Abstract: In one example, a color reference chart for evaluating a chrominance signal of a video image includes a plurality of color samples arranged in an array, wherein the plurality of color samples comprises: a first color sample of a first known, non-neutral hue and saturation and a second color sample of a second known, non-neutral hue and saturation positioned so that at least a portion of the second color sample is directly adjacent to at least a portion of the first color sample, and a barrier of a known neutral color positioned directly adjacent to the plurality of color samples without separating the at least a portion of the second color sample from the at least a portion of the first color sample.

Abstract: In one or more implementations, the apparatus, systems and methods disclosed herein are directed to calibrating a smart phone with an arbitrary phone case for color lookup applications, wherein the calibration process includes obtaining, with the smartphone without the case equipped, a first measurement data set that includes at least one measurement of each of a black, white and grey calibration target; obtaining, with the smartphone with the case equipped, at least three exposure measurements of a white calibration target at least three different exposure times; calculating an optimized exposure time using at least the at least three exposure measurements; obtaining, with the smartphone with the case equipped, a second measurement data set that includes at least one measurement of each of a black, white and grey calibration target at the optimized exposure time; generating fitting parameters from the first and second measurement datasets; and storing the generated fitting parameters and optimized exposure time in at least one of a local or remote data storage device.

Abstract: As described herein, a method has been developed to estimate the gloss of a black or dark sample using a color measurement system. In such a system, when measuring a higher gloss sample, more illumination light reflected from the sample surface will be directed away from the receiving sensor, and thus less signal will be detected. Using a derived sensor-signal to surface-gloss relationship, the surface gloss of a sample can be calculated by applying the measurements of the sample to the signal to gloss relationship to obtain a more accurate gloss measurement of a sample under analysis.

Abstract: A method and a system are provided for obtaining improved spectra recovery results of a measurement of a sample through the use of a calibration matrix obtained from calibration measurement values using at least one illumination source. By calculating the reflectance spectrum of a collection of calibration samples across several rounds of measurements and cascading the results, an improved calibration matrix can be used to convert the sample measurement values to more accurate results.

Abstract: Systems, methods and computer program products for segmenting colors in a sample image comprised of pixels using a processor configured by code executing for selecting at least one color value present within the sample image and for each color selected from the sample image comparing the color values of each pixel of the sample image to the selected color value and averaging the color values of each pixels of the sample image having a color value difference below a pre-determined threshold. The method also includes outputting the average color value as a color value data object; and associating each averaged color value with sample image.

Abstract: A method and a system are provided to measure transmittance or reflectance of a color specimen by using a transformation matrix obtained from the measurement values of a series of known transmittance or reflectance calibration color standards and multiple flashes from different illumination sources. A color spectrum can be determined with reduced error by calculating the reflectance spectra of an object using measurement matrices obtained under at least two illuminants and the transformation matrix.

Abstract: A method has been developed to monitor the aging of an illuminator (such as a lamp) and the interior sphere wall in a sphere-based color measurement instrument. This monitoring process or method is configurable to independently monitor the aging of the illuminator as well as the aging of the interior surface of a color measurement device using standard calibration measurements already present in the color measurement device.

Abstract: In one example, an initial transform is stored for converting wavelength channel responses of a color measurement instrument to color readings. The initial transform is set in-factory by a manufacturer of the color measurement device. A color selection of a sample is subsequently retrieved from a database, where the color selection was made by an end user in response to a color reading by the color measurement instrument using the initial transform. An adjustment to the initial transform is calculated using the color selection. The adjustment is then sent to the color measurement instrument for use in making future color measurements.
