摘要： In a camera having a lens shutter and a focal-plane shutter accomplishing the operations of programed exposure and aperture control, a flash photography changeover device includes a first changeover circuit for setting a lens shutter mode for operating the lens shutter as a programed shutter or a focal-plane shutter mode for controlling the shutter speed by the focal-plane shutter and the aperture by the lens shutter; a first driving device for controlling the programed exposure value and/or the aperture value of the lens shutter; a second driving device for controlling the shutter speed of the focal-plane shutter; a sequence control circuit for controlling the operating timings of the two driving devices; a setting circuit for selecting and setting automatic exposures with a natural light and a flash light; and a coercive changeover circuit for setting the lens shutter mode irrespective of the setting of the first changeover circuit when the setting circuit is set to the automatic exposure with the flash light. The setting circuit and the coercive changeover circuit may be replaced by a determining circuit for detecting and determining a limit shutter speed at which the focal-plane shutter is synchronized with the flash light; and a coercive changeover circuit for setting the lens shutter mode irrespective of the setting of the first changeover circuit for setting the shutter mode, when the determining circuit determines that the shutter speed exceeds the limit speed.

摘要： A camera has a back cover movable between a closed state and an open state to enable a film case to be installed in and removed from the camera. A detector detects the transition of the cover between the closed state and the open state. A data register stores control data, and a control circuit receives the control data from the data register for controlling operation of the camera. The control data is transferred temporarily from the data register to an EEPROM when the back cover makes the transition from the closed state to the open state. The control data is then transferred back from the EEPROM to the data register when the back cover makes the transition from the open state to the closed state. By temporarily storing the control data in an EEPROM when the back cover is open, and transferring the control data from the EEPROM back to the data register when the back cover is closed, the adverse effects of static electricity, external noise or resetting of the control circuit are prevented from disrupting the operation of the camera.

摘要： A camera has a shutter which may also constitute a diaphragm. In a multi-flash mode the shutter selectively has a maximum aperture at an onset or at the end of the time base. The flash occurs in synchronism with a shutter waveform shaped by this aperture area and a time base element. In a second embodiment, a second diaphragm setting circuit is provided, in diaphragm priority photography, for computing a measurement value of a distance to a subject and a second diaphragm value from the guide number during an emission of flashed light. The diaphragm is set to the computed second diaphragm value, ad an electronic flash is energized with a desired aperture area. The diaphragm is set to an initial value to effect the photography at a time other than during the emission of flashed light. A timing circuit may be provided for setting the diaphragm to the second diaphragm value. The aperture area may be increased or decreased for diaphragm matching with the quantity of flashed light and the distance to the subject during diaphragm priority flash photography.
