High quality multi-scan converter for XGA-LCD Projector by using Video DSP

Abstract

We developed a multi-scan converter for the LCD rear projector by using Video DSP "LAP" that can handle various video signals in real time by software. This system accepts standard TV format(NTSC, PAL, SECAM), computer display signals(VGA, SVGA, XGA, SXGA)and other non-standard formats by automatic scan adjust system. Using flexibility of Video DSP "LAP", we realize multi-function(such as selectable interpolation method and test signal generator), reducing man power and short TAT.
