摘要： In a recording system, a sequence of image signals obtained from a sequence of images are used to generate and record a sequence of recordable signals on a read only memory. Efficient coding of the received sequence of image signals is carried out through the use of a given parameter which is adaptively and dynamically changed, preferably manually, through a parameter controller acting as the interactive device. The image signals are repeatedly subjected to the efficient coding process. The process uses a sequence of predictive signals to produce coded signals. The predictive signals are displayed on a monitor display device to be monitored by an operator. The operator changes the attributes of the parameter until an optimum image is obtained. The optimum parameter is stored on a magnetic tape. The image signals subjected to the efficient coding enable the production of a sequence of coded image signals which are recorded on the read only memory in synchronism with the optimum parameter, after the optimum image has been obtained.

摘要： In a reproduction system for use in reproducing a still image from a sequence of predictive error signals which is read out of a memory and which is preliminarily processed into a sequence of preliminary processed signals, an intermediate circuit interrupts the preliminary processed signals in response to an external command signal. In the intermediate circuit, the external command signal is resampled by a sequence of frame pulses in a resampling circuit into a resampled signal so as to close a gate circuit. No predictive error signal is sent to an adder circuit during absence of the gate circuit. An identical error signal is repeatedly produced as a sequence of reproduced signals to reproduce the still image.

摘要： In an image recording system for use in recording a sequence of coded signals on a recording medium, such as a CD-ROM in response to a sequence of image signals divisible into a succession of frames each of which is subdivided into a plurality of splits, the image signals are selectively subjected to interframe coding and intraframe coding in a coder to be coded into first and second error signals, respectively, under control of a coding control circuit. The intraframe coding may be carried out about a selected split at every frame, at every preselected period, or at predetermined positions of each scene. The second and the first error signals are rearranged into the coded signals by delaying the second error signal relative to the first error signal. Such a second error signal serves to reproduce an initial image on reproducing the coded signals and enables a reverse reproduction, a quick search, a high speed reproduction, and the like in a reproducing system.

摘要： In an image processing system for use in processing a sequence of image signals carrying a moving image, the image signal sequence is divided into a sequence of partial image signals each of which carries a scene subsequence defined by scene changes. A background signal generator determines a background portion of the moving image by monitoring a whole of each partial image signal and produces a background signal. The background signal is coded by a coder prior to a sequence of error signals resulting from predictive coding of each partial signal. During prediction of the background signal, the error signals may be rendered to zero in the coder. The background signal may be either determined at every picture element or at every block composed of a plurality of picture elements.

摘要： Time-varying picture signals of a plurality of channels are predictively coded by utilizing the interframe correlation and multiplexed at the transmitting side. The signals are separated for each channel, switched and selected for any channel for decoding at the receiving side after transmitted. When the receiving channel is switched over to other channel, a decoding error can occur and a reproduced screen can collapse since the predicting signals do not coincide with each other at the transmitting and receiving sides. Therefore, when the plurality of channels is selectively switched for decoding by using a single decoder, the refresh is repeated at predetermined time intervals in a short period of time by utilizing the intraframe correlation when the coding is carried out at the transmitting side so that, even if the channel is switched, an excellent reproduced screen may be immediately obtained. However, during the refresh, the compression ratio is reduced compared with that of the bit rate when a normal interframe correlation is carried out. Therefore, when the refresh is carried out, the amount of transmitted information for part or all of the channels other than the refreshed channel is compressed and, conversely, the amount of transmitted information for the refreshed channel is increased by the compressed amount and allocated. Thus, even if the channel is switched at the receiving side, the decoded image for the newly selected channel can be promptly reproduced.

摘要： In a transmitting system, a first multiplexer multiplexes first through M-th encoded digital video signals from encoders to produce a primary multiplex signal comprising cells which have channel codes, address codes, and cell data, where M represents an integer greater than two. Each of the cell data represents a part of one of the encoded digital video signals. Each of the channel codes indicates one of the encoded digital video signals. Each of the address codes indicates a position of one of the cell datum. A first demultiplexer demultiplexes the primary multiplex signal to produce first through N-th primary demultiplex signals, where N represents an integer which is less than M and greater than one. A second multiplexer multiplexes the first through the N-th primary demultiplex signals from the first demultiplexer through first through N-th transmitting paths to produce a secondary multiplex signal. A second demultiplexer demultiplexes the secondary multiplex signal datum in response to the channel codes and the address codes to produce the first through the M-th encoded digital video signals.

摘要： In an image communication system, an input image sequence is converted into a block-formatted sequence. A data compression signal indicative of the amount of moving blocks in the block-formatted sequence is generated to individually control a plurality of vector quantizers each having a particular frequency band and a memory containing output vectors. The output vectors of each of the vector quantizers is representative of inverse orthogonal transform of a code table of optimum quantized vectors in the particular frequency band, the optimum quantized vectors being orthogonal transform of interframe differential training image sequences. The output vectors is retrievable from the memory as a function of an interframe differential image sequence, or prediction error. Each vector quantizer selects one of the vectors retrieved from the memory which is nearest to the value of the interframe differential image sequence and generates an index signal representative of the selected vector, which index signal is encoded and transmitted to a destination. The outputs of the vector quantizers are processed by inverse vector quantizers to generate a predictive image sequence. The prediction error is detected as a difference between the predictive image sequence and the block-formatted sequence.

摘要： A multiplex transmission method and apparatus for motion picture signals. A transmission line constituted by transmission channels having different carrier frequencies is prepared. One of the transmission channels has a transmission rate almost equal to the long-term average of information generation speeds in encoding an arbitrary motion picture signal. The input motion picture signal is encoded by using inter-frame and intra-frame correlations, and encoded information is output for each image channel. The image channels are related in one-to-one correspondence with the transmission channels having the different carrier frequencies. When an image channel of interest, of the image channels, exhibits a large generated information amount representing the encoded information generation speed within a time interval determined by a predetermined transmission rate of the transmission line in advance, adaptive multiplexing is performed by dividing and distributing the encoded information of the image channel of interest to the transmission channels including the transmission channel of the image channel of interest. The encoded information divided/distributed by the adaptive multiplexing is transmitted for each allocated transmission channel.

摘要： On encoding a cluster and run sequence comprising clusters of non-zero signal elements and runs of zero signal elements into a code sequence with application of a compression encoding scheme selectively to the clusters and without application of the encoding scheme to the runs, a mode code is used to indicate application of the encoding scheme to each selected cluster and to represent a zero signal element next preceding the selected cluster in a next preceding run. In the code sequence, the mode code next precedes a succession of amplitude codes representative of the selected cluster and next succeeds a run length code preferably representative of that run length of the next preceding run from which the next preceding zero signal element is reduced. Alternatively, the mode code may indicate switching between application and non-application of the encoding scheme to partial sequences each of which starts with a cluster next succeeded by a run. In either event, a particular code is preferably used to indicate an end of each run. On decoding, the mode code is detected preferably with reference to the particular code to decide whether or not each amplitude code succession should be decoded according to an expansion decoding scheme which corresponds to the encoding scheme.
