    • An imaging apparatus of an electronic camera according to the present invention has a lens barrier arranged on an object side of a photographing lens; an imaging device capable of changing electric charge storage time; a lens barrier state-detecting means for outputting a signal indicating an opening state of the lens barrier after detecting the opening state of the lens barrier; a release switch for starting a photographing operation; an imaging device control means for starting electric charge storage of the device when the signal of the opening state of the lens barrier is outputted from the detecting means and for outputting a charge termination signal when the charge is terminated; and a lens barrier opening and closing driving means for driving the lens barrier to open on the basis of a turning-on signal of the release switch and for driving the lens barrier to close on the basis of the charge termination signal outputted from the control means. In this apparatus, by driving the driving means, the lens barrier is opened only during a photographing period, while the lens barrier is closed during a non-photographing period to prevent the device from being exposed to strong outside light.
    • 根据本发明的电子照相机的成像装置具有布置在拍摄镜头的物体侧的透镜屏障; 能够改变电荷存储时间的成像装置; 透镜屏障状态检测装置,用于在检测到透镜屏障的打开状态之后输出指示透镜屏障的打开状态的信号; 用于开始拍摄操作的释放开关; 当从检测装置输出透镜屏障的打开状态的信号并且当电荷终止时输出充电终止信号的成像装置控制装置,用于启动装置的电荷存储; 以及透镜屏障打开和关闭驱动装置,用于基于释放开关的导通信号驱动透镜屏障打开,并且基于从控制装置输出的充电终止信号来驱动透镜屏障关闭 。 在该装置中,通过驱动驱动装置,透镜屏障仅在拍摄期间打开,而在非拍摄期间透镜屏障被关闭,以防止装置暴露于强烈的外部光线。

    • A camera having a covering member which covers the upper side of the camera and having a projecting portion shaped as a pentagonal reflecting member; a first manually operable portion located at the covering member on one side of the projecting portion for designating one of a plurality of kinds of photographic data; a second manually operable portion located at the covering member on the other side of the projecting portion and adapted for commonly altering any of the plurality of kinds of photographing data to actually alter the designated one thereof in combination with the actual designation by the first manually operable portion; a light measuring device for measuring the luminance of the object to be photographed; a calculator for carrying out an exposure calculation based on the result of the light measuring; a display portion for displaying at least either one of shutter speed and aperture value obtained by the exposure calculation; and a display controller for controlling the display such that, when the first manually operable portion is operated, the display of at least either one of shutter speed and aperture value is turned off, and instead a designated photographing data is displayed.
    • 一种照相机,具有覆盖照相机的上侧的覆盖部件,并具有形状为五边形反射部件的突出部分; 第一手动操作部分,位于所述突出部分的一侧上的所述覆盖部件上,用于指定多种摄影数据中的一种; 第二手动操作部分,位于突出部分的另一侧上的覆盖部件上,并适用于共同改变多种拍摄数据中的任何一种,以便通过第一可手动操作的实际指定实际改变其指定的一个 一部分; 用于测量被拍摄物体的亮度的光测量装置; 基于光测量结果执行曝光计算的计算器; 用于显示通过曝光计算获得的快门速度和光圈值中的至少一个的显示部分; 以及显示控制器,用于控制显示器,使得当第一可手动部分被操作时,快门速度和光圈值中的至少一个的显示被关闭,而是显示指定的拍摄数据。
