摘要： Continuous photography control for a camera wherein an autofocus system is provided, and a motor is used commonly to move a taking lens for focusing and to open and close a shutter for exposure. When a mode switch is operated to set a continuous photography mode wherein plural exposures are continuously performed, the motor is driven to move the taking lens from an initial position into an in-focus position that is determined by the autofocus system and, thereafter, to open and close the shutter a selected number of times while maintaining the taking lens in the in-focus position. The taking lens is returned to the initial position after the selected number of exposures are performed. Alternatively, when another mode switch is operated to set a photography mode wherein only a single exposure is performed per one depression of the shutter button, then the taking lens is moved from the initial position to the in-focus position; the shutter is opened and closed only once; and then the taking lens is moved back to the initial position.

摘要： A self-photographing method for an autofocus camera, wherein, upon depression of a shutter release button, the subject distance data are detected a plurality of times at periodic intervals, and a predetermined exposure operation, that is, an actual shutter release operation is automatically executed using the autofocus system when the detected subject distance data have changed from each other. The distance data are repeatedly detected and compared with each other until these distance data differ from each other. If the distance data have been equal for a predetermined time interval from the shutter release button depression, then the actual shutter release operation is executed, or is called off and the self-photographing is terminated. It is preferred that the detected change of distance be a decrease of distance, indicating that the photographer has stepped into the picture, whereupon the measured distance becomes his distance in place of the background distance.
摘要翻译： 一种用于自动对焦照相机的自拍方法，其中，按下快门释放按钮时，以周期性间隔多次检测被摄体距离数据，并且自动执行预定的曝光操作，即实际快门释放操作 当检测到的被摄体距离数据彼此改变时，使用自动对焦系统执行。 重复检测距离数据并将其进行比较，直到这些距离数据彼此不同。 如果从快门释放按钮按下的距离数据已经相等预定的时间间隔，则执行实际的快门释放操作，或者被关闭，并且终止自拍。 优选地，检测到的距离变化是距离的减小，表示拍摄者已经进入图像，于是测量的距离成为他的距离代替背景距离。

摘要： A camera according to the present invention prevents distance measurement errors in remote control shots under high luminance and those in which the distance of a background between right and left objects is measured, by projecting a remote control signal including a ranging signal in a form of infrared beam from a transmitter. The ranging signal, within the remote control signal, includes multiple pulses with different pulse widths, and each pulse width is set so that the number of pulses received by the receiving circuit becomes fewer accordingly as the distance between the transmitter and a receiver provided in the camera becomes larger. When the receiver receives a ranging signal from the transmitter, a distance recognizing unit counts a pulse number of the ranging signal received by the receiver, and recognizes the distance to the transmitter, namely the object, from the relationship of received pulse numbers and distance stored in a memory unit.

摘要： A pre-winding control device of a camera which continues pre-winding from where it left off after a power failure interruption and battery replacement. When a patrone is loaded in the camera, the total number exposures is read from the patrone and the read number of written to an electrically rewritable non-volatile memory E.sup.2 PROM. Subsequently, pre-winding for winding the film from the patrone to a spool is started. For every frame of film wound to the spool, the number of unexposed frames in the patrone is counted down and written to the E.sup.2 PROM. When pre-winding is interrupted due to battery replacement, pre-winding is continued based on the number of unexposed frames stored in non-volatile E.sup.2 PROM.
