    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： The present invention relates to a method and an apparatus for decoding double-encoding codes in which the information to be decoded comprises a first data and a second data. The operation for decoding double-encoding codes is achieved through two stages. A decoder of the first stage checks the first data, and when an error is found in the first data, all symbols of the first data are assumed to be wrong. The first-stage decoder then adds an erasure flag to all symbols to generate erasure symbols. As a result, these erasure symbols include the symbols which are actually erroneous and those which are correct. A decoder of the second stage is used to perform an error correction on the second data. For this purpose, the second-stage decoder detects the number of erasure symbols which are contained in the second data and which are actually erroneous. If the number of actually erroneous symbols does not exceed the maximum number of correctable symbols which can be corrected by the decoder of the second stage, the error correction is effected; otherwise, the decoder detects an error without conducting the error correction.

    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.

    摘要： Here is disclosed an information recording and reproducing apparatus comprising a multi-phase quadrature angular modulator for subjecting a signal to be written on a recording medium to multi-phase quadrature angular modulation to generate a modulated signal expressing information in phase difference and frequency difference, a quantizer for generating a discrete signal by making discrete the amplitude of the modulated signal generated by the quadrature angular modulator with reference to a certain level, a write head for writing the output signal of the quantizer onto the recording medium, a read head for reading information written on the recording medium, a read compensate circuit for compensating the phase and amplitude of a signal readout of the read head, and a multi-phase quadrature angular demodulator for demodulating a signal supplied from the read compensate circuit by subjecting it to multi-phase quadrature angular demodulation. By expressing information to be recorded in phase difference or frequency difference, it is made possible to record or reproduce the information at the varying timing of amplitude, and the bit inversion interval can be controlled by regulating the timing of amplitude variation.
