Sample`s color values measuring device, has monochrome sensor with channel, whose spectral sensitivity is selected such that light penetrates over entire wavelength area produces measuring signals in channels in image and monochrome sensors

摘要

The device has an image sensor (36) and a monochrome sensor (40), where the image sensor has two channels with different spectral sensitivity. The monochrome sensor has a channel, whose spectral sensitivity is selected in such a manner that light penetrates over an entire wavelength area produces measuring signals in the channels in the image sensor and the monochrome sensor. The image sensor and the monochrome sensor generate two signal values for each wavelength, where the monochrome sensor has an interference filter (38) that has a predetermined spectral permeability.
