Abstract
First imaginary screen outer peripheral line is calculated supplementing one side that is undetected with one side of an outer peripheral line of image light that is calculated, an imaginary screen aspect ratio that is an aspect ratio of an area defined by the first imaginary screen outer peripheral line is calculated, whether the imaginary screen aspect ratio is more vertically oriented than a first ratio or not is determined. When a result of the determination of the imaginary aspect ratio is more vertically oriented than the first ratio, the imaginary screen aspect ratio is changed to second ratio that is different from the first ratio, and the one undetected side is calculated according to the second ratio, and the first imaginary screen outer peripheral line is corrected and a second imaginary screen outer peripheral line is calculated.
