  • Patent number: 5070355
    Abstract: A camera capable of identifying photographing conditions causative of red-eye effect making the eyes of human pictures in a flash-photographed picture come out red, and recording the identified photographing conditions in an external memory provided on a film cartridge loaded thereon. The camera recognizes the possibility of occurrence of red-eye effect on the basis of the focal length of the camera lens, the object distance, the distance between the optical axis of the camera lens and the light source of the flash light device and the object brightness. When the photographing conditions are identified to be causative of red-eye effect, a warning is displayed and flash photographing is forbidden.

  • Patent number: 5055865
    Abstract: A flashlight photographing device wherein the possibility of missing a shutter chance is minimized, a shutter speed can be set appropriately upon trailing shutter blind synchronized photographing, and an interval of time is minimized until a subsequent photographing operation is permitted. The flashlight includes a plurality of flash devices which are controlled such that one of them which has been charged up at the earliest is caused to emit flashlight. After the charged voltage of a main capacitor of one of the flash devices becomes higher than a second predetermined value but lower than a first predetermined value at which the flash device can operate to emit light, operation of an automatic focusing motor or a film winding motor of a camera is started. When trailing shutter blind synchronized photographing is to be performed in an exposure mode wherein a shutter speed is to be automatically set, exposure of the camera is controlled in accordance with a predetermined exposure time as in bulb exposure.
