Focusing detector for endoscope
专利汇可以提供Focusing detector for endoscope专利检索，专利查询，专利分析的服务。并且PURPOSE:To prevent the effect of out-of-focus or camera shake, by detecting focusing by cutting off observing illumination light after photographing and opening the shutter for exposure when a fixed time elapses after detecting the focusing. CONSTITUTION:An endoscope 1, an adaptor 11 and a camera 12 are set in a body, and then the inserting part 2 of the endoscope 1 is put into a belly wall 9, etc. Then a photographing lens 14 is controlled manually while looking at a viewfinder of a camera 12. Then a release button is pushed, and a control circuit 28 performs the focusing detection by an output signal given from a photodetecting element 18. The signal is transmitted to a light source 8 during the focusing detection, and therefore the observing illumination light is cut off. An informing means is actuated with glowing of a lamp, etc. when a focusing detection signal is applied. Then the shutter is opened to have the electronic flash emission at a time point when the next focusing detection signal is delivered.，下面是Focusing detector for endoscope专利的具体信息内容。
