    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.
