IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM |
摘要 |
<p>The present invention provides an apparatus and a method to perform an interpolation process of a color mosaic image generated through an imaging process by a single-plate color imaging element. The color mosaic image generated through the imaging process by the single-plate color imaging element is input, estimation is performed for a pixel value low frequency component and a noise high frequency component corresponding to a pixel interpolation position, and calculation for a pixel value at the pixel interpolation position is performed by applying an addition result thereof. An edge-adaptive interpolation processing unit calculates a pixel value at the pixel interpolation position by using a pixel value of a reference pixel located in an edge direction. A blend processing unit calculates a final interpolation pixel value by blending the edge-adaptive interpolation pixel value and the addition result of the pixel value low frequency component and the noise high frequency component corresponding to the pixel interpolation position in accordance with flatness at the pixel interpolation position.</p> |
