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.

摘要： A photographing apparatus with a simple mechanism in which an AF sensor is employed as a light adjusting sensor. The apparatus includes a multi-AF sensor having a plurality of detecting areas for receiving light passing through a photographing lens, an AF controller for determining a focus area based upon signals outputted from the multi-AF sensor, and a light emitter for projecting light towards an object to be photographed. Prior to a main flash emission, the light emitter emits light preliminarily. On the basis of signals which are outputted from the detecting areas of the multi-AF sensor and which correspond to a reflected light from the object at time of emitting the preliminary flash light, a suitable area which outputs a suitable signal for photography is selected. On the basis of the signal of the suitable area thus selected, the amount of light of the main flash emission is determined.

摘要： In a flash light amount control device capable of operating according to multiple methods, the flash light control method alternates according to the detected AF mode setting, the camera panning status, or the reliability of the detected object distance. For example, if AF lock is on, control is performed by flash light adjustment, but if AF lock is not on, control is performed by flashmatic. If panning is performed after AF lock, the method of control alternates between flash light adjustment and flashmatic in response to the amount of panning movement.
