PROBLEM TO BE SOLVED: To provide an image processor which reduces distortion of an image due to an error and also reduces arithmetic operations. SOLUTION: When an enlargement/reduction rate is specified for an image, a pixel position calculation part 20 calculates the relative pixel positions of respective pixels constituting an image obtained through image processing according to the enlargement/reduction rate. A pixel value calculation part 30 calculates the pixel values of pixels corresponding to the calculated pixel positions through a specific interpolating process using the pixel values of the respective pixels of the original image included in a specific peripheral range. The pixel value calculation part 30 performs the interpolating process by using a sampling function which can be differentiated by a finite number of times and which has finite numerals. |
