ABSTRACT:
Apparatus for acquiring both color and glossiness of a sample such as a painted material in order to inspect the quality of their color and glossiness by comparing them with those of another sample. The apparatus mainly consists of a standard light source, chroma sensing means, glossiness sensing means, decision data storing means storing various color and glossiness data together with a computer program, and a CPU for the comparison of data. The apparatus can be used for color reproduction in the automobile industry.
