摘要： Parity bits (check bits) having a relatively high redundancy are added to upper significant bits of a digital signal, and parity bits having a relatively low redundancy, are added to the lower significant bits of the digital signal. The signal and the parity bits are recorded on a recording medium. The position of an error in a data block group of the lower bits reproduced from the recording medium is estimated as existing in a block in which the error is detected by the check of the data block group of the upper bits, and in the blocks preceding and subsequent to the former.This error correction method is most suitable for a recording and reproduction system of digital video signals.

摘要： The present invention relates to a color imaging device which suppresses false color signals appearing in an area where the difference of brightnesses is great in the horizontal or vertical direction.When the correlation between picture elements adjacent in the vertical direction is little and the false signal appears in a boundary part in the vertical direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the horizontal direction. On the other hand, when the correlation between picture elements adjacent in the horizontal direction is little and the false signal appears in a boundary part in the horizontal direction, the false signal is detected, whereupon a color signal is demodulated by utilizing the correlation between the signals of picture elements in the vertical direction.As a result, the moire phenomenon attributed to the false color signals can be conspicuously reduced.While embodiments of the present invention refer to color imaging devices which employ MOS type solid-state imaging devices, the invention is also applicable to an imaging device which employs CCDs and a color image pickup tube which separates colors by means of a mosaic color filter.

摘要： An apparatus for recording or reproducing codes resulting from digitalizing a picture signal on or from a video tape recorder includes a device for correcting code error produced due to interference in the course of recording or reproducing process. The pixel codes succeeding to one another in time are divided to high-order and low-order bit-blocks, respectively, wherein the high-order bits are used to constitute a pseudo pixel code which is then added with a pixel error correcting code. The pixel code consisting of the high-order bits is added with a bit error correcting code before being recorded. In reproduction, error correction can be realized at higher rate with the aid of the correction codes to improve the quality of reproduced picture.

摘要： A magnetic digital storage method and system which can improve a recording density and can reduce a cross-talk upon reproducing. An inputted high-speed digital signal is converted to a plurality of low-speed digital signal sequences by a recording circuit and each of the low-speed signal sequence is recorded onto a plurality of adjacent recorded tracks of a recording medium by integrated parallel recording heads. One servo signal is commonly recorded to the plurality of recorded tracks. Further, when recording the digital signal to the adjacent recorded tracks of the recording medium, a delay of a signal that is applied to each recording head is adjusted such that the phases of magnetic transition points given by the recording signal in the adjacent recorded tracks are not identical in the circumferential direction.
