    摘要： 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.

    摘要翻译： 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。

    摘要： 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.

    摘要： A camera body has mounted on it a lens mount which is pivotable relative to the camera between an operative and an inoperative position. A mechanism in the camera is activated and transports film from the camera film chamber through the camera during movement of the lens mount from one to the other (or from the other to the one) of the aforementioned positions.

    摘要： A sheet of exposed and developed instant-camera film is discharged from an instant camera and then inserted by the user into a film-holding structure on the back of the camera which very accurately positions the film sheet, such that upon removal and reinsertion of the film sheet into the holding structure the film sheet will always assume a predetermined position. The camera is provided with a multihead magnetic head unit mounted for reciprocating motion along a magnetic strip or coating provided at a marginal portion of the inserted film sheet. During first-direction travel of the head unit, one head records, and during second-direction travel of the head unit a different and differently located head records onto a further segment of the magnetic strip. After recording, the recorded information, e.g., spoken words identifying the subject just photographed, can be reproduced, and if desired erased.

    摘要： A motorized still camera has a housing which can receive film cassettes in a film chamber at the rear side of the housing. A motor-drive of the camera includes a motor which is located forwardly of the cassette take-up section, in direction towards the front side of the camera. A motor-controlling mechanism and a film transporting mechanism of the motor drive are so dimensioned as to require relatively little space in direction vertically of the camera and in direction between the front and rear side, but instead to have their major dimensions extending lengthwise of the housing so as to make optimum use of the space available in the housing.

    摘要： 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.
