Patent ID: 8777420

Claim:
A projector comprising: a light source configured to emit light; a light modulation section configured to modulate the light in accordance with an image data; a projection system configured to project the modulated light onto a projection surface as a projected image; a target display area determination section configured to determine a target display area within a reference display area, the reference display area corresponds to a possible range within which the target display area can be displayed; a target formation area determination section configured to: determine a relationship between the reference display area and a reference formation area, the reference formation area is an area on the light modulation section to display an image on the entire reference display area; and determine a target formation area based on: (1) the relationship between the reference display area and the reference formation area, and (2) the target display area determined by the target display area determination section; and a correction application section configured to generate corrected image data for supply to the light modulation section by correcting any provided original image data to be formed in the light modulation section so that a distortion-free image is displayed on a projection surface.
