Method and system for quantized historical motion for motion detection in motion adaptive deinterlacer

摘要

In a video system, a method and system for quantized historical motion for motion detection in a motion adaptive deinterlacer are provided. A motion-adapted value for an output pixel in a current output field may be determined based on a current motion value and a historical motion value. The current motion value may be based on a pixel constellation and may be quantized once determined. The quantized current motion value may be stored and may be used to determine a quantized historical motion value for an output pixel in a field occurring after the current field. At least one quantized historical current motion value may be used to determine the quantized historical motion value for the output pixel in the current output field. The quantized historical motion value may be reverse quantized to determine the historical motion value for the output pixel.
