Abstract
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 and which can respond to any of numerous highly accurate trigger signals for capturing a video image. Exemplary embodiments 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. Exemplary embodiments of the present invention relate to a method and apparatus for processing an input video data stream by receiving the input video data stream, and by automatically controlling processing of at least a portion of a video frame in response to a predetermined condition of the input video data stream.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
184 words
Method for processing an input video data stream comprising the steps of: receiving the input video data stream; and automatically controlling processing of at least a portion of a video frame in response to a predetermined condition of the input video data stream, said step of automatically controlling further including at least one of the steps of: controlling storage of said at least a portion of said video frame as a printable video image when a predetermined time interval has elapsed during receipt of said input video data stream; controlling storage of said at least a portion of said video frame as said printable video image by comparing at least portions of at least two frames of said input video data stream; comparing said at least a portion of said video frame to at least a portion of a pre-stored reference video frame to detect a match between said video frame and said reference video frame; and controlling storage of said at least a portion of said video frame as said printable video image upon detecting an audio signal associated with said video frame.
Claim 2
Dependent Claim
184 words
Method for processing an input video data stream comprising the steps of: receiving the input video data stream; and automatically controlling processing of at least a portion of a video frame in response to a predetermined condition of the input video data stream, said step of automatically controlling further including at least one of the steps of: controlling storage of said at least a portion of said video frame as a printable video image when a predetermined time interval has elapsed during receipt of said input video data stream; controlling storage of said at least a portion of said video frame as said printable video image by comparing at least portions of at least two frames of said input video data stream; comparing said at least a portion of said video frame to at least a portion of a pre-stored reference video frame to detect a match between said video frame and said reference video frame; and controlling storage of said at least a portion of said video frame as said printable video image upon detecting an audio signal associated with said video frame.
Claim 3
Dependent Claim
57 words
Method according to claim 1, wherein said step of automatically controlling further includes steps of: inputting a predetermined time code value; and controlling storage of said at least a portion of said video frame as said printable video image when a time code value associated with said input video data stream matches said predetermined time code value.
Claim 4
Dependent Claim
57 words
Method according to claim 1, wherein said step of automatically controlling further includes steps of: inputting a predetermined time code value; and controlling storage of said at least a portion of said video frame as said printable video image when a derived time code value from said input video data stream matches said predetermined time code value.
Claim 5
Dependent Claim
25 words
Method according to claim 3, further comprising a step of: reading said derived time code from a vertical synchronization interval of said video data stream.
Claim 6
Dependent Claim
20 words
Method according to claim 3, further comprising a step of: reading said derived time code from a longitudinal time code.
Claim 7
Dependent Claim
54 words
Method according to claim 1, wherein said step of comparing at least portions of at least two frames of said video data stream further includes a step of: detecting changes in characteristics of pixels included in a first of said at least two frames relative to a second of said at least two frames.
Claim 8
Dependent Claim
32 words
Method according to claim 6, wherein said step of automatically controlling further includes a step of: using said detected characteristic changes to indicate a scene change within said input video data stream.
Claim 9
Dependent Claim
46 words
Method according to claim 1, wherein said step of automatically controlling further includes a step of: receiving a general purpose interrupt; and controlling storage of said at least a portion of said video frame as said printable video image in response to said general purpose interrupt.
Claim 10
Dependent Claim
40 words
Method according to claim 1, further comprising a step of: controlling storage of said at least a portion of said video frame as said printable video image if a match exists between said video frame and said reference video frame.
Claim 11
Dependent Claim
49 words
Method according to claim 1, wherein said step of automatically controlling further includes steps of: examining said at least a portion of said video frame to detect a predetermined signal state; and storing said at least a portion of said video frame when said predetermined signal state is detected.
Claim 12
Dependent Claim
40 words
Method according to claim 1, further comprising a step of: receiving a control input; and controlling storage of said at least a portion of said video image when said predetermined condition exists and when said control input has been received.
Claim 13
Dependent Claim
24 words
Method according to claim 11, wherein said step of receiving further includes a step of: receiving a general purpose interrupt as said control input.
Claim 14
Dependent Claim
29 words
Method according to claim 1, further comprising a step of: controlling storage of said at least a portion of a video frame and information which identifies said predetermined condition.
Claim 15
Dependent Claim
144 words
Apparatus for processing an input video data stream comprising: a buffer for storing at least a portion of a video frame of an input video data stream as printable image data; and a processor for automatically controlling processing of said at least a portion of the video frame in response to a predetermined condition of the input video data stream, said predetermined condition corresponding to at least one of an elapsed predetermined time interval during receipt of said input video data stream, a comparison of at least portions of at least two frames of said video data stream, a comparison of at least a portion of said video frame to at least a portion of a pre-stored reference video frame to detect a match between said video frame and said reference video frame, and detection of an audio signal associated with said video frame.
Claim 16
Dependent Claim
144 words
Apparatus for processing an input video data stream comprising: a buffer for storing at least a portion of a video frame of an input video data stream as printable image data; and a processor for automatically controlling processing of said at least a portion of the video frame in response to a predetermined condition of the input video data stream, said predetermined condition corresponding to at least one of an elapsed predetermined time interval during receipt of said input video data stream, a comparison of at least portions of at least two frames of said video data stream, a comparison of at least a portion of said video frame to at least a portion of a pre-stored reference video frame to detect a match between said video frame and said reference video frame, and detection of an audio signal associated with said video frame.
