摘要： A plural number of switches which are selectively opened and closed comprise a first switch corresponding with the weight "2/3" in APEX value and a second switch corresponding with the weight "1/3" in APEX value while a n bit register comprises a first bit with the weight "1/2" in APEX value, a second bit with the weight "1/4" in APEX value and a third bit with the weight "1/8" in APEX value. The closing signal of the first switch is put in the first bit, the closing signal of the second switch in the second bit and the closing signal of the third switch in the third bit so as to carry out the approximate conversion of the data.

摘要： An apparatus for setting an exposure control factor into a camera in the form of a digital signal without using a code plate or a plurality of switches. A pulse train is fed to a binary counter through an AND circuit which, upon selective receipt of gating-on and gating-off signals, operates to initiate and terminate flow of pulses therethrough respectively. When the counter has counted the selected number of pulses, the photographer who is viewing a digital display unit cooperative with the counter to detect this pulse number may actuate a button to produce the gating-off signal, thereby a corresponding desired value of the exposure control factor is set into the camera as a function of the number of pulses counted.

摘要： The present invention relates to a camera with a displacement means for controlling the exposure amount as the function of the mechanical displacement position. The displacement means are so designed that a brush is slid over a comb-shaped conductive pattern mechanically linked with the displacement means so as to convert the displacement position of the displacement means into a pulse number. Further, when the pulse number reaches a certain determined value, the displacement means is stopped in such a manner that the pulse number corresponds with the exposure amount and characterized in that, by determining the position at which each conductor of the comb-shaped conductive pattern is provided, relative to the position at which the displacement means stops in accordance with the displacement speed of the displacement means, the displacement amount of the displacement means due to the time delay since the pulse number reaches a certain determined amount till the displacement means actually stops is compensated so that the pulse number always corresponds with the displacement position in a precise way.

摘要： A number of separate comparators compare respective analog inputs to a single reference waveform and turn off respective gates when the analog voltages achieve predetermined relationships to reference wave form. The gates pass pulses from a common source from the beginning of the reference wave form until the respective gates are shut off. In one version the analog signals represent photographic data such as diaphragm aperture and shutter speed in a camera, and are digitized for display within the camera.

摘要： A device for preventing erroneous handling of a camera capable of dual type automatic exposure control including shutter time preference and diaphragm preference, wherein the device senses whether the camera is set at a diaphragm preference position or at a diaphragm automatic adjusting position with regard to the diaphragm setting means, and whether the shutter time preference position or the shutter time automatic adjusting position is selected for the shutter time setting means. The camera is rendered inoperative when both the diaphragm setting means and the shutter time setting means are set in their respective preference positions.

摘要： In the disclosed photographic exposure control system, an exposure mechanism generates at least one controllable exposure parameter for regulating the exposure of a photosensitive material. A coding circuit is set to produce digital signals corresponding to at least one photographic value. A control device between the coding circuit and the exposure mechanism calculates the exposure parameter and controls the coding circuit.

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.
