ABSTRACT:
A film mode detector detects film mode of a series of fields of video by comparing pixels in a field adjacent the current field, with corresponding pixels directly above and directly below the pixels in an adjacent field. The number of pixels in the adjacent in time to the current field having (or not having) a value approximately between values of the pixels above and below in the current field is assessed. Film mode for a current field may be detected by monitoring the assessment from field to field. Alternatively or additionally, the detector may detect film mode by assessing for each current field, whether a relatively large or relatively small number of pixels in the immediately previous field have values outside a specified distance of values of a corresponding pixel in the immediately subsequent field, for at least a portion of the immediately previous and subsequent fields. Again, film mode may be detected by monitoring this second assessment from field to field.
