We propose two types of video cameras, which extract automatically only oil images. The first type camera consists of two CCDs and passive optical band-pass (BP) filters with different transmission ranges. The second one consists of one CCD and a wavelength-selective filter. The principle of recognition of oil images and analysis of the passive BF filters are described.
