| Summary: | The present invention relates to a method and/or architecture for implementing a video field freeze filter generally and, more particularly, to generating a new frame from only one of two interlaced fields in an original frame.
A circuit for freezing a video frame having a first field interlaced with a second field. The circuit generally comprises a memory and a filter. The memory may be configured to present a plurality of coefficient signals that define (i) a first coefficient set for the first field and (ii) a second coefficient set for the second field. The filter may be configured to present a new frame in place of the video frame. The new frame may be generated from either (i) the first field and the first coefficient set in response to freezing on the first field or (ii) the second field and the second coefficient set in response to freezing on the second field. |
