This invention is directed at a video stabilizer which removes non standard AGC pulses added to a video signal for inhibiting the making of acceptable video recordings of the video signal which includes filtering out the horizontal synchronizing signals form the composite synchronization signal, while passing the vertical synchronizing signal; differentiating the vertical synchronizing signals; applying the differentiated signal to a first electronic device; turning the first electronic device o...

A video printer for making a print of main frames of different scenes of a video motion picture or animation recorded on a video tape, video floppy or the like can detect automatically one frame for each scene. For detecting a scene transition, the video printer is provided with a frame comparing device for comparing video signals of every pair of two adjacent frames reproduced time serially to provide a signal representative of the degree of correlation thereof. A judging device determines that...

A video system comprising a video camera and a recording device to record video signals obtained by the video camera, wherein the recording device starts functioning with a plurality of different delay times based on operating instructions to the video camera.

A video projector utilizes a reflective liquid crystal light valve of the active matrix system and a polarizing beam splitter. An active matrix array circuit of the light valve has pixel electrodes arranged in a matrix mattern. The pixel electrodes each has a reflective surface for reflecting a light beam and protects corresponding switch elements from the light beam. There are provided at least two switch elements for each of the pixel electrodes so as to enhance the redundancy of the array cir...

This invention has an object to provide a video printer capable of recording both a video by a movie projector and a photograph, a picture on a video tape. In this invention, the video printer comprises a lens attached to one end of a box for projecting a video, a light source mounted in the box, a holder formed at the other end of the box and formed with a glass surface at one end thereof for a photograph or a picture, and screen means opened or closed at a member having a glass surface and ano...

The present invention relates to a maneuverable, foldable and transportable video cart, particularly for use in the video filming of subjects on location. The video cart, pertaining hereto, is of such a designed function that it can be placed in a folded and non-filming position available for transporting from studio to filming location. At the filming site, the video cart of this invention can be readily unfolded and arranged in its filming position. The video cart is equipped with wheels for m...

A video memory, for use with a video tape recorder, a television receiver of the like to process a picture, is simplified and can achieve the functions of a time base corrector, a noise reducer and a comb filter, so as to considerably improve the quality of a video picture. A frequency converting circuit for use with the video memory includes a comparator for comparing first and second address signals and an address correction circuit connected to receive an output signal from the comparator. Wh...

A video system comprising a video camera and a recording device to record video signals obtained by the video camera, wherein the recording device starts functioning with a plurality of different delay times based on operating instructions to the video camera.

A video telephone including a display unit and a handset for transmitting and receiving both audio signals and digital data representative of video images over an established communication channel across a conventional telephone line. The display unit includes a receiver for receiving signals from the handset and a display screen for displaying a video image. A microprocessor is connected to the receiver and the display unit. A data storage device for storing data representative of an image and ...

An encoder system includes an internal counter (PTS or presentation time stamp counter). The counter provides information which enables the encoder system to resynchronize itself in the event synchronization with the video input stream is lost. Preferably, the counter is implemented in software. The encoder system also include a comparator (preferably implemented in software). The comparator is able to determine if particular regions of the input video stream have been captured at an expected ti...
