摘要:
In a camera having an automatic flash light control system, a quantity of flash light illuminating an object is restricted by a value as an upper limit or a lower limit which is calculated by a distance to the object and an aperture value of a taking lens. When there is any factor for affecting the calculation of the value such as a high reflectance of the object, a specific lens system of the taking lens and a position of the flashing unit with respect to the camera, the limit value is compensated or the restriction by the value is release. When the flash light control has completed, the flash light control mode is distinguished by indication manner corresponding to the result of the actual flash light control.
