    摘要: The apparatus of the present invention is provided with flashing device for effecting preliminary flashing and main flashing, a split photometry unit for metering reflected light from the area of the object field divided into a plurality of areas and outputting a photometric output for each of these areas, preliminary flashing control unit, a calculation unit and a main flashing control unit. The preliminary flashing control unit causes the flashing device to effect preliminary flashing prior to main flashing, and when in that case, at least one of the photometric outputs from the split photometry unit reaches a predetermined value, causes the flashing device to repeat the preliminary flashing while decreasing the quantity of emitted light thereof, and when the photometric outputs become null before the predetermined value is reached, causes the flashing device to stop the preliminary flashing. The calculation unit determines the divided areas which are not used for the flash limiting during the main flashing by the use of the photometric outputs and the quantity of emitted light during preliminary flashing at the last stage. The main flashing control unit controls the main flashing of the flashing device on the basis of the output of the calculation unit.

    摘要: A camera body to which a photographing lens storing data associated with a full-aperture value and data associated with a position of an exit pupil can be attached, includes an optical member for scattering radiation from the photographing lens, light-receiving element, and a photometric optical system for guiding the radiation from the photographing lens through the optical member toward the light-receiving element. The optical member is arranged on a side opposite to an object with respect to the photographing lens. The light-receiving element generates an output according to the radiation incident from the photometric optical system. The camera body further includes a correction circuit for reading out the data associated with the full-aperture value and the position of the exit pupil, calculating a correction amount based on the readout data, and correcting the output from the light-receiving element based on the calculated correction amount, and an exposure control circuit for performing exposure control based on the corrected output.

    摘要: A miniaturized ultrasonic motor comprises a stator having an elastic body on which a travelling oscillatory wave is generated and which is supported on a fixing unit in a manner that prevents rotation of the elastic body but permits axial movement of the elastic body. The travelling oscillatory wave rotates a rotor that contacts protruding portions of the elastic body, and the rotor rotates a driven body therewith. The driven body engages the rotor in a manner that constrains the driven body to rotate with the rotor but that permits relative axial movement of the driven body and the rotor body.

    摘要: An automatic exposure device in a camera divides an object field into a plurality of areas and photometers them by the use of a divisional photometry element, and calculates optimum exposure from the result of the photometry. The divisional photometry element includes a photometric converting portion for photoelectrically converting incident light in each of the areas and putting out an output, and a reading portion for reading out the plurality of outputs of the photoelectric converting portion. When the number of successive outputs of a row of the areas in the readout direction which exceed a predetermined value is greater than a predetermined number, the output of that row is completely omitted in the calculation of the optimum exposure.
