Abstract: A computer-implemented intelligent alignment method for a color sensing device (12) which initially obtains a raw sense value measured by the color sensing device and converts the raw sense value to a tristimulus value (S401). The color sensing device may be calibrated using a known set of colors (S402). Raw readings received from the color sensing device may be mapped to known tristimulus values (S403), and mapped values may be converted to a standard reference illuminant color space (S404). A client-server system may be provided in which a color sensing device and one or more servers collectively execute operations according to the present disclosure.

Abstract: Determination means includes a three-dimensional color distribution data creation section that creates data on wavelength components of R light, G light, and B light from granules in a three-dimensional color space, a Mahalanobis distance interface creation section that partitions the data into a conforming granule cluster area and a nonconforming granule cluster area, a Euclidean distance interface creation section that determines a position of center of gravity of the conforming granule cluster area and a position of center of gravity of the nonconforming granule cluster area to set an interface that allows the positions of center of gravity to lie at a longest distance from each other, a two-dimensional data conversion section that converts into two-dimensional color distribution data by using a line of intersection between the interfaces, and a threshold setting section that creates a closed area by fitting an inertia equivalent ellipse to the nonconforming granule cluster area on the two-dimensional color distribution data and sets a threshold in the closed area.

Abstract: A system and method for identifying primary color chromaticity coordinates of a red, green and blue light sources includes a tristimulus filter the receives the combined light generated by the light sources. The light sources are preferably a group of red, green and blue light emitting diodes. A processor is configured to generate a plurality of test control signals that sets a desired intensity value for each of the red, green and blue LEDs. Based on these test control signals, the system is configured to measure three sets of chromaticity coordinates corresponding to the combined light generated by these red, green and blue LEDs. The processor thereafter calculates the color chromaticity coordinates of the LEDs, based on the measured coordinates of the combined light, and the intensity values of the LEDs, and the intensity values of the combined light. This calculation in accordance with one embodiment of the invention is accomplished by solving a matrix equation. Once the color coordinates of the individual light sources is uniquely calculated, the system measures the intensity values of light for each of the light sources that is necessary to provide a combined light with a desired color chromaticity coordinates. These intensity values can be used in a feedback control circuit to maintain the desired combined light as the LEDs change their characteristics from batch to batch or over time.
