摘要： A lens drive device for a camera drives a lens by a motor to a position preset by an operator. The lens position is stored in a memory. When the lens is to be moved to the stored position while the lens is moved by an auto-focus device to an in-focus position, the lens is instantly moved by the motor to the stored position based on the data stored in the memory.

摘要： The present invention refers to a system for digitally indicating the digital input information, and particularly for avoiding the flickering of the indication state of the indication means in case the input information varies. The system includes a control means for conveying the digital input information to the indication means periodically to update the content of the indication means at the end of a determined period. When input information varies excessively, it is detected and immediately conveyed to the indication means independently of the update at the end of the determined period. Accordingly, the system is quite efficient as an indication system for a continuously varying input information.

摘要： An exposure control device is disclosed which has an extremely high accuracy as compared with the prior art, the error range being within a one-eighth step. For such a highly accurate control of exposure time, a value of exposure time to be determined is converted to a binary code of n bits, of which the lowest one bit is weighed one-eighth step. Based on the decimal number corresponding to the upper m bits of the binary code, the frequency of the control signal is adjusted and is used in reading out the lower (n-m) bits of the same binary code, whereby the period of actuation of the shutter is determined.

摘要： In the view-finder of a camera having a TTL type light meter connected to an integrating-type analog-to-digital converter through a repeatedly operated electronic switch, there are positioned fifteen light emitting diodes upon selection of an exposure value by the converter, to illuminate a corresponding indicium on a scale of 15 exposure values, such as shutter times. Since a photo-cell exposed to scene light is also positioned in the view-finder, when the brightness of a scene to be photographed is lowered to such an extent that the influence of light from the energized diode on the photo-cell is not negligible, then the decoder for the diode arrangement is controlled to defer initiation of actuation of the one of the diodes which presents the display of an exposure value derived in the preceding cycle of light metering operation pending transition from the light integrating to the analog-to-digital converting step in the following cycle. With the scene brightness above the critical level, a corresponding diode is allowed to light up at the start of each cycle of light metering operation, so that the intensity of illumination on the exposure indicium is increased to make the reading of that indicium easier.
摘要翻译：在具有通过重复操作的电子开关连接到积分型模数转换器的TTL型光度计的摄像机的取景器中，在通过转换器选择曝光值时，设置了15个发光二极管，以15个曝光值的刻度照亮相应的标记，例如快门时间。由于暴露于场景光的光电池也位于取景器中，所以当要被拍摄的场景的亮度降低到这样的程度时，来自通电二极管的光对光电池的影响是不可忽略的然后控制用于二极管布置的解码器以推迟二极管中的一个的启动，该二极管中的一个显示在光计量操作的前一循环中导出的曝光值的显示，等待从光积分转换到模拟 - 数字转换步骤如下。在场景亮度高于临界水平的情况下，允许相应的二极管在每次测光操作循环开始时亮起，从而增加曝光指示灯上的照明强度，使得该标记的读数更加容易。
