摘要： A photographic flash exposure control system for a camera associated with a flash device. In conformance with a preselected shutter interval, an effective exposure aperture of a diaphragm device is computed by a computing circuit of the system. The total flash energy available from the flash device is automatically controlled in accordance with the luminance of the subject being photographed, to thereby provide correct exposure for complex lighting situations.

摘要： A flash photographic exposure control system for a camera having an electrically timed shutter is provided with an additional electronic or mechanical timing device in combination with an electronic changeover switch responsive to attainment of the threshold level of the flash unit associated therewith. This is done to switch the camera from an automatic daylight exposure range to an automatic flash exposure range in which a particular timed interval suited for flash photography is made by the timing device which is brought into cooperation with the shutter operating means when the changeover switch is actuated, while the intrinsic timing device for the shutter being cut off from the control means for the shutter.

摘要： A voltage detecting means is provided in a flash lamp firing circuit for detecting the attainment of the voltage of a storage capacitor to a satisfactory lamp firing voltage level to assure that a photographic camera associated with the flash lighting unit operates in a flash exposure range switched from a daylight exposure range only when a sufficient voltage is available to fire the lamp at the time of striking of the lamp. In one embodiment, the detecting means comprises two transistorized circuits having output terminals one of which is connected to the gate lead of a SCR in a discharge circuit of the lamp, and another output terminal which is arranged to be connectable to a light-emitting diode of the camera and therefrom connected to the gate lead of an electronic change-over switch for selection of the operating ranges of the camera, the light-emitting diode being arranged to be visible from the outside of the camera so that the operator is immediately aware if the storage capacitor voltage has attained the satisfactory firing level.

摘要： The present invention relates to the flash photographic system for camera which is characterized in that the system presents a safety device for preventing various misoperations generally apt to take place at the time of taking a photograph by using a flash light device. By means of the operation of this device, the shutter time is set at a certain determined time for taking a photograph under flash light with the shutter time setting means at the camera side whereby the flash light photographic mode setting signal can be obtained only when the light device is set at the state ready for flash lighting in such a manner that the camera is capable of taking a photograph under flash light only when this signal is obtained. According to a preferred embodiment in accordance with the present invention, even when the release operation is carried out so that the above mentioned flash light photographic mode setting signal is not obtained, the flash light device does not operate by means of the effect of the safety device so that the camera is automatically set in the state for taking photography under ordinary day light.
