Abstract:
Methods, systems and devices described herein improve vertical resolution at sides of a four cornered image produced by a scanning projector display device. In accordance with an embodiment, a first plurality of frames (e.g., odd frames) of the image are scanned back and forth from side to side starting at a first line level, in one of the corners. Additionally, a second plurality of frames (e.g., even frames) of the image are scanned back and forth from side to side, starting at a vertical offset level from the first line level, in the same one of the corners. The scanning of the first plurality of frames (e.g., the odd frames) is interleaved with the scanning of the second plurality of frames (e.g., the even frames).
