    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： An exposure control apparatus for a photographic camera wherein various exposure control parameters after being digitized are applied to a computer. The computer then derives an exposure value based on digital computation. The apparatus is provided with combined means for converting the preselected exposure control parameters to corresponding mechanical displacements and for converting the displacements directly to corresponding numbers of pulses, whereby the computer is made responsive to the numbers of pulses.

    摘要： In the camera disclosed, depending upon whether the shutter preference or aperture preference mode is selected, a computer establishes a computed value on the basis of a preset value and other ambient conditions. A number of separate comparators compare the respective values to a single reference wave form and turn off respective gates when the analog voltages achieve predetermined relationships to the reference wave form. The gates passed pulses from a common source from the beginning of the reference wave form until the respective gates are shut off. The values are thus digitized and displayed within the camera.

    摘要翻译： 在所公开的照相机中，根据是否选择快门偏好或光圈偏好模式，计算机基于预设值和其他环境条件建立计算值。 多个独立的比较器将各个值与单个参考波形进行比较，并且当模拟电压达到与参考波形的预定关系时，关闭各个门。 栅极从参考波形开始通过来自公共源的脉冲，直到各个门被切断。 因此，这些值被数字化并显示在相机内。
