Zusammenfassung:The present invention prevents image quality degradation due to pixel enlargement even when using an increased angle of inclination on projecting an image obliquely from a laser scanning display device. A swing mirror is controlled so that the scanning line density in the vertical direction of a display section is uniform in accordance with information including the angle of inclination, the distance of projection, and the display size of the display device with respect to the display section. A lens control driver is controlled so that a collecting lens has a focal point on the display section in accordance with a scanning position in the vertical direction of the swing mirror. The swing mirror or an image correction processing unit is controlled so that a display size in the horizontal direction of a display image on the display section is uniform regardless of the scanning position in the vertical direction.
