Abstract
A frame correction method includes the following steps. Firstly, a correction frame is projected, wherein the correction frame has a number of original-boundary contour points. Then, in the first boundary contour adjustment, in response to a position adjustment of the first contour-adjusted one of the original-boundary contour points, correspondingly adjust the position of at least one symmetrical one of the original-boundary contour points, wherein at least one symmetrical one and the first contour-adjusted one are symmetrically disposed. Then, in response to the position adjustment of the first contour-adjusted one, a number of first new boundary contour points and a number of first open correction points are added.
Claims20
A frame correction method, comprises:
- projecting a correction frame, wherein the correction frame has a plurality of original-boundary contour points;
- in a first boundary contour adjustment, in response to a position adjustment of a first contour-adjusted one of the original-boundary contour points, correspondingly adjusting a position of at least one symmetric one of the original-boundary contour points, wherein the at least one symmetric one and the first contour-adjusted one are symmetrically disposed;
- and
- in response to the position adjustment of the first contour-adjusted one, adding a plurality of first added-boundary contour points and a plurality of first open correction points.
A projector, comprises:
- a projection module configured to project a projection image, wherein the projection image has a plurality of original-boundary contour points;
- and
- a processor configured to:
- in a first boundary contour adjustment, in response to a position adjustment of a first contour-adjusted one of the original-boundary contour points, correspondingly adjust a position of at least one symmetric one of the original-boundary contour points, wherein the at least one symmetric one and the first contour-adjusted one are symmetrically disposed;
- and
- in response to the position adjustment of the first contour-adjusted one, add a plurality of first added-boundary contour points and a plurality of first open correction points.
