Still Part Moving Part

The typical interlaced video frame includes both still and moving pixels. Sony Pixel-by-Pixel Active I/P conversion applies separate processing for each.

•Pixels for still objects are the easiest to handle. When objects are not moving, the player can simply use the corresponding pixel from the previous field. Because there is no motion, these pixels will match perfectly with the current field, creating a seamless progressive scan output.

STILL PIXEL PROCESSING

Pixels for still objects are simply created from the corresponding pixel in the previous field.

•Pixels for moving objects are created by composing pixels from scanning lines immediately above and below within the same field. Because all information comes from the same 1/60-second slice of time, this suppresses motion artifacts. While this process does not result in the full improvement in vertical resolution, the human eye is less sensitive to detail in moving objects. So the overall effect is a stunning improvement in image detail, clarity and solidity.
