摘要： A self-scanning type photoelectric conversion element drive device, particularly, such a drive device applied to a focus detecting device of a camera, in which the effective dynamic range of the device is made very broad without a complex circuit arrangement. First and second photoelectric element arrays are scanned serially in the case that a sensed light intensity is below a predetermined value and scanned in parallel when the light intensity exceeds the predetermined value. For serial scanning, the outputs of the photoelectric elements are applied directly to an output terminal. In the case of parallel scanning, the output of one of the arrays is stored in a memory and then applied to the output terminal.

摘要： A signal indicating that the correct exposure value has been achieved and a signal indicating the completion of flash are logically summed to provide a shutter closing signal. This ensures that the shutter will be closed even when the light emitted by the flash is insufficient to achieve the proper level of exposure.

摘要： A self-timer in a camera which has a shutter priority automatic exposure adjustment (EE) mode, a manual exposure adjustment mode or an aperture priority automatic exposure adjustment (ES) mode, or all three exposure adjustment modes. In the (EE) mode, light passing through a lens aperture is received by a light receiving element while the lens aperture is being stopped down. When an aperture value (the quantity of light) suitable for the preset shutter speed and film sensitivity is obtained the supply of current of an aperture control magnet having attracted an aperture locking lever is interrupted to lock the operation of the aperture thereby to determine an aperture value. Simultaneously the locking of a top curtain is released by the lever. The camera has an interlocking timer circuit in which, in modes other than the (EE) mode, the supply of current to the aperture control magnet is interrupted in a period of time such that a period of time required for stopping down the aperture to its minimum aperture value is made slightly longer, thereby to release the top curtain. A switch for changing the time constant of the interlocking timer circuit is provided to increase the operating time of the interlocking timer circuit.

摘要： An electrically controlled camera device is disclosed which includes a counter for counting the number of pulses representative of the preferentially selected one exposure condition of a shutter speed and a diaphragm aperture level to control the preferentially selected one exposure condition, and a digital operation circuit for calculating the other exposure condition in the form of a number of digital pulses in accordance with the output pulses from the counter and with digital data signals representative of the sensed scene brightness and the film sensitivity used. During automatic exposure, the number of pulses counted by the counter is controlled by the combination of a pulse generator and a single-throw mechanical switch connected between the pulse generator and the counter, and the number of output digital pulses from the digital operation circuit is counted by another counter for controlling the other exposure condition. During manual exposure, the number of pulses representative of the other exposure condition is controlled by the combination of the pulse generator and another single-throw mechanical switch and counted by the other counter coupled to the pulse generator through an automatic/manual change-over switch and the other single-throw mechanical switch and controlling the other exposure condition. Both the single-throw mechanical switches are arranged to be operated by corresponding push buttons mounted outside the camera housing, and two sets of indicator lamps for displaying both the exposure conditions are arranged within the field of view of the camera finder.

摘要： A novel photometric circuit for a camera is disclosed wherein the operational amplifiers common to conventional photometric circuits are eliminated from that part of the circuit which solves the exposure Apex indication equation: S.sub.v + B.sub.v = A.sub.v + T.sub.v. The variable resistors which are used to convert the film sensitivity and aperature settings into electrical quantities are positioned in the feedback circuit of the transistor which is connected to the electro-optical transducer and which develops a voltage dependent upon scene brightness.
