摘要： PROBLEM TO BE SOLVED: To prevent an illegal color from being formed by distortion due to an aliasing error by providing a color legalizing device for connecting an adjustment factor turned into software with an input signal sample and forming a legalized color signal sample or the like. SOLUTION: A color legalizing processor 30 converts an illegal color pixel in a video image to a legal color value by applying the adjustment factor turned into software according to a legalizing method indicated and selected by control signals received from a connection conductor 18' and supplies it to a first input channel. The legalized color signal sample is supplied from an output channel 37 to a color format processor 38, re-converted to the 4:2:2 standard there and supplied to a signal copying device 40. The signal copying device 40 copies the legalized color signal sample of a 4:2:2 form and supplies it to first and second output 12 and 14.

摘要： PROBLEM TO BE SOLVED: To provide a digital video processor which is improved so as to obtain an output compressed video signal for indicating a continuous output picture by providing a motion vector processor for obtaining an output picture motion vector from an input picture motion vector. SOLUTION: A continuous motion vector of an IB input sequence (for example, a set of motion vectors a to d) is temporarily stored in each buffer memory 100. A timing and control unit (a motion vector processor) 110 receives data for specifying a position in an input and output frame sequences. A vector tester (a motion vector processor) 120 confirms which of the vectors that is possible to exist exists in input signals with regard to each block of an output frame. This information is transmitted to a vector calculator (the motion vector processor) 130 and an output vector is calculated according to one of the algorithms in accordance with which of source vectors is usable.

摘要： PROBLEM TO BE SOLVED: To mix two compressed video signals without degrading quality of a video image. SOLUTION: The video signal processing unit comprises a 1st input terminal that is used to receive a 1st compressed video signal A including a conversion parameter relating to pictures (I, P, B) of a signal Q and a DCT type and a motion vector, decoder D1 that decodes the 1st compressed video signal, of a 2nd input terminal that receives a 2nd video signal B to be coupled with the 1st video signal, a coupler 110 that couples the 2nd video signal with the 1st video signal to generate a coupled signal C, and an encoder E2 that re- encodes the coupled signal C and uses again the parameters (Q, DCT type and motion vector) to decode at least part of the coupled signal and obtained only from the 1st signal to maintain high quality of the pictures.

摘要： PROBLEM TO BE SOLVED: To provide a method that generates a best substitute value in the case of correcting a data error subject to wavelet transformation. SOLUTION: Data compressed by the data compressor including a wavelet transformation circuit 580 are stored in, e.g. a DVTR 3. The compressor is provided with a correction data generating means 5, which generates correction data to depict an optimum correction form to be used when the data are lost during reproduction. Various correction techniques are employed, including transformed data that are frequency-converted among the converted data and the error is corrected by using a high pass filtering. The corrected data are recorded on tracks different from those for relating data.

摘要： Apparatus for frequency-separating input image data, the apparatus comprises a data buffer (200,210); a multi-stage filter (230) for performing successive spatial filtering operations on input image data, the multi-stage filter having: (i) a first filtering stage (110) for frequency-separating the input image data into image data representing at least two spatial frequency bands; and (ii) one or more subsequent filtering stages (120,130) for receiving a subset of image data output by the preceding stage and frequency-separating that image data into image data representing two or more spatial frequency bands; in which data output (2,3,4;1.2,1.3,1.4) by each stage which is not part of the subset of the image data to be filtered by a subsequent filtering stage is supplied to the data buffer (200,210); and means (220) combining image data output by the last of the filtering stages and image data buffered in the data buffer.
