摘要： The disclosed distance measuring device is arranged to project light on an object. Reflected light from the object is received by a photo-electric converter to shift the position of a photo-taking lens to an in-focus position on the basis of a signal produced from the photo-electric converter. The projected light and/or the reflected light is divided into a multiplicity of light fluxes for the purpose of broadening and simplifying the distance measuring range and accuracy.

摘要： In the disclosed distance measuring device a light source projects light on an object to be photographed. A photo-electric converter for receiving light reflected from the object includes at least one photo-electric converting portion whose electric charge varies according to the quantity of light incident thereon. A control includes a first electric charge store which stores an electric charge produced at the photo-electric converting portion while the light is projected from the light source, a second electric charge store which stores an electric charge produced at the photo-electric converting portion while light is not projected from the light source, and a detector which detects at least one of the amounts of electric charge stored at the first and second electric charge stores. The control varies the quantity of light projected by the light source on the basis of the result detected by the detector.

摘要： In the disclosed photo-electric conversion device, a light source repetitiously emits light and a photo-electric converter receives reflected light originally generated by the source and ambient light. A first store stores the output of the photo-electric converter when the light source emits light and a second store stores data from the photo-electric converter when the source does not emit light. A gate transfers the output from the converter to the first and second stores. A pulse generator controls the gate for transferring the converter output to the first store and the second store during every light emitting cycle of the light source.

摘要： A photoelectric transducer element responsive to ambient light and a combination of ambient and projected light from light emitting apparatus operates with a predetermined cycle by signals from an oscillator. This produces respective output signals which are then stored on first and second storing apparatus. Signals from the storing apparatus provide information necessary for photographing, since the storing operation is synchronized with the oscillating operation.

摘要： In the disclosed distance measuring arrangement, a light projector turns on and off to illuminate an object over the ambient light during projection periods when light is projected and during space periods when light is not projected. The reflected light is detected as a function of distance by integrating projection signals representing light reflected during projection periods, integrating space signals representing light during reflected space periods, subtracting the integration space signals from the projection signals, and extracting measurements based on the subtractions. Compensation for change in ambient light between periods is obtained by changing the timing of the integrations and extractions from concidence with the projections and space periods.

摘要： The disclosed device responds to pulsed light from a light source to produce electrical signals. A photo-electric transducer element uses a number of signal storage sites on which successive signals from the photo-electric transducer element are accumulated. A signal flow circuit transfers the stored signals from one of the signal storage sites to another in synchronism with the energization and de-energization of the light source. Simultaneously, those signals produced when the light source is energized are accumulated on a common storage site. The other signals produced when the light source is not energized are accumulated on another common storage site. When performing a computation on the basis of an electrical readout of one set of stored signals and another electrical readout of another set of stored signals, the different characteristics of the different storage site prevent inaccurate results.
