  • Exposure Control For Cameras (AREA)

Abstract

PURPOSE: To prevent the occurrence of an exposure error by building a flash device and an exposure meter in the camera, and providing a means which may meet with the characteristic of the exposure meter adjusted to the amount of emitted light of the flash device and the natural light.
CONSTITUTION: Control voltage E3 rises up with the increase of resistance value of variable resistor VR1 while the voltage E3 lowers with the decrease of resistance value. Therefore the voltae E3 for controlling the exposure to be applied to the exposure meter is optionally set by adjusting variable resistors VR1, VR2, hence the voltage E3 can be set to a value such that the stroboscopic device built-in the camera and the exposure meter are comined together, the amount of emitted light is measured, and the proper value of diaphragm in accordance with the amount of emitted light may be insturcted. Accordingly, the camera with no exposure error at the time of either flash photography or natural light photography can be obtained
