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.

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： An exposure control apparatus operating with selection of the diaphragm preselection and shutter preselection automatic exposure control modes is provided with first and second signal shapers arranged to cooperate with a lens aperture mechanism through a common intermediate member. Upon setting of a desired diaphragm value in the lens aperture mechanism, the intermediate member is driven along with the first signal shaper in exactly corresponding relation. In the shutter preselection automatic diaphragm control mode, while the first signal shaper is cut off from connection with an exposure value computer, the second signal shaper is driven for scanning operation to produce ever-varying outputs which are compared with the output of the computer upon coincidence to stop movement of the lens aperture mechanism, thereby the scanning result is translated to the proper diaphragm presetting, as the intermediate member is arranged to delay the start of movement of the lens aperture mechanism from the start of the scanning operation by a time interval determined by taking into account the signal response characteristics of the automatic diaphragm adjusting mechanism.

摘要： An automatic exposure control apparatus for controlling the diaphragm of the camera in accordance with the preselected shutter time and the exposure value, in which a digital-to-analog converter having a counter responsive to the number of pulses supplied from a clock pulse generator through a gate produces a time variable output capable of attaining a certain level dependent upon the preselected shutter time and a light value as photoelectrically sensed, that is, an exposure value and, which is detected by a first comparator. The output of the first comparator is applied to the gate, so that the converter is set to memorize the exposure value therein. As the diaphragm presetting ring is moved from the maximum to minimum aperture position with production of a time variable output from a signal generator associated therewith, a second comparator responsive to the attainment of the time variable output of the signal generator to a level dependent upon the final output of the set converter produces an output which is applied to arresting means for the diaphragm presetting ring. This results in automatic adjustment of the position of the presetting ring. At the time the presetting ring begins to move, the diaphragm driving means is actuated causing the diaphragm means to be brought into engagement with the ring. Thus, an effective exposure aperture is established in the diaphragm means.

摘要： A photographic camera having a manually and automatically adjustable diaphragm is provided with an electromagnetically operated diaphragm scanning mechanism in combination with a manually operable depth of field pre-viewing device to enable a visual determination of the utilizable zone of sharpness in a reflex viewfinder of the camera regardless of the fact that the camera remains in the run down position. For this purpose, the diaphragm scanning mechanism includes a scanning member and a driving member arranged to establish driving connection therebetwen during the automatic adjustment of the diaphragm. Release means is provided and is responsive to the termination of closing operation of the camera shutter for effecting release of the driving connection, whereby the photographer before cocking the camera is enabled to manipulate the diaphragm followed by the pre-viewing device to read off the range of sharpness in dependence on the manual setting of the diaphragm for use in making a subsequent exposure.

摘要： In a single lens reflex camera, a lever responsive to operation of a shutter button initiates timing of an electronic shutter control a predetermined time interval before the shutter is actually opened. The predetermined time interval corresponds to the time elapse between the moment the shutter control changes the current which operates the magnet that holds the shutter open and the moment the magnet actually causes the shutter to close. After this predetermined time interval the shutter is opened, such as by running of the opening screen. After the measured shutter interval has ended, a current in the shutter control changes and operates on a magnet which has been holding the shutter open and causes the magnet to close the shutter, such as by releasing a closing screen.
