Synchronisation eines Farbrades in einem Bildanzeigesystem |
摘要 |
<p>A motor control unit (15c) for synchronizing a color wheel (15) to an incoming video signal and for re-synchronizing the color wheel after a channel change. The motor control unit (15c) has an error control unit (31), which detects an out-of-phase condition, and derives a color wheel sync signal from the pixel sample clock adjusted by any phase error. A drive unit (33) phase locks this sync signal to an index signal provided by the color wheel. The result is a tightly controlled re-synchronization that minimizes perceived effects. <IMAGE></p> |
