AUTO-TRIGGERED FAST FRAME RATE DIGITAL VIDEO RECORDING
First Claim
1. A video recording method comprising:
- buffering digital video data captured by a video sensor in a video data buffer;
detecting motion or a scene change in the buffered digital video data;
recording at least a portion of the buffered digital video data in a data storage device in response to the detection of motion or a scene change; and
recording digital video data newly captured from the video sensor in the data storage device in response to the detection of motion or a scene change.

Abstract
This disclosure describes techniques for triggering recording of digital video in a fast frame rate mode. In one example, a digital video recording apparatus includes a video sensor that captures digital video data at a fast frame rate in a fast frame rate mode, a video buffer that buffers the captured digital video data according to a first-in-first-out storage schema, a video storage that stores digital video data, and a motion detection unit that detects fast motion in the buffered digital video data, that stores digital video data from the video sensor in the video storage after detecting the fast motion, and that copies the contents of the video buffer to the video storage prepended to the stored video data. The digital video recording apparatus may be incorporated in a wireless communication device, such as a cellular phone.
