ABSTRACT:
Provided is a display method used for a display device that displays a design image and a pickup image in a superimposing manner, including: a distortion correction process of correcting distortion of the pickup image; an alignment process of aligning a position of the design image and a position of the pickup image; and a display process of displaying the design image and the pickup image in the superimposing manner. In the distortion correction process, the distortion of the pickup image is corrected so that a quadrangle formed by connecting four points on the pickup image becomes a rectangle in parallel with a vertical axis and a horizontal axis, the four points specified on the pickup image corresponding to four points on the design image which are connected to form a rectangle in parallel with the vertical axis and the horizontal axis. In the alignment process, the position of the design image is aligned with the position of the pickup image by carrying out at least one of right-left reversal, top-bottom reversal, shift, rotation, enlargement, and reduction, with respect to at least one of the design image and the pickup image.
