摘要： A photocurrent corresponding to the intensity of the light from the subject which photocurrent is successively generated at predetermined intervals is converted into a voltage by being logarithmically compressed by a logarithmic compression circuit in a divisional cell of a metering sensor during the preliminary light emission of the flash immediately before the actual shooting. Then, the voltage level is outputted to a controller as an analog metering signal. The controller A/D converts the successively inputted analog metering signal to generate digital data corresponding to the BV value representative of the brightness of the subject under flash light, and stores the digital data into a RAM. Then, the controller calculates a subject distance for determining the light emission amount of the flash in the actual shooting by performing a digital calculation including an integration calculation of the BV values obtained under ambient light and under flash light.

摘要： The oscillating switching element of step-up transformer comprises a dedicated high-frequency FET and is placed between center tap of the primary coil and the ground of the primary circuit. Terminal of the primary coil on the side of the ground is connected to the connection point between xenon tube and the light emission controlling switching element, i.e., an IGBT, via diode. Charge voltage of main capacitor is detected by voltage detection circuit, and when charge voltage is below threshold voltage, controller drives the IGBT at a low frequency, while when charge voltage has exceeded threshold voltage, it drives the FET at a high frequency to charge main capacitor. The charging of main capacitor is made faster and more efficient by changing the switching frequency and by switching the switching element between the IGBT and the FET as charge voltage increases.

摘要： A camera comprising a flash unit attachable to a camera body, a switching device and a control device. The flash unit includes a light emitter switchable between an emission permit state in which the light emitter is projected from a body of the flash device and an emission prohibit state in which the light emitter is retracted into the body. The flash unit further includes a control circuit for selectively placing the light emitter in the emission permit state and the emission prohibit state. A main switch is provided in the camera body to be switchable between a position for permitting a camera operation and a position for prohibiting the camera operation. When the light emitter is placed in the emission permit state when the main switch is switched to the position for permitting the camera operation.
