摘要

The capturing device (1) has a control unit (7), a sensor cell field (2) comprising optical sensor cells i.e. complementary metal oxide semiconductor sensor cells, and a test signal producing device for producing analog test signals. A test cell unit (4) comprises test sensor cells, which detect the analog test signals. The test signal producing device comprises a light source (8), and the test signals comprise electric analog signals and light signals that are produced by the light source.
