PROBLEM TO BE SOLVED: To provide an underwater photographic mechanism, capable of realizing very distinct and exact photography and accurately grasping underwater structure and adhesive matter in non-visual and poor visual underwater areas, where it seems to be difficult to take a photograph by ordinary underwater photography. SOLUTION: The distinct underwater photography is realized by perfectly removing floating suspended matter, existing between a photographing object and a camera lens in the non-visual and poor visual underwater areas by feeding clear water into the housing so as to exchange water in a photographing area separated by a photographic housing. Thus, the very distinct result of photography, which can be useful decision data hereafter, is obtained. COPYRIGHT: (C)2005,JPO&NCIPI
