    • A motor driven camera includes a plurality of motors for independently driving individual actuators of a camera such as film winder, shutter charger, a drive associated with a movable reflecting mirror and diaphragm driver. In addition, the camera includes a storage battery, a drive circuit for feeding the power from the battery to the plurality of motors, and a controller which controls the drive circuit. In accordance with the invention, a film winding rate or the rotational speed of a motor which performs a shutter charging operation or the speed of operation of the movable reflecting mirror or the voltage of the power supply is detected, and the plurality of motors are automatically switched between the concurrent drive and the sequential drive in accordance with the detected value. Subsequent to the switching, either drive to which the operation is switched is maintained.

    • A diaphragm apparatus is disclosed including a piezoelectric actuator of bimorph type. A drive circuit associated with the actuator applies a voltage corresponding to a diaphragm aperture which is calculated in accordance with a photometric value to the actuator to produce a displacement thereof, which is transmitted through a diaphragm operating member to open or close diaphragm blades so as to control a diaphragm aperture. The drive circuit applies a reset voltage which resets the diaphragm blades to a predetermined reset condition, to the piezoelectric actuator, and after the resetting operation, it applies a voltage corresponding to a given diaphragm aperture to the piezoelectric actuator.
    • 公开了一种包括双压电晶片型压电致动器的隔膜装置。 与致动器相关联的驱动电路将对应于根据测光值计算的光阑孔径的电压施加到致动器以产生其位移,该位移通过隔膜操作构件传送以打开或关闭光阑叶片,从而 控制光圈孔径。 驱动电路将复位电压施加到压电致动器的预定复位条件下,并且在复位操作之后,将对应于给定的光阑孔径的电压施加到压电致动器。

    • An electronic image pickup apparatus of the present invention is constructed so that an image pickup lens and a diaphragm for adjusting exposure can operate in interlocking relationship with each other. Furthermore, the apparatus has a panorama mode in which an image is obtained by connecting images taken in a plurality of continuous scenes with each other, and a rapid shooting mode in which continuous image pickup is performed. If the operating mode is set to the panorama mode or the rapid shooting mode, reset of the image pickup lens and diaphragm is performed at the first shot only and the backlash cancellation of the image pickup lens is performed starting from the second shot. Preferably, the exposure adjusting mechanism automatically places a predetermined limit on the exposure time in a normal mode and permits a longer exposure time in the panoramic mode.
    • 本发明的电子摄像装置被构造成使得用于调节曝光的图像拾取透镜和光阑可以彼此互锁的关系操作。 此外,该装置具有全景模式,其中通过将在多个连续场景中拍摄的图像相互连接而获得图像,以及执行连续图像拾取的快速拍摄模式。 如果操作模式被设置为全景模式或快速拍摄模式,则仅在第一镜头执行摄像镜头和光阑的复位,并且从第二镜头开始执行摄像镜头的间隙消除。 优选地,曝光调节机构在正常模式下自动对曝光时间设定预定限制,并且允许在全景模式下更长的曝光时间。
