摘要： The disclosed camera is provided with an automatic focus adjusting device for automatically adjusting the focus of an objective lens. A timer circuit, adapted to be actuated in synchronism with the automatic focusing device initiating focus adjustment of the objective lens, sets a predetermined time and inhibits the actuation of a shutter release device for the predetermined time. In a preferred embodiment, the shutter release actuation is controlled in accordance with the logic condition of a focus adjustment completion signal obtained from the automatic focus adjusting device and a time count completion signal produced when the predetermined time has elapsed. In another embodiment of the present invention, a battery voltage detecting circuit prevents shutter release when the voltage of the battery energizing the camera is below a predetermined level.

摘要： The active automatic focusing apparatus disclosed scans the object to be photographed with light from a light projector and includes a sensor sensing reflected light, a peak detector for detecting the peak value of the signal sensed by the sensor, a control producing a stop signal suitable for stopping focusing movement of the objective lens in accordance with the output of the peak detector, and a stop device for stopping the movement of the objective lens on the basis of the output of the control. A comparator compares the level of the detected signal with that of a preset noise signal so as to produce a first control signal when the level of the detected signal is higher than that of the noise signal. A given distance detector produces a second control signal when the objective lens is moved to a predetermined position corresponding to a distance at which a peak of the detected signal can be detected by the peak detector. An arrangement applies a second stop signal to the stop device to stop the movement of the objective lens when the first and the second stop signals are produced.

摘要： In the disclosed cameras, movable shutter members which cover a main aperture define a sub-aperture which is arranged first to close from a pre-opened state and then to open so as to control the exposure on the basis of brightness information. A first detector produces a first signal when the sub-aperture is closed, a second detector produces a second signal after a time determined by the brightness information, and a shutter detector is controlled by the first and second detectors to inform an operator that the shutter members have operated normally.

摘要： An exposure control device for a camera wherein a current produced from a light sensitive element in proportion to the quantity of light incident on the element is logarithmically suppressed. A suppressed voltage obtained from this current to which voltage is added a voltage which is substantially proportional to absolute temperature and is produced according to encoded film sensitivity information expressed in the APEX system. The voltage resulting from the addition is converted into a current and expanded. The degree of an exposure is controlled on the basis of the expanded current.
