PROBLEM TO BE SOLVED: To form a three-dimensional image with a simple and a low cost configuration. SOLUTION: The device is provided with at least a set of light sources 12R, 12G, 12B of a point light source type arranged substantially in a line in which addressing is individually possible, and an optical image-formation means 20 to image-form light emitted from each light source to a condensed beam, then to deflect-the condensed beam in the prescribed individual deflection direction. The device performs the sequential addressing of each light source. |
