SXGA/HDTV ADVANCED IMAGE PROCESSOR
sxW1
Silicon Optix sxW1 highly integrated image processor that enables convergence digital image processing optics. sxW1 incorporates geometry correction, advanced scaling, frame rate conversion, de-interlacing picture-in-picture circuitry into single component provide cost effective solution advanced applications capture, display transmission digital visual information. Silicon Optix sxW1 corrects keystone, pincushion, tilt, barrel aspect ratio distortions using advanced image processing techniques. This electronic correction feature decreases cost weight sophisticated camera projection systems simplifying optics. Silicon Optix sxW1 provides flexible electronic solution that correct severe geometry optical distortions. correction parameterized array coefficients that user programmable updated each frame dynamic geometry processing. advanced scaling engine allows smooth continuous zooms shrinks, free from scaling artifacts. dynamically allocating filters, Silicon Optix sxW1 provides high quality image shrinks, reducing data rates prior compression transmission over broadband wireless transmission systems. Silicon Optix sxW1 supports full range industry standard graphics video input output formats ensure compatibility. Video inputs processed spatial mesh de-interlacing techniques ensure optimal image quality when displayed progressive mode. Frame rate conversion broadens range supported formats allowing independent input output frame rates. addition, secondary input channel used capture external source picture picture overlays. high level integration Silicon Optix sxW1 substantially reduces number external components required system solution leading more compact, more reliable, lower cost products.
