Abstract
A method and system for interpolating a missing pixel in a current field of an interlaced video format signal. The method includes performing a low-pass estimate in the current field about the missing pixel. A high-pass estimate is also performed in a temporally local field to the current field. The high-pass estimate is performed in the temporally local field at a position connected to the missing pixel by a motion vector. The value of the missing pixel is then determined by combining the high pass estimate with the low-pass estimate performed in the current field.
