摘要： An interframe video data coding and decoding apparatus utilizes a differential amplitude suppression circuit in combination with a block encoder and a motion detector to non-linearly suppress amplitude values of interframe differential block data based on a motion detection threshold value determined by an encoding control circuit. The determined threshold value is based on the amount of encoded data being stored in a transmission buffer memory. The suppressed amplitude differential block data is added to corresponding blocks in a frame memory to update the contents of the frame memory during each frame of input video data. In another embodiment, vector quantization encoders are utilized to transmit a motion vector index with encoded frame differential data. In yet another embodiment, a time integral circuit integrates a continuous input video signal series by frame and writes the integrated frame signal into one of two frame memories, while interframe coding is performed on data stored in the other frame memory. Two transmission buffers are provided so that transmission can occur simultaneously with writing of the encoded interframe data into the buffer, by alternating switched connections of the two buffers.

摘要： In an interframe adaptive quantization encoding apparatus to perform efficient encoding of video signals using vector quantization method, analog signals raster-scanned from the left to the right on the screen and from the upper side to the lower side are converted into digital signals, the digital signals per every m picture elements x n lines are made a block and the block data is subjected to mean value separation in a vector quantization encoder thereby input vector is formed, inner product between the input vector and output vector read from a code book ROM is estimated by an inner product operation circuit, and maximum value of the inner product is estimated by a maximum inner product detection circuit and made amplitude coefficient, thereby efficient encoding is performed. The efficient encoding data is transmitted to the transmission path by a transmission data buffer and at the same time threshold value of movement detection in the vector quantization encoding is controlled by a movement detection control circuit, and the encoding data supplied from the vector quantizer is decoded by a vector quantization decoder and the block data is reproduced, thereby the apparatus can be constituted without increasing the circuit scale.

摘要： A subnyquist sampling filter which results in less loss of picture resolution. An adaptive prefilter perform low-pass filter processing on a series of picture signals sampled in the form of a square lattice in a direction in which it has been determined that the degree of change of the picture signal at the periphery of an extracted picture element is a minimum. An adaptive interpolation filter performs interpolation processing on the picture signal obtained by subnyquist sampling with a subsampler the picture signal output from the adaptive prefilter in the direction where the degree of change of the picture signal level at the periphery of the abstracted picture elements is a minimum.
