Publication number: 20190018306Abstract: A projector including a light source apparatus, a modulation section, which functions as a light modulator that modulates light source light outputted from the light source apparatus, a projection system, which projects the modulated light modulated by the modulation section, and a focus adjusting section capable of adjusting the point where the modulated light is focused for each area of the modulated light. Defocus resulting from the shape of a projection surface and other factors can be suppressed, and an image can therefore be projected with the image brought into focus across a curved surface, an irregular surface, or any other surface.Type: ApplicationFiled: January 18, 2017Publication date: January 17, 2019Applicant: SEIKO EPSON CORPORATIONInventor: Hirofumi KASUGA
