An image conversion apparatus calculates, based on a first value for obtaining first coordinate values in a second image before first conversion, which correspond to coordinate values of one pixel in a first image after first conversion, a second value for obtaining second coordinate values in the second image, which correspond to coordinate values of a pixel adjacent to the one pixel in the first image. The apparatus converts the second coordinate values into third coordinate values for second conversion of converting a third image into the second image and converts the third image into the first image. In the calculation of the second value, addition or subtraction using a constant and a result of the calculation is iteratively executed for sequentially outputting values corresponding to results of multiplication of coordinate values of each pixel in the first image and the constant. |
