Abstract:
1. A motion-compensation adaptive deinterlacing apparatus, comprising: a still image detection unit to detect whether an input image is a still image; a motion estimation unit to estimate motion information of a pixel to be interpolated of the input image when the input image is not a still image, the motion estimation unit having: a pixel insertion unit to interpolate the pixel to be interpolated using pixels in previous and next fields with respect to a reference field including the pixel to be interpolated when the input image is the still image; a motion compensation unit to interpolate the pixel to be interpolated using motion information estimated by the motion estimation unit when the input image is not the still image and has no vertical fast motion; a spatial interpolation unit to interpolate the pixel to be interpolated using pixels of the reference field including the pixel to be interpolated when the input image has the vertical fast motion; and a switching unit to activate one of the pixel insertion unit, the motion compensation unit, and the spatial interpolation unit according to results from the still image detection unit and the motion estimation unit.
