    • When a trigger lever is depressed, both a focus adjuster ring and a control disk commence to rotate in unison, driven by a spring mechanism. Position-sensing switches receive signals indicating which subject-distance setting the focus adjuster ring should be arrested at, and furthermore are opened and closed by the control disk during movement of the latter. When the focus adjuster ring reaches the required subject distance setting, it is arrested and kept arrested, thereby completing an automatic focussing operation, but the control disk continues to turn on to its end position, at which it causes the shutter mechanism of the camera to open and furthermore the exposure-timing circuit of the camera to initiation a scene-light-dependent exposure-timing operation.

    • A first photodetector arrangement comprises three adjoining photodetectors, and a second comprises six. First and second optics, and the two photodetector arrangements, are located immovable on the camera, and the optics project onto the first arrangement an image of a subject which is to form the basis of a subject-distance measurement, without shift between image and photodetectors of the first arrangement so long as the subject-distance is within one of the ranges the system is to furnish; whereas the image projected onto the second photodetector arrangement shifts relative thereto in dependence upon the distance to the subject. The six photodetectors of the second arrangement are subdivided, for signal-processing purposes, into four successive groups, respectively comprised of the first, second and third photodetector, the second, third and fourth, the third, fourth and fifth, etc. A plurality of comparisons are performed by signal-evaluating circuitry, on the basis of absolute-value versions of the differences between the output signals of individual photodetectors in the first arrangement and in successive photodetector-groups within the second arrangement, to automatically ascertain, sequentially or non-sequentially, which photodetector-group in the second photodetector arrangement is in receipt of an image best corresponding to that cast onto the first photodetector arrangement, thereby determining the subject-distance setting best corresponding to the true subject-distance value.

    • A focussing system emits an infrared light beam towards the subject, the reflected beam passing through an infrared filter and being projected by a spot optics as a small spot onto a pair of photosensitive elements. The spot optics shifts in a plane normal to the camera's optical axis in dependence upon rotation of the camera's focussing ring, to vary the distribution of the reflected beam onto the two elements, the distribution being equal between them when the state of focus is correct. A circuit derives, from the output signals of the two photosensitive elements, a state-of-focus signal used to automatically focus or else to indicate to the user the direction in which he should manually adjust focus. When focussing is finished, the photosensitive elements are disconnected from the focussing circuitry and connected to the camera's exposure-control circuitry, to thereby serve a dual function. The infrared filter moves out of the light path of the photosensitive elements. The spot optics is moved out of the light path of the photosensitive elements, so that for exposure control a larger light field can be established, or else an auxiliary optics moves into the light path to enlarge the light field in that manner.
    • 聚焦系统朝向被摄体发射红外光束,反射光束通过红外滤光器并被作为小光点的光点投影到一对感光元件上。 光点光学根据照相机聚焦环的旋转垂直于相机光轴的平面移动,以便将反射光束分布在两个元件上,当焦点状态正确时,它们之间的分布相等。 电路从两个感光元件的输出信号中得出用于自动对焦的聚焦信号,或者向用户指示他应该手动调整焦点的方向。 当聚焦完成时,感光元件与聚焦电路断开并连接到相机的曝光控制电路,从而起到双重作用。 红外线滤光片移出光敏元件的光路。 点光学元件被移出光敏元件的光路,使得为了曝光控制可以建立更大的光场,或者辅助光学元件移动到光路中以便以这种方式放大光场。

    • A photographic still or motion-picture camera has a viewfinder and a manually moved focus adjuster, such as a focussing ring. When the user peers into the viewfinder, there is a visible indication of the direction in which the focus adjuster should be manually moved to reduce the state-of-focus error, for example two curved illuminated errors, one pointing clockwise and the other counterclockwise, only one of which lights up to indicate the direction in which the focussing ring should be manually turned. When the state-of-focus error has been reduced to zero or a minimum, this is likewise indicated, for example because neither curved arrow is illuminated. To control the activation of the indicating elements, use can be made of components of a conventional completely automatic focussing system, but minus the adjusting motor of such system and minus superfluous motor-energization control circuitry. In this way, the user is provided a simple and unequivocal guide when manually focussing, without the cost, complexity, bulkiness and power consumption of a complete automatic focussing system including an adjusting motor and motor-energization control circuitry.
    • 照相静止或动态相机具有取景器和手动移动的焦点调节器,例如聚焦环。 当用户对准取景器时,存在可以手动移动聚焦调节器的方向的可见指示,以减少聚焦误差,例如两个弯曲的发光错误,一个指向顺时针方向,另一个指向逆时针方向, 只有其中一个亮起来指示聚焦环手动转动的方向。 当聚焦误差已经降低到零或最小时,这同样被指示,例如因为没有弯曲的箭头被照亮。 为了控制指示元件的激活,可以使用常规的全自动聚焦系统的部件,但是减去这种系统的调节电机和减去多余的电动机通电控制电路。 以这种方式,在手动聚焦的情况下,向用户提供简单而明确的指导,而无需包括调节电机和电动机通电控制电路的完整自动聚焦系统的成本,复杂性,蓬松性和功耗。

    • A camera includes a viewfinder, an objective and a manually operated focus adjuster. An optical system located in the path of incoming image light splits the incoming image light beam into two component beams projected into respective first and second focal planes. First and second planar arrays of photosensitive elements are located in respective first and second photodetector planes. When the objective is correctly focussed and then defocussed in a first direction, the sharpness of the image on the first array increases and that on the other decreases; if the objective is defocussed in the opposite direction, the opposite occurs. A comparator has two outputs, connected to the elements of the first and second arrays via respective first and second circuit branches. Each circuit branch includes at least one subtractor producing an absolute-value output signal independent of the polarity of the difference between the input signals applied thereto. The subtractor inputs are connected to the outputs of respective elements of the respective one of the two arrays. The comparator output signal controls an indication, visible in the camera viewfinder, informing the user of the direction in which he should manually move the focus adjuster to improve the state of focus.
    • 相机包括取景器,物镜和手动调焦​​器。 位于输入图像光路径中的光学系统将入射的图像光束分解成投影到相应的第一和第二焦平面中的两个分量光束。 感光元件的第一和第二平面阵列位于相应的第一和第二光电检测器平面中。 当目标被正确地聚焦,然后在第一方向上聚焦时,第一阵列上的图像的清晰度增加,另一方降低; 如果目标在相反的方向散焦,则发生相反的情况。 比较器具有两个输出,经由相应的第一和第二电路分支连接到第一和第二阵列的元件。 每个电路分支包括至少一个减法器,产生与施加到其上的输入信号之间的差异的极性无关的绝对值输出信号。 减法器输入连接到两个阵列中的相应一个的相应元件的输出。 比较器输出信号控制相机取景器中可见的指示,通知用户手动移动对焦调节器的方向以改善对焦状态。

    • A photographic camera has an exposure objective and a focus adjuster device for changing the subject-distance setting of the exposure objective, as well as a transducer generating actual-setting signals dependent upon the setting of the focus adjuster device. An evaluating circuit, operative for ascertaining camera-to-subject distance on one basis or another, produces digital required-setting signals, expressed using a first encoding scheme, whereas the actual-setting signals generated by the aforementioned transducer are expressed using a different, second encoding scheme. The actual-setting signals are applied to the first input of a comparator stage, whose second input receives a transformed version of the required-setting signals, transformed from the first to the second encoding scheme, i.e., so that the comparator can compare, in a direct and simple way, the actual-setting signals and required-setting signals against each other with both signals expressed in accordance with one and the same encoding scheme. The output signals produced by the comparator control indicator which informs the user of the direction in which the manual focus adjuster of the camera should be moved to improve the camera's state of focus, and/or control the energization of an electric motor or other electromagnetic positioning device operative for controlling the setting of the focus adjusting device.

    • A collapsible camera has a lens mount which is pivoted on the camera body and can move between an open and a shut position. An arcuate drive segment is composed of at least two segment parts, both of which pivot on the same pivot axis as the lens mount. These parts can move relative to one another and to the body and lens mount when the latter is opened and closed. The periphery of each part has serrations which engage with the teeth of a pinion that constitutes the input member of a film transporting mechanism so that the pinion is rotated in response to the pivoting movement of the lens mount.
