    摘要: A wireless light amplifying strobe system appropriately regulates the commencement and cessation of each strobe's light emission to enable the radiation intensity of the light emissions to be accurately set. For example, a wireless light-amplifying system has a strobe that is attached to a camera (the primary strobe) and a strobe that is separated from the first strobe (the auxiliary strobe). The primary strobe repeatedly emits a low-intensity flash of light, and the auxiliary strobe detects the emission of light from the primary strobe and repeatedly emits a fixed, low-intensity flash of light upon each emission of light from the primary strobe. The camera measures the light that is reflected from the subject being photographed, which is illuminated by both strobes, with a photometer circuit that passes through the photographic lens. When the proper exposure has been reached, the primary strobe's light emission ceases. When the primary strobe stops emitting light, the auxiliary strobe no longer detects the emission of light from the primary strobe, and automatically ceases its own light emission.

    摘要: A camera system includes a camera having a focal plane shutter and an electronic flash device cooperable with the camera. The flash device, which emits light repetitively, has two operating modes. In a first mode, a light emission start signal is synchronized with the start of the exposure of a film exposure area by a leading curtain of the shutter, and a light emission stop signal is synchronized with the end of the exposure of the film exposure area by a trailing curtain of the shutter. In a second mode, the light emission start signal is synchronized with the full exposure of the film exposure area by the leading curtain, and the light emission stop signal is synchronized with the start of shielding of the film exposure area by the trailing curtain.
