摘要： In the disclosed system shifting light-measuring modes are shifted by restricting the view angle of a light sensitive element or by producing differences between a first light measuring circuit and a second light measuring circuit, each having a different light measuring range. A correction circuit determines aperture corrections for mode changes. When the exposure is controlled, the output of the light measurement is corrected by the output of the correction circuit.

摘要： An exposure controlling device comprising a means of discriminating to what zone of exposure zones sectioned in advance an exposure value determined by considering the brightness information of an object to be photographed obtained by a TTL light measurement under the maximum diaphragm aperture and the film sensitivity of the film to be used belongs, a means of determining a diaphragm value simultaneously with and in response to the discrimination of the exposure zone and a means of comparing the determined diaphragm value with the F-number of a photographing lens to be used and controlling a proper exposure time corresponding to said diaphragm value so that a diaphragm aperture and shutter speed for obtaining a proper exposure can be automatically set without making any special switching operation even in the case of using any photographing lens different in the F-number. The means of determining the diaphragm value includes a member which can be intermittently driven by a pulse signal. By the initial motion of this member, a mirror mechanism or automatic focus adjusting device can be released.

摘要： An improved control circuit for an electromagnetic actuator of the type having an armature mounted for movement in a magnetic field, and means connected to the armature for urging the armature toward a rest position. The circuit applies an electrical pulse of a first polarity, magnitude and duration to the armature to quickly move the armature to a programmed position determined by the magnitude and duration of said pulse, the programmed position lying within a range of positions between said rest position, and an extreme position achievable by the armature. The control circuit then applies a pulse of opposite polarity and of magnitude and duration effective to stop the armature at the programmed position. The control circuit applies a periodic train of pulses of said first polarity, of fixed magnitude and of duration, effective to hold the actuator in the programmed position, the period of said train of pulses being above the natural cutoff frequency of the actuator. To quickly return the armature to the rest position, the control circuit applies a pulse of opposite polarity and of duration and magnitude effective to the armature to move the armature in cooperation with the urging means, to the rest position. The circuit then applies a braking pulse of said first polarity and of duration and magnitude effective to stop the armature at the rest position.In a preferred embodiment, the actuator controls a shutter/aperture in a camera, the duty cycle (i.e. pulse duration) of the train of pulses determines the aperture size, and the number of pulses in the pulse train determines the shutter time. The control circuit also includes means for boosting the voltage of the moving and braking pulses to achieve extremely short shutter times.

摘要： The present invention relates to the exposure compensation information forming apparatus for a camera, particularly for forming the aperture and the totally opened aperture value information. Until now in order to compensate the totally opened aperture value contained in the output of the light measuring circuit and the aperture value the information setting means for the totally opened aperture value and that for the aperture value are provided, whereby both setting means are mechanically engaged with each other so as to form the totally opened aperture and the aperture information. Thus, the engaging mechanism of both of the above means is complicated, which is inconvenient. The present invention provides an exposure compensation information forming apparatus by means of which the aperture information can be composed from the totally opened aperture with a very simple circuit composition so as to overcome the above disadvantage.
