Abstract
Methods of processing pixel data for display on a spatial light modulator (SLM) (15) having staggered pixels. An analog image signal in interlaced field format is sampled to provide staggered pixel data in field format, where pixel values in odd lines are offset from pixel values in even lines. This staggered pixel data may be converted to progressive scan frame format using special calculations to accommodate the line-to-line offset of the pixels (FIGS. 2-6). Vertical scaling may also be performed, either before or after the data is converted to frame format (FIGS. 7 and 8).
