摘要：

Usually there is only a single CCD sensor in digital still camera. The CCD data array is interpolated into R, G, B planes to construct a complete color image. The interpolation attenuates the high frequency signal of the image, so a sharpening filter is used to compensate for the effect of blur. Pixel artifacts like zipper effect etc. are introduced by the sharpening operation. This paper presents an even-number-size-mask band pass filter, which can restore the color image's high frequency signal with no zipper effect. An image processing technique based on the compensation filter is proposed and experiments show satisfactory results.
