摘要： Provided are an apparatus and method for executing sensitivity difference correction processing of an image signal, which is generated by a single plate-type image sensor through a color filter. The sensitivity difference correction is executed for Gr and Gb signals included the image signal, for example, an RGB signal, which is generated by the single plate-type image sensor through the color filter. A pixel value of a color filter unit which has the same color as a correction target pixel and is present in surroundings of the correction target pixel is acquired. An additional value is calculated by adding a difference between weighted mean pixel values "a" and "b" of two kinds of pixel groups "A" and "B" classified according to positions of pixels to the pixel value of the correction target pixel in which the weighted mean values correspond to distances of the pixel groups from the correction target pixel. A mean value of the pixel value of the correction target pixel and the additional value is calculated as a corrected pixel value of the correction target pixel.

摘要： 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.
