Abstract

Method for the spectrocolorimetric characterisation of capturing devices. The invention consists of a method for spectrocolorimetric characterisation of capturing devices, regardless of the type of colour architecture and the optoelectronic sensor, which allows for spectral sensitivity curves and colour balancing functions. The method is based on experimental measurement of the spectral functions of optoelectronic conversion in a complete manner for the colour channels, thus obtaining the absolute spectral sensitivity curves and the relative sensitivity curves. The colour balancing functions are obtained from the entire scaling of the spectral relative sensitivity curves and the white balance with respect to the equienergetic stimulus.
