Abstract
An exemplary aspect of the invention can provide a method for easily adjusting the distortion of a projected image. 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 can be 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 can be 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 can be 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. An outline corresponding to the amount of distortion correction beyond the predetermined range can be made differently from an outline corresponding to the amount of distortion correction within the predetermined range, so that each is identified.
