摘要:
A flash case, in which a flash is provided, is automatically moved to an up position, when a user selects a flash mode in a state where the flash case is at a down position, when a user begins to forcibly raise the flash case by hand in a state where the flash case is at the down position, or when the flash case is at the down position in a state where a photometric operation starts in an auto-flash mode. The flash case is automatically moved to the down position, when an external force is added to the flash case at the up position.

A camera system includes a camera body including a photometering device and an external operating device, and a photographing lens which is detachably attached to the camera body, the photographing lens including an aperture setting device for selecting an auto aperture setting and at least one fixed aperture setting. A full-aperture photometering operation is performed when the aperture setting device is positioned at the auto aperture setting, and a stop-down photometering operation is performed in response to an operation of the external operating device when the aperture setting device is positioned at the fixed aperture setting.

A uniform flash-emission controller which controls an intensity of a light emission of a flashtube, the uniform flash-emission controller includes an IGBT which causes the flashtube to emit a rapid series of short flash pulses; an IGBT controller which switches the IGBT ON and OFF so as to maintain the intensity at a substantially constant level; and a latch for holding an ON state and an OFF state of the IGBT until a predetermined period of time elapses from a time the IGBT controller switches the IGBT ON and OFF, respectively.

A camera has a viewfinder that forms a subject image to be observed, a multipoint auto-focus adjuster that focuses the subject image on the basis of multiple focus points defined on the subject image, a superimposer that superimposes an indicator mark on a position of a given focus point, and a focus point luminance detector that detects a luminance of the position. Then, the superimposer superimposes the indicator mark such that a brightness of the indicator mark increases as the luminance of the position increases.

A camera includes a built-in flash and a controller for controlling the camera. The controller includes different photographic modes; an auto-exposure-mode selecting mode in which an appropriate photographic mode is automatically selected from the different photographic modes based on photographic conditions, the controller allowing the built-in flash to discharge automatically in the selected appropriate photographic mode when the built-in flash discharges at a most appropriate time of exposure; and a flash-prohibiting/auto-exposure-mode selecting mode in which an appropriate photographic mode is automatically selected from the different photographic modes based on photographic conditions, the controller prohibiting the built-in flash from discharging automatically in the selected appropriate photographic mode at a time of exposure. The controller selects either the auto-exposure-mode selecting mode or the flash-prohibiting/auto-exposure-mode selecting mode in response to an operation of the manual operation member.
摘要:
A flash photography system includes a camera body, a main flash device and at least one sub-flash device, wherein the main flash device emits at least one low flash emission serving as a main-flash emission command signal to transmit the main-flash emission command signal to the sub-flash device, the sub-flash device emitting a flash emission in accordance with the main-flash emission command signal. The flash photography system includes a designating device for designating a flash emission mode of a main-flash emission, and a command device which activates the main flash device to emit the low flash emission serving as the main-flash emission command signal to transmit the main-flash emission command signal to the sub-flash device in a manner corresponding to the designated flash emission mode.

A flash photography system having a camera body and external flash devices includes a designating device for designating a sync flash mode for a main flash emission; a first pre-flash emission mode in which the external flash devices are activated to emit a preliminary flash emission at the same time; a second pre-flash emission mode in which the plurality of external flash devices are activated to emit the preliminary flash emission in a predetermined order; a pre-flash emission mode selecting device which selects the first or second pre-flash emission mode in accordance with the designated sync flash mode; and a pre-flash emission command device which transmits a command signal to the external flash devices to emit the preliminary flash emission in the first or second pre-flash emission mode.

A flash photography system includes a first photometering device including a multi-segment photometering sensor having a plurality of zone sensors for measuring a pre-flash emission; a second photometering device including a single-segment direct photometering sensor for measuring a main flash emission; a weighting device which assigns a weighting factor to an output of each of the plurality of zone sensors; a calculation device which calculates a correction value based on each photometering value and the weighting factor of each zone sensor of the first photometering device, wherein an appropriate receiving light amount of the second photometering device is calculated in order to attain a compensation exposure for the main flash emission based on the correction value; and a controller which terminates the main flash emission after the light amount measured by the second photometering device reaches the appropriate receiving light amount.

A setting apparatus for a camera includes a first switch having a plurality of stop positions; a second switch; and a shutter speed setting device which can select a desired shutter speed from a plurality of shutter speeds set at predetermined steps in accordance with the stop positions of the first switch. The shutter speed setting device can modify the shutter speed (which has been selected via the stop positions of the first switch) by a step smaller than the predetermined steps via the operation of the second switch.
