摘要： The disclosed control system controls the diaphragm aperture of a camera in accordance with a preselected shutter time. A diaphragm scanner produces one pulse for each change of one stop in the size of aperture opening. When the required value of the diaphragm aperture, as determined in Apex form, is a number having an integer and a decimal fraction, the diaphragm aperture is adjusted in accordance with the integer, and the shutter time is adjusted to a value obtained by factoring the decimal fraction into the preset value of shutter time. Corresponding adjustment of the shutter time assures a one-eighth-stop accuracy in exposure control despite the diaphragm aperture being varied in one-stop increments.

摘要： This invention relates to cameras capable of making exposures in shutter priority, or manual and program modes. Since in the program mode the shutter time and diaphragm aperture are unequivocally determined, the computed value of shutter time is liable to exceed a limit such that effects of shaking of the operator's hand become noticeable. The present invention solves this problem by making use of the shutter dial used for selection of the shutter priority or manual mode to set the limit value. When a longer shutter time than this limit is derived, the diaphragm aperture is readjusted in accordance with this limit of shutter time and the object brightness, while the shutter is adjusted to that limit value.
摘要翻译： 本发明涉及能够进行快门优先曝光的照相机，或手动和程序模式。 由于在程序模式中明确地确定了快门时间和光阑孔径，因此计算出的快门时间值容易超过操作者的手抖动的效果。 本发明通过使用用于选择快门优先级或手动模式的快门拨盘来设置限制值来解决这个问题。 当获得比此限制更长的快门时间时，根据快门时间和对象亮度的这个限制来重新调整光阑孔径，同时将快门调整到该限制值。

摘要： The present invention concerns with a so-called program-controlled camera where only one different combination of diaphragm aperture and shutter time value is determined based on a different object brightness. Particularly in the program-controlled camera where the object brightness is measured at the full open aperture and then combined with the preset value of film speed to derive a difference between the full open aperture and the effective diaphragm value, in accordance with which the shutter time is controlled while the diaphragm is adjusted to that effective value, a device is provided for carrying out a program shift in automatic response to the full open aperture value of the interchangeable lens used in the camera.
