PROBLEM TO BE SOLVED: To provide a projection device and projection method with which a complementary image can be easily projected at any position of an image in a principal part.SOLUTION: A projection device includes an image forming unit 100, a dividing mirror 40, and a screen 50. The image forming unit 100 is formed to be capable of projecting images from a projection lens 135. The dividing mirror 40 includes a first mirror 41 and a second mirror 42; the mirrors are formed to have a reflection surface with a changeable inclination angle; and the angles are controlled. The image projected on the first mirror 41 and second mirror 42, of the images projected from the image forming unit 100, can be moved on the screen 50 by changing the inclination angle of the reflection surfaces of the first mirror 41 and second mirror 42. |
