<p>The device has a lighting arrangement having a measurement field of a measurement object to be measured, and a pick-up arrangement detecting the light reflected from the field and converting the light into electric signals. An electronic circuit controls operation of the device, and evaluates the signals. A display displays measurement results. An imaging sensor e.g. digital camera, creates a separate image of the measurement field for individually switched-on light sources respectively, and forwards associated measurement values of image pixels to an electronic circuit as image data.</p> |
