A method of transmitting TV signals comprises transmitting three-dimensional information representing three-dimensional shapes of a stereoscopic object from a plurality of view points, and image information of the stereoscopic object and two-dimensional information indicating a correspondence between points in a surface of the stereoscopic object represented by the three-dimensional information and the image information of the stereoscopic object, as TV signals.

Method and apparatus for transmitting television signals, method and

A video signal apparatus allows multiple pictures to be displayed. A plurality of input video signals are processed to produce a plurality of signals corresponding to a respective plurality of pictures. The plurality of pictures corresponding to the plurality of signals are displayed. At least one of the plurality of pictures which have been displayed is selected. First and second modifications are made to the selected picture. The first modification to the selected picture indicates that the selected picture is being provided with the second modification.

Multipicture video signal display apparatus with modified picture

A video display apparatus comprising a memory of fields for plural images, a device for judging whether even-number field or odd-number field, and a frame synchronizing device for reading and selecting fields, in which, if the input has one type of field only, these plural images are displayed simultaneously while keeping correct interlacing.

Video display apparatus for displaying plural images simultaneously on a

A video signal of one field is applied to a high frequency component measuring device which measures the high frequency component strength Q of the image of the video signal. The video signal of one field is also applied to a field memory. A look-up table memory carries a plurality of quantization tables each containing parameters. The parameters are aligned in a matrix format in the quantization table. The strength Q is used for selecting one quantization table which is appropriate for reducing the size of coded video signal. A JPEG compression device compresses the video signal from the field memory by DCT operation to produce compressed signal, which is an alignment of a plurality of coefficients aligned in a matrix format. The coefficients are divided by corresponding parameters in the selected quantization table to reduce the size of the compressed signal.

Digital video signal code size control apparatus

The present invention provides a useful video editing system capable of reading shot directly from an original source and preparing a master tape to which vide effects such as wipes are applied and a method thereof. The video editing system comprises a video storage device for storing video data which is composed of an array of a number of frames and which can be concurrently reproduced through two channels or more, a shot information storage device for storing shot information which designates the storage location of each shot to be reproduced in the video storage device, a shot link information output device for releasing shot link information as output which specifies a link order and a link method for the shots to be reproduced, a channel allocation determining device for determining, in accordance with the shot link information, to which of the channels each shot to be reproduced should be allocated and releasing it as channel allocation information, a shot reproduction control device for accessing the video storage device to read the shots to be reproduced from the determined channels in the determined order in accordance with the shot information, the shot link information and the channel allocation information, and an effects generator device for linking the plurality of shots of the plurality of channels, which are sent from the shot reproduction control device, in the determined link method and creating video effects to be applied to the linked shots.

Video editing system with auto channel allocation

A non-linear video editing apparatus having a randomly accessible image data storage unit, a FIFO, a video effects unit, and desired-shots storage unit. The image data from the image data storage unit and data transfer to the FIFO are controlled so that images are not interrupted during an editing operation. The apparatus dispenses with a great number of switches and manage with a FIFO having a small capacity.

System for non-linear video editing

An image processing apparatus is for exactly reproducing color originals. The apparatus includes a circuit for removing a ground color contained in an input color signal by forcibly changing an input signal having a level larger than a predetermined level to white. The apparatus may include a gamma correction circuit having therein a plurality of selectable gamma collection data. The apparatus may also include a circuit for producing a natural monochromatic signal from signals corresponding to three primary color signals R, G and B by performing an operation expressed as [(signal corresponding to R).times.2.sup.I +(signal corresponding to G).times.2.sup.I +(signal corresponding to B).times.2.sup.K ]/2.sup.L wherein I, J, K and L are integers and 2.sup.I +2.sup.J +2.sup.K =2.sup.L.
