<P>PROBLEM TO BE SOLVED: To provide demosaicking techniques that prevents the occurrence of signal undershoots and undershoots, which achieve an image capturing apparatus with higher image quality. Ž<P>SOLUTION: An image processing method calculates both vertical and horizontal luminance-chrominance difference components for each pixel of the mosaic input image. Next, the image processing method calculates an enhanced version of both vertical and horizontal luminance-chrominance difference components for each pixel of the mosaic input image. Then, the image processing method interpolates a G component for each of the original R and B components. Next, the image processing method detects a signal overshoot or undershoot in each interpolated G component and clamps each interpolated G component with a detected signal overshoot or undershoot to the closest neighboring original G component. Next, the image processing method interpolates missing R and/or B components in each pixel location of the captured image. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
