PROBLEM TO BE SOLVED: To provide a method for easily adjusting the distortion of a projected image. SOLUTION: In adjusting the amount of distortion correction, values of the amount of distortion correction for a desired outline form to be formed based on desired positions are calculated after the desired positions are specified. Then whether all the calculated values of the amount of distortion correction are within a predetermined range where an original image is transformable into a distortion correction image is judged. If all the calculated values of the amount of distortion correction are within the predetermined range, the calculated values of the amount of distortion correction are set in an image distortion correction part. If a value out of the calculated values of the amount of distortion correction is beyond the predetermined range, outlines corresponding to at least part of the outline form of the projected image are produced, instead of setting the calculated values of the amount of distortion correction in the image distortion correction part. In the outline form, an outline corresponding to the amount of distortion correction beyond the predetermined range is made differently from an outline corresponding to the amount of distortion correction within the predetermined range, so that each is identified.
