Title: COLOR MEASURING DEVICE AND METHOD
Abstract:
In this color measuring device and color measuring method: a measurement opening is illuminated with illuminating light for a prescribed time and with a constant light intensity; reflected light comprising the illuminating light that has been reflected by an object being measured facing the measurement opening is received; an assessment is performed on the basis of a plurality of outputs of the light reception, continuous over time, to assess whether the color measurement is correct or incorrect; and the assessment result is output. By this means, the color measuring device and color measuring method of the present invention can be applied even to a measurement region that has a relatively small surface area, and measurement results having higher repeatability can be obtained in a shorter time.
