摘要： In encoding, index information indicating a group of coefficients that minimizes the sum of the error between the value of each sample and the value is obtained by multiplying the quantized value of each of a plurality of samples by a coefficient corresponding to the position of the sample. The coefficient is selected from a plurality of groups of predetermined coefficients corresponding to the positions of the samples. In decoding, a plurality of values corresponding to an input vector quantization index are obtained as decoded values corresponding to a plurality of sample positions. With the use of a group of predetermined coefficients corresponding to the plurality of sample positions and indicated by input index information, the values obtained by multiplying the decoded values and the coefficients, corresponding to the sample positions are output.

摘要： An effective image area can be properly corrected in accordance with the quantity of light from an irradiation unit by selecting, as the effective image area, pixels having light quantities more than or equal to a threshold value that allows accurate acquisition of a surface image of a recording medium, on the basis of a light quantity distribution of the light from the irradiation unit. This reduces the influence of mounting accuracy of the irradiation unit, and allows the recording medium to be identified accurately.

摘要： A quantized normalization value and a normalization-value quantization index corresponding to the quantized normalization value are obtained, the quantized normalization value being obtained by quantizing a normalization value that is a value representative of samples. If a difference value that is obtained by subtracting a value corresponding to the quantized normalization value from a value corresponding to a magnitude of a value of each sample is positive and if the value of each sample is positive, the difference value is set as a quantization candidate. If the difference value is positive and if the value of each sample is negative, a value obtained by inverting positive/negative of the difference value is set as the quantization candidate. The plurality of quantization candidates respectively corresponding to the plurality of samples are collectively vector-quantized, and a vector quantization index is thus obtained and output. Sign information is output, the sign information expressing positive/negative of each sample that does not make the difference value positive, among the samples. Accordingly, encoding and decoding techniques capable of reducing musical noise and the like can be provided.
