Abstract
An image processing apparatus includes an edge strength calculating unit that sets, as an input image, a pixel number reduced image obtained by reducing the total number of pixels of an image captured by an imaging element and calculates edge strengths of a plurality of directions in a unit of a pixel block; an interpolated-pixel value calculating unit that calculates interpolated-pixel values as smoothing components of the plurality of directions in the pixel block; a weight calculating unit that calculates weights for the interpolated-pixel values as the smoothing components of the plurality of directions based on the edge strengths; and a blending processing unit that calculates a pixel value of the correction object pixel which is the center pixel of the pixel block by performing a blending process by weighted addition of the interpolated-pixel values, which are the smoothing components of the plurality of directions, and the calculated weights.
