the print system includes a plurality of printheads, a curing light source, an inline failure detection (IFD) system, a movable member to hold an object, a heat resistant member coupled to the movable member that holds a thermal paper for testing operation of the curing light source and a controller to control movement of the movable member to move the object past the array of printheads, to operate the plurality of printheads to eject the marking material onto the object as the object passes the two-dimensional array of printheads, to operate the curing light source to apply energy to the thermal paper and to cure the marking material, and to operate the IFD system to read the thermal paper to detect a failure of the curing light source.
