摘要： An image processing apparatus (5) that corrects an input image signal (Xin) pixel by pixel to generate a corrected image signal (Xout), having a filtering means (2) that determines a luminance distribution of a pixel to be corrected and pixels neighboring the pixel to be corrected, a correction gain calculation means (3) that determines the correction gain of the pixel to be corrected, and an operation means (4) that uses the correction gain determined by the correction gain calculation means to perform an operation on the input image signal pixel by pixel. With this simple configuration, the dynamic range of the input image can be appropriately improved.

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.
摘要翻译：当数字视频信号被压缩时，预测所得到的数据量，并且控制量化电平以获得恒定的比特率。通过计算标准偏差和非零系数的线性组合，或者通过计算相邻像素值之间的绝对差的和，或通过计算像素值的动态范围来进行预测。比特率也可以通过删除高频系数来控制。为了避免图像劣化，也可以根据小图像区域对量化噪声的灵敏度来控制量化级别。通过将区域划分成可以重叠的子块和计算每个子块中的统计量来确定灵敏度。为了减少运动估计所需的计算量，从亮度运动矢量导出色度运动矢量。

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.
