Abstract
Light from a light source is processed on the image display element by an image signal outputted from an image control section to be projected on the screen of a predetermined curved surface shape. When the light from the light source is processed by the image signal, the image control section processes an aberration shape of a projected image so as to coincide with the shape of a projection curved surface of the screen. Thus, a desired image can be clearly projected on the screen having the curved surface shape.
