Abstract:
1. A deinterlacing apparatus, comprising: a buffer unit having a previous field buffer, a current field buffer, and a next field buffer to store, sequentially, individual fields of an image signal which are successively inputted; a zero motion estimation unit to calculate a Sum of Absolute Difference (SAD) value by a predetermined search region unit with reference to a next field stored in the next field buffer and a previous field stored in the previous field buffer; a still region/film mode detection unit to determine whether the predetermined search region is a still region and whether a source of the image signal is a film based on the SAD value; a 3D interpolation unit to output adaptively a temporal interpolation value and a spatial interpolation value based on motion information; and an adaptive selection unit to output a deinterlacing result based on the previous field, the next field, and an output of the 3D interpolation unit according to a signal outputted from the still region/film mode detection unit.
