  • Patent number: 5754897
    Abstract: A strobe camera with a strobe emission section movable between a first position in which strobe light can be emitted and a second position different from the first position. A strobe state detection unit outputs a first strobe state signal when the strobe emission section is in the first position, and a second strobe state signal when the strobe emission section is in the second position. A camera state detection unit outputs a first camera state signal when the camera is in a photographing-permitted state, and a second camera state signal when the camera is in a photographing-prohibited position. A control unit causes the camera to execute a warning operation when the camera state detection unit outputs the first camera state signal and the strobe state detection unit outputs the second strobe state signal, and causes the camera to stop execution of the warning operation and perform an exposure operation when the first strobe state signal is output instead of the second strobe stage signal.

  • Patent number: 5184170
    Abstract: A photographing light quantity controller for an endoscope is used to control the quantity of illuminating light when a photograph is to be taken through the endoscope. The photographing light quantity controller comprises a light source for supplying light for illuminating an object to the endoscope, and a device for detecting an illuminating condition in an observation state before a photographing operation is initiated. A device is also provided for controlling the brightness of illuminating light that is supplied from the light source to the endoscope during the photographing operation on the basis of a signal that is detected by the device for detecting an illuminating condition in the observation state.
