摘要： A photometric circuit for a camera has a photo-electric conversion element arranged to measure light in the middle part of the angle of view of the camera and a plurality of photo-electric conversion elements arranged to measure light in the peripheral parts of the angle of view. Of these peripheral light measuring elements, the elements disposed symmetrically with each other relative to the middle part of the angle of view are paired and connected in series with each other. Further, the series circuits thus formed are connected in parallel with the middle light measuring element.

The quantity of electric charge on these areas varies with the quantity of light incident thereon. An electric charge storage stores the electric charges produced at the two converters and a control determines the operation of the light receiving areas of the photo-electric converters according to the electric charge information produced.

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： An image sensor causes a solid-state imaging device, at the scanning of an image, to release in succession a dark current signal generated in the solid-state imaging device and a scanning signal containing said dark current signal, subtracts said dark current signal from said scanning signal by a differential circuit to obtain an image signal corresponding to said image, and so regulates by means of an integrating time control circuit and in response to the level of said image signal, the image signal integrating time of said solid-state imaging device as that said image signal remains within a certain level range. In an improvement of the present invention there is further provided means for forcedly resetting the image signal integrating time to be determined by said integrating time control circuit to a shorter time in case the image signal reaches an inappropriate level while said image signal integrating time is fixed at a determined level without renewed control thereof.

摘要： Disclosed is an intermediate adapter to be used between the camera body and the photographing lens during close-up photography. A light beam splitter in the adapter housing projects part of the light from the lens to a sensor to produce an electric signal. An illumination device that lights a subject to be photographed is controlled by the signal produced by the light split by the light beam splitter. The beam splitter includes a diffraction arrangement that directs a portion of the light from the path to the film.

摘要： The present invention relates to a motion detecting device for detecting the relative motion rate or velocity between an object and an optical instrument in an exposure control system by which the exposure time, i.e. the shutter speed of the instrument is controlled in response to the relative motion rate or velocity. The motion detecting device is designed to detect the displacement ratio or speed of the position of the center of gravity of the light distribution of the object image on the imaging plane, whereby the danger for misdetection due to the periodical fluctuation of the object brightness can be profitably avoided, being possible to detect only the relative movement between the object and the instrument.
