Abstract

The invention discloses a chromaticity measuring device and a chromaticity measuring method. The measuring device comprises a micro-reflector module, an image acquisition module and a control module, the image acquisition module comprises a plurality of image acquisition units, each image acquisition unit comprises a filtering element and a sensor, and the control module controls the micro-reflector module to have various mirror surface deflection angles. The light emitted by a measurement target has various different reflection paths when entering the micro-reflector module, an image acquisition unit is arranged on each reflection path, and the reflected light enters the sensor after passing through the light filtering element. The device has the advantages of short measurement time and simple structure.

Description

technical field [0001] The invention belongs to the technical field of chromaticity measurement, and more specifically relates to a chromaticity measurement device and method. Background technique [0002] Colorimeters are widely used in textiles, dyeing and printing, display panels and other fields to evaluate whether the color characterization of products is normal. If the display needs to display yellow, then the instrument and equipment are required to measure whether the color coordinates of its actual display are yellow. [0003] Colorimeters are mainly divided into two types, one is a midpoint colorimeter, and the other is an imaging colorimeter. A spot colorimeter measures only one spot, while an imaging colorimeter measures color information for the entire luminous area. The current colorimeter scheme is to use the filter that conforms to the CIE standard tristimulus value response curve for measurement, including at least 3 filters, namely CIE X filter, CIE Y fil...
