Abstract
An image processing apparatus determines a reference pixel position for each pixel by an interpolation calculation using the distortion correction values for representative pixels stored in a correction value storage unit, decides whether the distortion correction values used in the interpolation satisfy a predetermined condition, reads a plurality of pixel values from an image data storage unit according to values of their reference pixel position, determines first interpolation coefficients from a value of its reference pixel position, and determines the pixel value in the output image from the plurality of pixel values read and the first interpolation coefficients. The image processing apparatus determines second interpolation coefficients from said value of its reference pixel position and a predetermined function, and selects, according to the decision result, either the second interpolation coefficients or third interpolation coefficients for use as the first interpolation coefficients.
