Abstract
A demosaicing unit interpolates mosaic image data of each pixel of interest so as to reproduce colors missing at each pixel by interpolation using neighboring pixels. In the demosaicing unit, an interpolation unit performs an interpolation process in a plurality of prescribed directions using neighboring pixels in the prescribed directions. An evaluation unit evaluates image data in each prescribed directions interpolated by the interpolation unit. A spurious resolution area judgment unit judges whether a pixel is in a spurious resolution area, on a pixel-by-pixel basis, based on a saturation detected from image data subjected to an interpolation process performed so as to preserve an edge component. An image generation unit selects image data to be interpolated for each pixel based on a result of the evaluation by the evaluation unit and a result of the judgment by the spurious resolution area judgment unit, and generates interpolated image data.
