Abstract:
1. Method for recording an event initiated video sequence, the method comprising: continuously capturing video frames; temporarily storing video frames in a video buffer; detecting a first event; initiating, in response to the detection of the first event, a video sequence recording session for recording of a video sequence in a non-volatile memory; recording, in response to the detection of the first event, in the non-volatile memory, pre-event frames of the captured video data present in the buffer; recording, in the non-volatile memory, post-event frames of the video data captured during a post-event time period related to the first event, the post-event time period starting at the detection of the first event; starting a first event delay time period in response to the expiration of the post-event time period of the first event; detecting a second event after expiration of the post-event time period of the first event and before expiration of the first event delay time period; recording, in response to detection of the second event, in the non-volatile memory, frames from the video buffer representing a time period starting at the expiration of the post-event time period of the first event and ending at the detection of the second event; recording, in the non-volatile memory, frames of the video data captured during a post-event time period related to the second event, the post-event time period starting at the detection of the second event; and closing the video sequence recording session if a delay period expires and no other event process is in progress, wherein an event process includes recording pre-event frames, recording post-event frames, and an event delay time period, and wherein the delay period is a period counted from the expiration of a post-event time period.
