Abstract
A scanning projector includes a scanning mirror that sweep a beam in two dimensions. Source image data is interpolated vertically, and the results are stored in a frame buffer. Each row of the frame buffer holds vertically interpolated pixel data that lies on a trajectory corresponding to a horizontal sweep of the beam. Pixel data in each row is then interpolated to determine display pixel data. At least one light source is driven with the display pixel data to produce the beam that is reflected by the scanning mirror.
