摘要： A photographic information display apparatus for a camera provided with at least three display chips. The second chip has a number of segments less than the first chip while the segments of the third display chip are connected to a driving signal transfer line of an encoder which is not connected to the segments of the second chip. This arrangement dispenses with another driving signal transfer line for the third display chip.

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.

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： In the disclosed camera, an exposure value determining arrangement produces an electrical signal in response to a light measuring facility and a film sensitivity setting device. An exposure factor unit determines a combination of shutter speed and aperture value for a proper exposure in response to the exposure value determining arrangement. A control connected to the exposure factor unit varies the combination of exposure factors in the exposure factor unit in response to the set position of a program constant setting arrangement which is set for a particular program constant.

摘要： The present invention concerns with a so-called program-controlled camera where only one different combination of diaphragm aperture and shutter time value is determined based on a different object brightness. Particularly in the program-controlled camera where the object brightness is measured at the full open aperture and then combined with the preset value of film speed to derive a difference between the full open aperture and the effective diaphragm value, in accordance with which the shutter time is controlled while the diaphragm is adjusted to that effective value, a device is provided for carrying out a program shift in automatic response to the full open aperture value of the interchangeable lens used in the camera.

摘要： This invention relates to cameras capable of making exposures in shutter priority, or manual and program modes. Since in the program mode the shutter time and diaphragm aperture are unequivocally determined, the computed value of shutter time is liable to exceed a limit such that effects of shaking of the operator's hand become noticeable. The present invention solves this problem by making use of the shutter dial used for selection of the shutter priority or manual mode to set the limit value. When a longer shutter time than this limit is derived, the diaphragm aperture is readjusted in accordance with this limit of shutter time and the object brightness, while the shutter is adjusted to that limit value.
摘要翻译： 本发明涉及能够进行快门优先曝光的照相机，或手动和程序模式。 由于在程序模式中明确地确定了快门时间和光阑孔径，因此计算出的快门时间值容易超过操作者的手抖动的效果。 本发明通过使用用于选择快门优先级或手动模式的快门拨盘来设置限制值来解决这个问题。 当获得比此限制更长的快门时间时，根据快门时间和对象亮度的这个限制来重新调整光阑孔径，同时将快门调整到该限制值。

摘要： In the disclosed viewfinder, a focusing plate receives light from an objective via a reflex mirror, and after focusing, passes light to an eyepiece via a penta prism. A by-pass optical system receives light from outside the view field of the viewfinder and directs the light through an information carrier outside the optical path of the photographic light and into the penta prism so that the information can be displayed close to the view field of the viewfinder.
