摘要： An automatic-focus camera has a focus lock system that stores focus adjusting information so that a photo-taking lens may be kept focused on an object during one or more exposures. The camera has a self timer, an automatic exposure system with different program modes, and has continuous as well as single-frame operating modes. The focus lock system, which has different focus lock modes, influences the manner in which various operations of the camera are performed.

摘要： An electrically operated camera having a release means for effecting a shutter release action for the light exposure of film is capable of determining whether a film is loaded or not in the basis of the film feeding condition. A film feed detection means detects the action of a film being rewound by a film rewind means, and generates a signal upon detection. When a controller receives the signal during the film rewind action, the controller prevents the release means from effecting shutter release after the completion of the rewind action. When no signal is received during the rewind action, the controller permits the release means to effect shutter release after the completion of the rewind action. The action of the film feed condition may alternatively be detected when it is being wound by a film wind means. If it is determined that the camera is loaded with a film, release lock is effected so as to prevent the exposed frame from being subjected to any further exposure by the user. If a film unloaded state of the camera is determined, it can perform the release action, thereby facilitating the checking of its various actions.
摘要翻译： 具有用于进行薄膜曝光的快门释放动作的释放装置的电动照相机能够基于胶片供给条件来确定胶片是否被加载。 胶片馈送检测装置检测由薄膜反绕装置倒带的胶片的作用，并在检测时产生信号。 当控制器在胶卷倒带动作期间接收到信号时，控制器防止释放装置在倒带动作完成之后进行快门释放。 当在倒带动作期间没有接收到信号时，控制器允许释放装置在倒带动作完成之后实现快门释放。 当胶片送风装置被卷绕时，也可以检测胶卷进给条件的动作。 如果确定相机装满了胶片，则进行释放锁定，以防止曝光的框架被用户进一步曝光。 如果确定了相机的胶片卸载状态，则可以执行释放动作，从而便于检查其各种动作。

摘要： A camera capable of operating in a red-eye prevention mode. The camera has an electronic flash device which is activated by a drive circuit in synchronization with the exposure. The electronic flash device also serve as a pre-light-emission device capable of performing pre-light-emission for the purpose of preventing red-eye effect. When it is judged from the photographing condition that red-eye effect may occur, a controller activates the electronic flash device to effect a pre-light-emission for reducing the size of pupils of eyes of a person to be photographed, before the main flashing which is executed in synchronization with the exposure.

摘要： A camera with a built-in self-timer, flash and autofocus is disclosed. The camera is switchable between normal and self-timer modes. When in the normal mode, the auto focus device measures distance at the beginning of a photographic cycle. In self-timer mode, the auto focus device measures the distance at the beginning of the photographic cycle, and after the self-timer has counted down from its set time. A decision to use the flash is based on the first distance measurement and the scene brightness in the normal mode, and on the second distance measurement and scene brightness in the self-timer mode. If the decision is yes, a checking apparatus checks whether the flash capacitor has sufficient charge, and if not charges the capacitor.

摘要： A distance-measuring apparatus comprises a first detecting device for detecting a distance to a central portion of an object field corresponding to a photographing frame and generating data corresponding to a detected distance, a second detecting device for detecting distances to a plurality of peripheral portions of the object field except for the central portion and generating data corresponding to detected distances, and an operating device for operating the first and second detecting devices. The oeprating device has a first operation step of operating the first detecting device and a second operation step of operating the second detecting device. The first step is executed to determine the detected distance to the central portion. The execution of the second step depends on the determination result and may produce an average peripheral distance output or a shortest peripheral distance output for driving a phototaking lens. Depending upon the determination result, a central distance output may instead by produced.
