Abstract
An image processing apparatus for use in a display system comprises a display device for viewing image, and a geometric transformation module that is configured to precondition said image data with geometric transformations to thereby compensate for characteristics of the display system. The geometric transformation module may include a spatial transformation module for redefining spatial relationships between image pixels, an alignment and rotation correction module for repositioning image pixels, a focus correction module for correcting image defocus, a distortion correction module for correcting image distortions, and a multi-frame correlation module for performing motion-compensated frame rate conversion.
