Electronic alignment of primary color pixels in a scanned display

摘要

An image generation apparatus provides correction for color offsets. Color offsets may be caused by misalignments in laser diodes or optics assemblies in a laser projector. The offsets may be measured during or after manufacture of the laser projector. An image buffer is responsive to the offset data to translate each color plane separately. The image buffer may include separately addressable portions for each color. Further, variable delay elements on the output of the image buffer may provide color offset correction. Interpolation provides further offset correction.
