Abstract:
1. An adaptive deflicker method for use in converting a non-interlacing scan data into an interlacing scan data, comprising the steps of: receiving a non-interlacing scan data including plural scan lines; comparing a color space value of a first pixel of a selected one of said scan lines with that of a second pixel of another scan line immediately adjacent to said selected scan line at a position corresponding to said first pixel, and determining said first pixel to be an edge point when the norm of a color space value difference of said first and second pixels is larger than a preset value; repeating locating edge points and defining an edge line including a plurality of consecutive edge points; performing a deflicker operation on a selected part of said edge line; exempting a non-edge line of said non-interlacing scan data from said deflicker operation; and converting said non-interlacing scan data into an interlacing scan data.
