Abstract

The present invention is directed to reversing the trend in conventional video printing by providing a cost-effective, flexible device which is independent of the printing device such that it can be used with any conventional computer printing device to provide plain paper prints of video images. By focusing on optimizing cost-effectiveness and system flexibility rather than providing high resolution photographic quality prints, the present invention can provide video printing features never before realized. Generally speaking, the present invention relates to a method and apparatus for processing an input video data stream by selecting at least a portion of a frame of the input video data stream as printable image data, and by processing the selected a frame to correlate the frame to said input video data stream using at least one identifier. Further, the present invention relates to a method and apparatus for processing an input video data stream by storing at least a portion of a frame of the input video data stream as printable image data, and by processing the printable image data to automatically reposition the frame on a printable medium.

Claims

printing said at least one of said selected plural frames in said reordered print sequence in accordance with a print format.

2. Method according to claim 1, further comprising a step of:

controlling storage of said at least one identifier as printable image data.

3. Method according to claim 2, further comprising a step of:

printing said at least one of said selected portions of the frames and said identifier.

4. Method according to claim 3, wherein said step of storing at least one identifier further includes a step of:

storing said at least one identifier in response to a control input.

5. Method according to claim 1, further comprising a step of:

storing said index as a bar code representation.

6. Method according to claim 1, wherein said step of processing further includes a step of:

storing an indicator of a video effect associated with said at least one of said selected portions of the frames.

7. Method according to claim 6, further comprising a step of:

controlling storage of said indicator as a textual or iconic reference; and

printing said at least one of said selected portions of the frames and said textual or iconic reference.

8. Method according to claim 6, further comprising a step of:

controlling storage of an indicator of an audio effect associated with said at least one of said selected portions of the frames.

9. Method according to claim 1, wherein said step of processing further comprises a step of:

automatically positioning said at least one of said selected portions of the frames and said at least one identifier on said printable medium.

10. Method according to claim 9, further comprising a step of:

automatically detecting that said at least one of said selected portions will not fit on an available printable medium; and

processing said printable image data to automatically rotate said at least one of said selected portions relative to said printable medium upon automatically detecting that said at least one of said selected portions will not fit on said available printable medium.

12. Apparatus for processing an input video data stream comprising:

a buffer for storing at least portions of plural frames of an input video data stream as printable image data; and

a processor for processing said at least portions of the plural frames stored in said buffer to correlate said at least portions of the frames to said input video data stream using at least one identifier, wherein said identifier includes an index which correlates at least one of said selected portions of said frames to a sequential location within said incoming video data stream and an image sequence identifier which identifies a reordered print sequence within which said stored portions of said video frames are to be printed, said identifier being stored with said at least one of said selected portions of the frames for retrieving said at least one of said portions of said frames from said memory, said processor controlling printing of said at least one of said selected plural frames in said reordered print sequence in accordance with a print format.

13. Apparatus according to claim 12, further comprising:

a converter for converting said at least one of said selected portions of said video frames from a first video data format to a second video data format; and

a data compressor for selectively reducing an amount of stored data used to represent said at least a portion of the frame in said buffer.

14. Apparatus according to claim 12, wherein said processor further includes:

means for selectively trimming said at least one of said selected portions of the frames stored in said buffer;

means for scaling a printable image associated with said printable image data of said at least one of said selected portions of the frames; and

means for formatting said printable image data of said at least one of said selected portions of the frames and said identifier for output to a printing device.

15. Apparatus according to claim 14, wherein said processor further includes:

means for correcting color of said printable image.

17. Apparatus according to claim 12, wherein said processor automatically detects that said at least of said selected portions will not fit on an available printable medium, and processes said printable image data to automatically rotate said at least one of said selected portions relative to said printable medium upon automatically detecting that said at least one of said selected portions will not fit on said available printable medium.
