Abstract

A method and apparatus are provided to controllably compensate for distortions in an image produced by an LPD, where the distortion arises from the shape and / or angle of the viewing surface relative to the LPD. For example, the LPD can determine the angle of the viewing surface relative to the LPD and then adjust the horizontal and vertical scan mechanisms to return the image to its original configuration, such as rectangular.

Description

technical field [0001] The present invention relates generally to electronic displays and, more particularly, to laser projection displays used to compensate for distortion in laser projection displays. Background technique [0002] In the field of image projection, any of a wide variety of distortions may appear on the projected image due, at least in part, to the shape and angle of the viewing surface relative to the angle at which the image is projected. For example, if the projector is placed at an angle relative to the viewing screen, the image has a trapezoidal shape that differs from its traditional rectangular configuration. Likewise, rectangular images projected onto curved surfaces will be distorted. So, the problem is complex and none of the proposed solutions have been successful in restoring the image to its desired rectangular structure without losing image resolution and without cumbersome and complex optics. [0003] It is an object of the present invention...
