摘要： An automatic exposure control method and device has photometry means for detecting the brightness of a subject and providing an output signal in response thereto, a shutter, driving means for driving the shutter toward a full aperture, closing means for closing the shutter in accordance with the output signal from the photometry means, and adjusting means for adjusting the photometry means in a stepwise manner to provide the output signal variably in accordance with the light detected and the opening position of the shutter. In one embodiment, the driving means for opening the shutter engages a series of contacts for correspondingly short-circuiting photoelectric elements providing the electrical signal output, thereby varying in a stepwise manner the charging of a capacitor in a comparator circuit for disengaging a solenoid controlling the shutter closing means.

摘要： Automatic focus adjusting device comprising a range finding means which generates a signal corresponding to a distance to an object to be photographed; means for setting a photographing lens to a position corresponding to the output signal from the range finding means; a primary judging means which judges whether or not a diaphragm setting is within the range in which fixed focus photographing is possible or not; and a secondary judging means which judges whether an output signal from the range finding means is at a level capable of operating an automatic focusing means, wherein the secondary judging means judges only when the primary judging means judges that a diaphragm setting is not within the range in which fixed focus photography is possible and the automatic focusing means is operated only when the secondary judging means judges the output signal is at a level capable of operating the automatic focusing means.
摘要翻译：自动对焦调整装置，其包括：距离寻找装置，其生成对应于要拍摄对象的距离的信号; 用于将拍摄镜头设置到与来自所述测距装置的输出信号相对应的位置的装置; 判断光阑设置是否在可能进行固定焦点拍摄的范围内的主判定装置; 以及二次判断装置，其判断来自测距装置的输出信号是否处于能够操作自动聚焦装置的水平，其中，次要判定装置仅在主判定装置判断为不在该范围内的光阑设定其中可以进行固定焦点拍摄，并且只有当二次判断装置判断输出信号处于能够操作自动聚焦装置的水平时，自动聚焦装置才被操作。
