摘要： A pixel signal having a k-th spectral characteristic at a pixel interpolation position occupied by a pixel signal having an h-th spectral characteristic is generated from a set of pixel signals arrayed in a two-dimensional plane, each having one of a plurality of spectral characteristics, by calculating a difference between low-frequency components, corresponding to a degree of correlation between pixel signals having the k-th and h-th spectral characteristics in a neighborhood of the pixel interpolation position (8r, 8g, 8b, 24k, 24h, 26), calculating a non-correlation value corresponding to a degree of non-correlation between the pixel signals having the k-th and h-th spectral characteristics in the neighborhood of the pixel interpolation position (7r, 7g, 7b, 23k, 23h, 25), and obtaining the pixel signal having the k-th spectral characteristic at the pixel interpolation position by using the calculated difference and the non-correlation value (27, 28, 29). Accurate interpolation can be performed despite various different correlation relationships between color component values.

摘要： The difference between the output of a k-signal nonlinear low-pass filter (8g) and the output of an h-signal nonlinear low-pass filter (8r) is added (44) to the value of the h-th pixel signal (h(i, j)) at the pixel position of interest to obtain the k-th pixel signal (k(i, j)) at the pixel position of interest. Accurate pixel interpolation can be performed with good noise immunity, even at locations where the color signals are uncorrelated.
摘要翻译：将k信号非线性低通滤波器（8g）的输出与h信号非线性低通滤波器（8r）的输出之间的差值（44）加到第h个像素信号（ h（i，j）），以获得感兴趣的像素位置处的第k个像素信号（k（i，j））。即使在颜色信号不相关的位置，也能以良好的抗噪声性进行精确的像素内插。

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.
