The situation with the metrological assurance of brightness measurements in Ukraine is analyzed. The main regulatory documents for the characterization of lux meters are considered. It was noted, that the components of the uncertainty of brightness d

The history of the issue on creation of uniform color spaces is analyzed. It is noted that the calculations based on the results of spectral measurements do not adequately correspond to the human visual perception. For all existing color spaces, it h

An approach is proposed for an approximate estimate of the relation between the uncertainties of spectral and color measurements. The approach is based on replacing the entire diversity of the spectra with simple models: a constant over all wavelengt
