Abstract:
A color measuring device includes a lighting arrangement for a measurement field of a measurement object to be measured, a pick-up arrangement for detecting the measurement light reflected back from the measurement field and for converting it into corresponding electric signals, an electronic circuit for controlling operation of the color measuring device and for processing and evaluating the electric signals, and a display for displaying measurement results. The lighting arrangement has a lamp ring with three identical lamp groups for illuminating the measurement field from a predefined range of angles of incidence. The pick-up arrangement has a digital camera which creates an image of the measured measurement field. The electronic circuit is designed to switch the light sources of the lamp groups on sequentially, and the camera creates a separate image of the measurement field for every switched-on light source.
