発明の名称 (英語) INSPECTION DEVICE AND INSPECTION METHOD USING FUNCTIONAL LIGHT SOURCE, AND FUNCTIONAL LIGHT SOURCE AND DESIGN METHOD THEREFOR
発明の概要(英語)

An inspection device (30) using a functional light source (31), characterized in comprising: an RGB camera (32), which is a measurement device capable of measuring reflected light and outputting measurement values thereof

a functional light source (31) that uses the color white as the color of the light source by selecting a narrowband light source having three or more mutually different peak wavelengths, controlling the conditions of lights emitted by the narrowband light source, and mixing the lights

and an assessment unit (33) for acquiring measurement values of a plurality of portions under inspection when the light reflected from the portions under inspection are measured by the RGB camera (32) while the portions are illuminated by the functional light source (31), and assessing the inspection results on the basis of the measurement values.
