Abstract:
1. A deinterlacing apparatus comprising: a mixing weight calculation unit to calculate a weight for mixing after detecting a degree of a motion between a pixel of a previous field and a pixel of a next field, which pixels correspond to a pixel of a current field to be interpolated; an intra-field interpolation unit to detect directional data included in values of pixels of the current field adjacent to the pixel to be interpolated into the current field, and to calculate a first interpolation value by using the values of the adjacent pixels in accordance with the directional data; an inter-field interpolation unit to calculate a second interpolation value obtained by averaging the values of the pixel in the previous field and the pixel in the next field corresponding to the pixel to be interpolated into the current field; and a soft switching unit to mix the first and second interpolation values by using the weight and to output a mixed value, wherein the mixing weight calculation unit comprises:
