    • A camera comprises a main switch, a battery, a battery checking circuit, a display device, a timer and a controller. The camera can be operative by the turn ON of the main switch and can not be operative by the turn OFF of the main switch. The battery supplies an electrical power to circuits in the camera. The battery checking circuit checks a state of the battery. The timer counts a predetermined period of time in response to the turn ON of the main switch. The controller controls the display device based on a result of the battery checking circuit to display the state of the battery during the predetermined period of time and turning off a display of the display device if the state of the battery is better for the camera than a predetermined state after a lapse of the predetermined period of time. Thereby, it is easy to see the other display of the camera in the display device.
    • 相机包括主开关,电池,电池检查电路,显示装置,定时器和控制器。 相机可以通过主开关的接通操作,并且不能通过主开关的关闭操作。 电池为相机中的电路供电。 电池检查电路检查电池的状态。 定时器响应于主开关的接通而计数预定的时间段。 控制器基于电池检查电路的结果控制显示装置,以在预定时间段期间显示电池的状态,并且如果电池的状态对于照相机而言是更好的,则关闭显示装置的显示,而不是 经过预定时间段之后的预定状态。 因此,容易看到显示装置中的相机的其他显示。
