Title:
光学特性測定装置及び画像処理システム
Document Type and Number:
Japanese Patent JP4806738
Kind Code:
B2
Abstract:
To provide an optical characteristic measuring apparatus and an image processing system capable of achieving a function such as BRDF corresponding to multi-band.
The optical characteristic measuring apparatus is provided with a table 20 mounted rotatably to θ1 direction and θ2 direction, an irradiation section 40 for irradiating light to a sample S placed on the table 20, and a camera 50 for taking a photograph of the sample S. The irradiation section 40 is provided with a horizontal arm 41 mounted rotatably to the θ1 direction, an arch arm 43 mounted rotatably to θ3 direction, and a light source section 44 wherein two rotatable turrets having eight color filters respectively are arranged.
