Description

METHOD AND SYSTEM FOR RECORDING IMAGE USING PORTABLE BLACKBOX OF NON-RECORD}

The present invention relates to a video recording system and method using a non-recording portable black box.

As society has become more complex, various incidents, accidents, and violent crimes have also occurred frequently, and there is a growing fear of being exposed to unexpected crime situations, regardless of gender. In this case, an individual may carry a self-defense device for voluntary response in the event of a sudden event or accident, but in such a case, it is difficult to seek help from others, and if a person is in danger, he is embarrassed and does not use the self-defense device properly. There is a disadvantage that can not.

Therefore, when an individual is exposed to an emergency situation, prompt reporting or request for external help is required. In the related art, a mobile phone with a function to designate a shortcut key or a terminal dedicated to reporting an emergency situation has been used.

This is to allow the user to connect to a pre-specified acquaintance or promptly report to a police station when a user presses a certain button or the like in case of an emergency. However, since such devices must be accompanied by an individual's conscious pressing of the button, there is a problem that the button is rendered useless when the act of pressing the button is impossible, such as when exposed to a crime or an emergency.

Accordingly, recently, a method for automatically determining an emergency using a pulse wave and acceleration of the human body has been developed, such as an emergency pager that detects and judges an emergency situation of a user wearing a device by a sensor. However, this method has a problem in that it is difficult to accurately grasp the situation, and there is a limit to prompt response, and there is a problem in that the victim has to undergo a painful investigation process because there is no evidence left afterwards.
