A one-dimensional image is obtained by light modulation using a one-dimensional light modulation device 4 in which a plurality of pixels are arrayed in the form of a line. The obtained one-dimensional image is scanned by a light deflection unit 8 that performs scanning in a direction perpendicular to the array direction of the one-dimensional light modulation device 4, and projected by a projection optical system 6 that includes therein the light deflection unit 8, thereby forming a two-dimensional image. The aspect ratio of the obtained two-dimensional image is variable in accordance with an angle through which the one-dimensional image is scanned by the light deflection unit 8. |
