摘要:
A range finding device of a construction, in which, at the time of receiving first and second images of an object to be formed by a range finding optical system with a relative positional parallax corresponding to the object distance into first and second photoelectric light receiving elements, respectively, these images are shifted on the light receiving surfaces of the respective first and second light receiving elements by a vibrating optical device at a same cycle and same phase to thereby scan these first and second images by the first and second light receiving elements; image scanning signals on the first and second images to be obtained at this time are converted into digital values; thereafter, these values are stored in the first and second storing devices where the coincidence and non-coincidence of these digitalized image scanning signals are detected by means of a coincidence detecting device, while one of these image scanning signals are relatively shifted bit by bit with respect to other image scanning signals; and the shift bit quantitites required until the image scanning signals of the same bit numbers of these first and second images may become optimumly coincided, thereby finding out the object distance from the shift bit quantities at the time.

A device using signal integration and storing type image sensing means having the functions of generating an electrical signal corresponding to the integrated amount of incident light, storing it, and putting out said stored signal in time-sequential or -seriated manner. This device is provided with control means for controlling the signal integrating and storing operation of said image sensing means. The control means is arranged to control the signal integration and storing operation of the sensing means so that the signal integrating and storing cycle of the image sensing means is made equal to an integer multiple of about 50 mm sec.

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.

A recording system comprises an image pick-up recording device to record the picture information obtained through the image pick-up on a recording medium by a recording head; and a control device to change the relative location of the head and the medium after the information of one picture has been recorded in a predetermined location on the medium and to prevent the next picture information from being read out during the period of time until the completion of that displacement. The recording sytem may be provided with a memory for the picture information and a control device for allowing part of the picture information to be recorded in the selected portion on the medium. The control device also permits the other portion of the picture information stored in the memory to be recorded in the other portion on the medium after changing the relative location of the head and the medium.
摘要:
A trigger device for an electronic flash so designed that a shutter control signal produces a signal for opening and closing an electromagnetically driven shutter and a timer for delaying the shutter control output signal are provided in such a manner that the flash emits the light in response to the shutter closing operation control signal or the delayed signal from the timer which is later than the other when both signals are produced.

Disclosed is a video conference system including a video camera for imaging participants in a conference, a registration unit capable of registering a plurality of pieces of position information indicating directions of the positions of the participants in the conference, a changing unit for changing the imaging direction of the video camera on the basis of the position information, a memory unit capable of storing a plurality of image data corresponding to the individual imaging directions set by the changing unit, and a synthesization unit for synthesizing the image data stored in the memory unit into image data currently being obtained by the video camera in correspondence with the position information registered in the registration unit.
摘要:
An image pick-up device using image pick-up device having a photoelectric converting portion and a memory portion for storing therein image information formed in the converting portion, and a light source for illuminating an object to be photographed, has an inhibiting device for inhibiting the light emission of the light source while the image information in the photoelectric converting portion is transferred to the memory portion. The amount of accumulation after the accumulation of image signals in the image pick-up device is started is discriminated and control is effected such that the illuminating light source is caused to functionally act when the amount of accumulation does not reach a predetermined amount.

A distance measuring device comprised of a system which projects infrared rays on a distant object, a light receiving optical system positioned at a prescribed base length from the infrared ray projecting system; a sensor of the signal storage type including an array of light sensitive elements arranged in a position which approximately coincides with the imaging plane of the light receiving optical system. A control means arranged to cause the sensor to perform a storing action under a first condition in which the infrared ray projecting system is allowed to operate and also under a second condition in which the infrared ray projection system is not allowed to operate, and digital computing means designed to detect a difference between output signals of every light sensitive element respectively produced under the first and second conditions and to detect a distance to the distant object on the basis of the results of detection of the difference between these signals.

A clear print image is obtained from a moving image. A switch (66) for selectively supplying an output from a moving image input camera (60) or a still image input picture/image camera (64) to a still image coding circuit (68) is arranged in an image transmission terminal device (50). An output from a still image decoding circuit (82) is connected to a printer (86) in an image receiving terminal device. When a print image of an image photographed by the camera (60) is required, a moving image print indication is made at an operation panel (88). A data control circuit (76) supplies a switching signal for the switch (66) to the terminal device (50) to switch the switch (66) to the output side of the camera (60). The output from the camera (60) is sent through a still image processing system (68, 70, 72, 74, 76, 82). A clear, high-quality image signal of the image photographed by the camera (60) is supplied to the printer (86).
摘要:
A synchronizing pulse signal generation device separates horizontal and vertical synchronizing signals from a video signal; generates a clock signal which is phase locked relative to the phase of the horizontal synchronizing signal; and generates, by using the clock signal, a synchronizing pulse signal which is phase locked relative to the vertical and horizontal synchronizing signals.
