Abstract

A digital image enhancer includes a deinterlacing processor receptive to an interlaced video stream. The deinterlacing processor includes a first deinterlacer and a second deinterlacer and provides a deinterlaced video stream. The digital image enhancer also includes a video output processor receptive to the output of the deinterlaced video stream to provide a scaled, deinterlaced video stream. A portable DVD player including the digital video enhancer has a generally thin prismatic enclosure having a first major surface, a second major surface separated from said first major surface, and side surfaces connecting the first major surface to the second major surface. At least a portion of the first major surface includes a video display, and the enclosure includes a DVD entry port such that a DVD can be inserted into the enclosure.

Dependent claims

A digital image enhancer comprising:

a video processor receptive to an interlaced video stream and providing a deinterlaced video stream comprising:
a first deinterlacer operative to analyze progressive frames of said interlaced video stream in an attempt to determine an original source type and sequencing used for the interlaced video stream and further operative to convert said interlaced video stream into a deinterlaced video stream using a conversion process that is dependent upon said detection of said original source type and sequencing;
and
a second deinterlacer operative to reduce motion artifacts detected by a frequency analysis of said interlaced video stream;
and
an output processor receptive to said deinterlaced video stream and operative to provide a scaled, deinterlaced video stream.
