装置。 The optical image from the object is made incident on the light receiving element through a three-primary color optical filter and separated into three colors, and the light signals of these three colors are processed into color information by a calculation unit via a signal processing unit for each color system. When calibrating a color measuring device that measures color, three color calibration light emitting elements are provided within the field of view of the three primary color optical filters, and only the light from the calibration light emitting elements is used in the three primary color optical filters during calibration mode. The primary color light enters a light receiving element through a filter, and based on the output of this light receiving element, a correction coefficient is determined by a correction calculation in a calculation section.
A color measuring device characterized in that the correction coefficient is added to the output signal for each color system in a measurement mode.
