摘要： In a subband coding device for coding a digital device input signal which is a one-dimensional or a two-dimensional signal, a single coding circuit is used instead of a conventional combination of coders and a multiplexer. The coding circuit is for coding subband samples of different frequency bands in each sample group across the frequency bands, as by starting from a lowest frequency band and ending at a highest frequency band or reversedly, and preferably with attention directed to correlation which the subband samples have between two adjacent frequency bands. Zero-level components of the subband samples are preferably run-length coded. When the subband samples of each sample group have a tree structure including subtrees, the subband samples are preferably scanned from a subtree to another subtree either starting at or ending at the subband sample of the lowest frequency band.

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： The present invention relates to a digital watermark insertion system that automatically calculates a digital watermark strength suitable to an input image and inserts a digital watermark into the image. The image categorizing section 103 classifies input images and outputs category indexes. The storage device 101 stores digital watermark characteristic tables describing the correspondences between digital watermark strength, image-quality degradation degree and attack-resistant evaluation value by category index and selects a digital watermark characteristic table to be used according to an input category index. The digital watermark strength calculation section 100 outputs a digital watermark strength to the storage device, calculates an optimum digital watermark strength using an image-quality degradation degree and a resistant evaluation value output from the storage device 103 and constraint information input by an user. The digital watermark insertion section converts embedded data into a digital watermark and inserts the digital watermark in an input image with the strength of an input optimum digital watermark strength, thus outputting a watermarked image.

摘要： The invention provides a reversible eight-element discrete cosine transform system which can be realized with a practical circuit and provide transform values proximate to those obtained by actual eight-element discrete cosine transform. In 4×4 matrix transform which appears when eight-element discrete cosine transform is decomposed in accordance with a high speed calculation method, transform values (X1, X7, X3, X5) are divided into (X1, X7) and (X3, X5), and if (X1, X7) are determined, then possible values as (X3, X5),are limited. This is utilized for quantization of the elements. (X1, X7) are quantized with step sizes of k1 and k2 by operators to obtain quantization values (Q1, Q7). Meanwhile, from (X3, X5), global quantization values are obtained by a quantizer using a conventional reversible quantization technique while local quantization values are obtained using a second numerical value table, and quantization values (Q3, Q5) are obtained from the values of the gloval quantization values and the local quantization values. Then, an eight-element discrete cosine transform system is constructed by a combination of reversible transform quantization of a 4×4 matrix and conventional reversible transform quantization of a 2×2 matrix.

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： A broadcast verification system is provided which enables broadcast verification to be performed by a third party being independent of a broadcasting station, without being assisted by another, at low costs and to be reported to a client.The client submits CM (Commercial Message) images to the broadcasting station and registers feature descriptors in a database. When the broadcasting station broadcasts the CM images in accordance with a contract, a receiving device in a checking base extracts contents from received broadcasting waves and a checking section compares feature descriptors of the contents with that of contents stored in the database. When there is coincidence between them, the checking section transmits comparison results to an aggregating section which creates a report including broadcast time, broadcasting channel, broadcasting state and submits it to the client. A broadcast verifying agent receives a broadcast verification entrusting fee.

摘要： A motion compensation circuit comprises finite impulse response (FIR) filters divided into N groups according to N subbands of input video signal samples. One of the FIR filters of each group receives a delayed version of the subband of the group, and the remainder of the group receives a delayed version of one or more of the subbands which are adjacent to the subband of the group. Each FIR filter has tap-weight multipliers controlled in response to an estimated motion vector for shifting sample points of each subband. N adders are provided corresponding respectively to the N groups of FIR filters for summing the outputs of the FIR filters of the corresponding groups to produce N motion compensation signals.

摘要： On subjecting a digital video signal of successive pictures to redundancy reduction coding, a mode signal is produced which indicates, as the redundancy reduction coding, a selected one of interframe coding and intraframe coding. The digital video signal is selectively subjected to the selected one of the interframe and the intraframe coding in response to the mode signal. A particular picture element of a current picture is subjected to the intraframe coding when the mode signal indicates that the particular picture element should be subjected to the interframe coding and that a corresponding picture element of a following picture following the current picture should be subjected to the intraframe coding. The mode signal and results of the interframe and the intraframe coding are multiplexed into a multiplexed signal. When a motion-compensated coding is used instead of the interframe coding, a specific picture element of the current picture is subjected to the intraframe coding when the mode signal indicates that the specific picture element should be subjected to the motion-compensated coding and furthermore when the specific picture element has no relation to a movement represented by each of motion vectors which are used in carrying out the interframe coding on the picture elements of the following picture.
