    摘要: In a field/frame conversion system in which a field signal recorded on a track of a recording medium is repeatedly reproduced, a field signal delayed by 1/2 horizontal scanning duration and a directly provided field signal are alternately selected by a switch at each vertical scanning duration, and one of the field signals is formed by an arithmetic mean of a signal delayed by 1 horizontal scanning duration and a directly provided signal, to provide a frame signal, a flicker preventing circuit device in a field/frame conversion comprises a circuit provided in a front stage of an arithmetic mean circuit of the field/frame conversion system for bringing a gamma value of the field signal to 1, and a gamma circuit provided in a rear stage of the arithmetic mean circuit for returning the gamma value of the field signal to its original value.

    摘要: A pair of parallel lead screws are meshed with a pair of helical racks provided on opposite faces of a movable stage slidable on a flat or cylindrical base plate. The pair of parallel lead screws are driven by a pair of electric motors independently of each other. One of the helical racks has teeth extending in a direction to intersect with the teeth of the other helical rack. By selecting the direction of rotation of the pair of lead screws independently, the direction of movement of the stage can be selected. The stage may be made of a pair of plates having the helical racks on the inner or outer faces of the plates.

    摘要: An X-Y movement mechanism, having right-handed and left-handed lead screws arranged in parallel with each other and drive sources for individually rotating the lead screws. Gears placed over nuts engage the lead screws, the gears having teeth coaxially with said nuts. A base plate, either flat or cylindrical has a stage slidable thereon. A rack is fixedly provided on the stage to engage the gears. The gears operate as a gear transmission mechanism permitting the rack to move in a direction perpendicular to the direction of the axes of the lead screws and in the direction of the axes of the lead screws.

    摘要: Original information is converted to digital signals and recorded on a digital signal recording medium such as a paper tape. The digital signal recorded on the tape or the like is converted to binary signals. A photosensitive material is fed in synchronization with the conversion of the digital signal to binary signals. The photosensitive material is exposed to light from a light source controlled in accordance with the binary signals. In a preferred embodiment of the invention, a print out typewriter is connected with the circuit which converts the digital signals to the binary signals to print out the information being recorded on the photosensitive material on an output sheet in the form of the original information.

    摘要: A magnetic disk contains video signals, representing an image, recorded on some tracks thereof in the form of digital signals, and also contains video signals, representing the same image, recorded on other tracks thereof. A recording apparatus receives analog video signals representative of an image, and converts the received signals into associated digital data to be temporarily stored in a storage. The data stored in the storage is read out to be recorded on tracks of the magnetic disk, and also to be converted into corresponding analog signals to be recorded on other tracks thereof.

    摘要: A sound recording apparatus for a still camera has a magnetic eraser head for erasing an audio signal stored in a track of a magnetic audio disc and a magnetic write head for writing an audio signal into the track a portion of which is just emptied by the erase head, during the rotation of the audio disc. Whenever a release button of the camera is depressed to write a video signal indicative of a still image into a track on a magnetic video disc, an audio signal associated with the still image and starting from the instant a predetermined time before the shot is written into the track on the audio disc. The predetermined time is the time period for which the track on the audio disc completes one rotation. Indentification data is recorded on each of the associated audio and video tracks after the audio or video signal to facilitate reproduction thereof.

    摘要: Sound associated with a scene which a still camera shot is picked up over a desired period of time starting from the instant which is a given time before the instant of depression of a release button of the camera. A shift register serves as a delay element for delaying an input time-serial digitized audio signal by the desired period of time, before the audio signal is written into an audio track of a magnetic disc which also has a video track for storing a video signal associated with the audio signal. During reproduction, one may hear the sound through a loudspeaker while watching the still picture displayed on a CRT or the like. The same sound may be reproduced repeatedly over a desired period of time.

    摘要: A video signal transmission system for an endoscope converts an electrical video signal produced by a solid state image sensor into an optical signal and transmits the optical signal to a control section through a fiber optic cable or like light carrying medium. Because the fiber optic cable used for the present invention transmits light indicative of a time serial signal from the solid state imaging sensor, it will be clear that the cable may be constituted by a single length of optical fiber and, in this respect, substantially differs from usual light carrying fiber bundles which are installed in general endoscopes as image guides for transmitting light images simply as light.

    摘要: In a method and apparatus for scanning tape including a recording medium with a scanning head, the head runs along the circumference of a circle having a central axis inclined by a predetermined angle with respect to a reference direction. The tape is guided along the elliptical circumferential surface of an elliptical cylinder with the longitudinal direction of the tape substantially perpendicular to the reference direction and the width direction of the tape substantially parallel to the reference direction, the elliptical cylinder being formed by a generatrix which includes a point on the circumference of the circle and is substantially parallel to the reference direction, while the point moves along the circumference of the circle. The tape is scanned with the scanning head while the scanning head runs along a portion of the circumference of the circle, the portion of the circumference of the circle being associated with a sector of the circle which sector has a radius substantially perpendicular to the reference direction and extends to both sides of the radius each by a substantially equal angle about the central axis.
