Patent ID: 8774278

Claim:
A motion detector for detecting motion in an interlaced video signal, the motion detector comprising: a frame motion detector receiving a first field of the interlaced video signal and a second field of the interlaced video signal, the first field being different from the second field and having a same parity as the second field, the frame motion detector being configured to determine a first motion value based on the first field and the second field by using a first window having a first size, to determine a second motion value based on the first field and the second field by using a second window having a second size, the second size being different from the first size, and to selectively blend the first motion value and the second motion value to generate a frame motion value corresponding to a missing pixel of a current field of the interlaced video signal; a field motion detector receiving the current field and a third field of the interlaced video signal, the third field having an opposite parity to the current field, the field motion detector being configured to generate a field motion value corresponding to the missing pixel based on the current field and the third field; and a weaver/interpolator to receive a blend factor corresponding to the missing pixel that is based upon the frame motion value and the field motion value and generate a pixel value for the missing pixel based upon the blend factor, the pixel value being one of a weaved pixel value, an interpolated pixel value, and a blend of the weaved pixel value and the interpolated pixel value.
