Abstract
The present disclosure relates to a video recording method and a video recording apparatus using the same, and relates to a video recording method and a video recording apparatus using the same that detects an obstacle in scene information obtained, calculates a probability index for event occurrence (i.e., a collision) with the obstacle, and changes and stores a resolution of a video, a storing period, a storing location, and so on based on the probability for event occurrence.
Claims10
A video recording method of a video recording apparatus, comprising:
- (A) obtaining scene image;
- (B) analyzing the obtained scene image and calculating a probability index for collision occurrence;
- and
- (C) when it comes to storing the scene information obtained via the obtaining scene and the analyzing the calculated probability index for collision occurrence,
- changing at least one selected from a resolution of a video and a storing interval and storing the scene information;
- wherein the changing comprises starting video recording, and increasing the resolution of video and decreasing the storing interval as the calculated probability index for collision event occurrence is higher.

A video recording apparatus, comprising:
- a camera that obtains scene image;
- a calculator for calculating a probability index for collision occurrence that analyzes the scene image obtained by the camera and calculates a probability index for collision occurrence;
- a recorder that stores the scene image obtained by the camera;
- at least one of a distance to the detected obstacle from the event recording apparatus, a relative velocity of the obstacle with respect to the video recording apparatus, a relative acceleration of the obstacle with respect to the video recording apparatus, and a Time-to-Collision (TTC), and
- a controller for recording that changes at least one selected from a resolution and a storing interval of a video in the recorder based on the probability index for collision occurrence calculated by the unit for calculating a probability index for event occurrence;
- wherein the controller for recording starts the video recording and increases the resolution of the video and decreases the storing interval as the calculated probability index for collision occurrence is higher.
