摘要： In the display system disclosed, a manually operated switching arrangement sets a display circuit, which displays data in response to a data signal from a data circuit, either into a display mode or a non-display mode. A control arrangement controls the display of the display circuit independently of the switching arrangement and produces a display signal automatically when a display operation is necessary. A warning circuit sets the display circuit into the display state independent of the switching means for displaying warning data instead of display data.

摘要： A conversion system for a camera of a type controlled through computation of digital information. The system converts a coded digital value into a digital value of another coding. The code which comprises a gray code representing an integer part of the value and a code pattern representing a decimal part of the value is converted in such a manner that: The integer part is converted into a binary code while the decimal part is converted into a code to which a weight of 1/2, 1/4 or 1/8 is applied. With such a method of conversion employed, values set at 1/3 increment or decrement steps such as ASA film sensitivity values are readily converted into binary codes to facilitate the computing operation of the camera.

摘要： In the disclosed camera, an exposure value determining arrangement produces an electrical signal in response to a light measuring facility and a film sensitivity setting device. An exposure factor unit determines a combination of shutter speed and aperture value for a proper exposure in response to the exposure value determining arrangement. A control connected to the exposure factor unit varies the combination of exposure factors in the exposure factor unit in response to the set position of a program constant setting arrangement which is set for a particular program constant.

摘要： A release locking device for use in photographic cameras of the type in which an exposure meter and electromagnetic actuating and releasing means for automatic exposure control are rendered operative in separate manner by their respective control or release switches as may be operatively associated with a display button and a shutter release button respectively. This device comprises a master switch connected between an electrical power source and a common input lead of these release switches to be closed and opened in response to an actuation and a release, respectively, of a manually operable member, thereby all of the release switches are rendered effective and ineffective at a time. In a preferred embodiment, this device is operatively associated with a shutter cocking mechanism to be actuable in automatic response to a protracting movement of the shutter cocking lever into an effective range of shutter cocking operation.

摘要： In a camera having an exposure factor setting dial positioned adjacent a film winding lever, there is provided a safety device including a movable cover arranged to protrude upwardly from the inside of the camera housing over a top panel thereof to prevent the operator from inadvertently manually altering the setting of the dial, whereby improper actuation of the dial is prevented and the camera is made substantially fool-proof. When the cover is retracted into the camera housing by engagement of a knurled key portion thereof, the operator may actuate the dial to revise the exposure setting.

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。
