摘要： A solid-state color imaging device is provided including a plurality of photosensors which are arrayed in horizontal and vertical directions, and a mosaic color filter made up of filter elements arranged in correspondence with the respective photosensors. The mosaic color filter is arranged such that any group of four adjacent filter elements comprises a first filter which is made for panchromatic transmission, a second filter which is selected from among a first spectral region-transmitting filter, a second spectral region-transmitting filter and a third spectral region-transmitting filter respectively exhibiting different transmission characteristics, and third and fourth filters which are made of complementary color filters which transmit the transmission light component of the second filter and which have transmission components different from each other. The solid-state color imaging device also has means for simultaneously reading out optical signals of two of the photosensors adjacent in the vertical direction, and means for adding the two output signals.

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： An improved 8-8 mpping table system in digitally and magnetically recording video signals. Video signals coded into natural binary codes consisting of 8 bits are converted into different binary codes consisting of 8 bits constituted by patterns in which a continuous number of the 1's or the 0's does not exceed a predetermined number. In these codes, the continuous number of the 1's or the 0's is so limited that a maximum magnetization interval is reduced in magnetically recording the signals. Therefore, erroneous code is prevented from occurring in reproducing the signals.

摘要： In one embodiment, a symbol error correction encoder effects block interleaving on recording data and thereafter performs first error correction encoding on the recording data. Next, a symbol error correction encoder performs encoding on the whole block. A reproducing processing circuit outputs likelihood information of respective bits. A first error correction decoder corrects a random error produced upon recording and reproduction, using the likelihood information. Since it is possible to make an improvement in performance with respect to the random error by repetitive decoding at this time, the post-correction data is returned to the reproducing processing circuit. After the completion of such repetitive processing, the data is digitized and subjected to an error correction in symbol unit by a hard determination, and outputted to a symbol error correction decoder.
