摘要： When a digital video signal is compressed, the amount of resulting data is predicted and the quantization level is controlled so as to obtain a constant bit rate. The prediction is made by computing a linear combination of a standard deviation and a number of non-zero coefficients, or by computing a sum of absolute differences between adjacent pixel values, or by computing a dynamic range of pixel values. The bit rate can also be controlled by deleting high-frequency coefficients. To avoid image degradation, the quantization level can also be controlled according to the sensitivity of small image areas to quantization noise. Sensitivity is determined by dividing an area into subblocks, which may overlap, and calculating statistics in each subblock. To reduce the amount of computation required in motion estimation, chrominance motion vectors are derived from luminance motion vectors.

摘要： An encoder counts the length of a data produced by the variable-length encoding, and time-division-multi-plexes information of the data length to the variable-length encoded data. Art encoder time-division-multiplexes information of the number of bits after a fixed partition used in the error-correction encoding to the initial bit of a variable-length code to a variable-length encoded data, and transmits them. An encoder, when a variable-length code for one symbol of the variable-length encoding extends over a partition used in the error-correction encoding, inserts a special code before the partition, or guarantees that the top of the partition is always at the top of the variable-length code. An encoder obtains the sum of fields and the difference between fields, and performs on these values the orthogonal transform to encode them.

摘要： A regression analysis is carried out (8) using pixel signals having a K-th spectral characteristic as the explanatory variable and pixel signals having an L-th spectral characteristic as the purpose variable in a plurality of pixel positions in an area neighboring a pixel of interest to obtain a pixel signal having the L-th spectral characteristic (9). Pixel signals obtained by low-pass filtering (7a-7c) of the output signals of an imaging device may be used as the explanatory variable and the purpose variable. The occurrence of false colors is thereby reduced when, in a group of pixel signals from pixels arrayed on a two-dimensional plane, each pixel having one of a plurality of spectral characteristics, the missing colors at each pixel position are obtained by interpolation.

摘要： An imaging device has color signal generating means (20) for outputting first color signals (R5, G5, B5) corresponding to incident light, and matrix operation means (67) for performing a matrix calculation including multiplication of the first color signals, color signals obtained by raising the first color signals to a power with a first constant (i) as an exponent, color signals obtained by raising the first color signals to a power with a second constant (j) as an exponent, and corresponding matrix coefficients to obtain second color signals (R6, G6, B6). The first and second constants and the matrix coefficients are determined so that the total characteristics of the color signal generating means and the spectral sensitivity characteristic correction means (6) approximate human chromatic curves or spectral sensitivity curves obtained by a linear transformation thereof. Good color reproducibility can be obtained without the use of an infrared cut filter for chromatic correction in the imaging device, and high-sensitivity imaging can be performed under dark conditions.
