摘要： A projector displays an image on a projection surface. The projector comprises a light source, an image formation panel, a zoom adjusting module, and a keystone correcting module. The light source emits light. The image formation panel forms in an image formation area of a panel surface an effective panel image for modulating light emitted by the light source into effective image light representing an image. The zoom adjusting module adjusts zoom level of a zoom lens for enlarged projection of image light. The keystone correcting module corrects trapezoidal distortion of the image displayed on the projection surface by means of forming the effective panel image in a revised image formation area, the revised image formation area being part of the image formation area of the panel surface. The zoom adjusting module adjusts the zoom level to a target zoom level in which a total projection area encompasses the projection surface and in which a perimeter of the total projection area contacts the perimeter of the projection surface at one or more contact points, the total projection area being an area onto which is projected image light corresponding to all areas of the image formation area of the panel surface. The keystone correcting module performs correction such that the perimeter of the revised image formation area contacts the perimeter of the image formation area of the panel surface at a point on the perimeter of the image formation area of the panel surface corresponding to the contact point of the perimeter of the total projection area with the perimeter of the projection surface.

摘要： The projector comprises an image forming panel that forms an effective panel image for modulating the light into an image light in an image forming area of a panel surface, and an image capturing unit for capturing a specific projection area wherein the image light corresponding to a specific area in the image forming area is projected. The projector calculates one or more edges of the outside perimeter lines of the screen and of the specific projection area by detecting plural points in a captured image. Based on the detection results, a post-correction image forming area is calculated, and trapezoidal distortion is corrected by forming the effective panel image within the post-correction image forming area. When only three or less of the four edges of the outside perimeter lines of the screen are detected, the projector calculates the post-correction image forming area based on the position and slope of the detected edge within the captured image.
