Abstract:
1. A method comprising: receiving image data for images to scan; generating light beams responsive to the image data; scanning the light beams according to a first pattern from a first edge to an ending edge to form at least one image, the first pattern being a wave pattern of scan lines such that amplitudes oscillate along a first axis as the beams progressively scan along a second axis, the second axis being substantially perpendicular to the first axis, wherein the first pattern has a first oscillation from the first edge that is directed in a first direction along the first axis; scanning the light beams according to a second pattern from a second edge to a second ending edge to form at least another image, the second pattern being a wave pattern of scan lines such that amplitudes oscillate along the first axis as the beams progressively scan along the second axis, wherein the second pattern has a first oscillation from the second edge that is directed in a second direction along the first axis that is opposite the first direction; configuring the image data to be n number of complete frames of video having m scan lines oriented along the first axis; configuring each complete frame to comprises a first subframe and a second subframe; assigning some rows of the m scan lines to the first subframe, wherein the first patterns correspond to the first subframe; and assigning other rows of the m scan lines to the second subframe, wherein the second patterns correspond to the second subframe; wherein a plurality of the first and second patterns of the light beams are alternatingly scanned.
