    摘要： An exposure system for a camera includes a light emitting apparatus for emitting an artificial light toward an object. The light emitting apparatus is capable of selectively emitting a first type of light which flashes instantaneously, and a second type of light which flashes for a prolonged period of time. The intensity is maintained constant during the prolonged period of time. A camera produces a mode signal for switching the light emitting apparatus between a first mode in which the instantaneous flash light is emitted and a second mode in which the prolonged flash light is emitted.

    摘要： In a photographic system for flash photography, the firing current of an electronic flash tube is selectively restricted in accordance with the detection of whether or not the flash light amount necessary for a flash photograph is below a predetermined level prior to the firing of the flash tube for a photographic exposure. A selection is made between a first mode of flash firing with flash tube current flowing through a switching element and a second mode of flash firing with a flash tube current flowing through an impedance device serially connected with the flash tube. Alternatively, a selection can be made between higher or lower voltage levels to which the main flash firing capacitor is charged. The amount of light required from a flash device can be preparatorily identified and when less than a predetermined light output the flash device is caused to select the second mode of flash firing, or alternatively to select the lower level of the voltage charged by the main capacitor. The operation of the flash tube is controlled such that the flash light emission therefrom substantially corresponds to the necessary flash light amount such that a reduction is obtained in the ratio of excessive amount of flash light to the necessary amount of flash light.

    摘要： A flash photography system for a photographic camera and a flash device adapted to be connected thereto with the camera providing an aperture value output for flash light photography and a flash light stop signal obtained from an integrated output of the light reflected from a photographic object to terminate flash light emission when the integrated value reaches a predetermined value. The flash device calculates a maximum photographing distance covered by the flash light for effecting a correct exposure of the photographic object from the maximum flash light value and the aperture value from the camera. The maximum photographing distance is displayed by a suitable display visible to the camera operator.
