Camera capable of sensing deficiency in light quantity of flash and control method therefor |
摘要 |
A camera capable of sensing and indicating insufficient flash illumination which can indicate lack of illumination when an object is far away and in a low brightness condition. A central processing unit CPU of the camera is connected to a switch block including a power switch, a first step release switch, a second step release switch, and a switch for sensing whether an auxiliary flash is mounted. The camera also includes an automatic distance measuring circuit, a brightness measuring circuit, an auxiliary flash, and an alarm. The CPU informs a user that the auxiliary flash should be used when it is determined that a brightness value is lower than a predetermined minimum brightness value and the object is too distant to be sufficiently illuminated.
