    摘要: A digital display system connected to an exposure indicator in a camera to provide a digital display representative of the exposure value in shutter speed by an array of numerical indicators of the block number eight type. When the numerical value of shutter speed is equal to or larger than one second, the indicator which is directly to the right of the least significant digit is utilized to display an indicium representing a "second" unit as is usual in digital stop watch art by driving a pair of upper-positioned parallel segments in the "FIG. eight" pattern to be lit serially from the least significant digit.

    摘要: A conversion system for a camera of a type controlled through computation of digital information. The system converts a coded digital value into a digital value of another coding. The code which comprises a gray code representing an integer part of the value and a code pattern representing a decimal part of the value is converted in such a manner that: The integer part is converted into a binary code while the decimal part is converted into a code to which a weight of 1/2, 1/4 or 1/8 is applied. With such a method of conversion employed, values set at 1/3 increment or decrement steps such as ASA film sensitivity values are readily converted into binary codes to facilitate the computing operation of the camera.

    摘要: In the display system disclosed, a manually operated switching arrangement sets a display circuit, which displays data in response to a data signal from a data circuit, either into a display mode or a non-display mode. A control arrangement controls the display of the display circuit independently of the switching arrangement and produces a display signal automatically when a display operation is necessary. A warning circuit sets the display circuit into the display state independent of the switching means for displaying warning data instead of display data.

    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.

Thus only the voltage between the selecting electrodes is highter than the threshold value. An input change over device is provided so as to change over the input signal group in a time dividing way in such a manner that a plural number of dots can be displayed visually at the same time, as a result, the wiring is simplified.
