Abstract: A method as well as a system to measure melanopic irradiance in a physical environment are provided. A camera is used to capture a panoramic image, which is calibrated to tristimulus values, and used with the spectral power distribution of the light sources to derive the melanopic dose rate.

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: For each colour, the method comprises the following steps :
- converting the first set of colour coordinates (R 0 ,G 0 ,B 0 ) R representing this colour into a first set of visual tristimulus values (X 0 ,Y 0 ,Z 0 ) representing said colour as perceived by a first observer when displayed using a first set of primaries,
- converting said first set of visual tristimulus values (X 0 ,Y 0 ,Z 0 ) into a second set of visual tristimulus values (X i ,Y i , Z i ) representing the same colour as perceived by a second observer,
- converting said second set of visual tristimulus values (X i ,Y i , Z i ) into a second set of colour coordinates (R i ,G i ,B i ) C representing said colour as perceived by said second observer when displayed using a second set of primaries.
