In general, a device for recording the situation of the accident that can occur during the operation of the vehicle has been continuously developed. Images acquired by an image acquisition device such as a camera (analog or digital camera), a camcorder, or the like installed in a vehicle are stored in a storage device such as a film, a tape, or a memory. If a special situation does not occur due to the limitation of the capacity of the storage device, the image is stored by overwriting after a certain time.

However, it is difficult to accurately determine the situation of an accident with only image information. For example, if one vehicle suddenly stops due to a special situation while driving, but the other vehicle collides behind the vehicle, it is difficult to identify the root cause of the collision by the video information alone. In this case, there may be a method of detecting the speed of the vehicle together using the vehicle speed sensor installed on the drive shaft of the wheel of the vehicle. However, this method also makes it difficult to make accurate situation determination when the vehicle moves in a situation where the wheels of the vehicle do not rotate.

The recording controller 120 acquires an image from the image acquisition unit 110 mounted at a predetermined position of the vehicle, and when the shock is detected from the outside or when the user stops recording, The memory 160 stores the first moving speed, the second moving speed, and the current time. In addition, the recording controller 120 stores the image in an overwrite manner when there is no impact from the outside or when there is no request to stop recording from the user.

The sensor unit 130 is installed on a shock sensor 131 for detecting a shock from the outside, and a drive shaft (not shown) of the wheel of the vehicle, the vehicle for detecting the first moving speed according to the rotation of the wheel of the vehicle And a speed sensor 132.

The display 140 displays an image acquired from the image acquisition unit 110. The key input unit 150 includes keys (not shown) for adjusting a recording screen of an image displayed on the display unit 140 and setting a recording time. Although the display unit 140 and the key input unit 150 have been described as separate devices, the display unit 140 and the key input unit 150 may be configured in the form of a touch panel in which the display unit 140 and the key input unit 150 are integrated.

The GPS receiver 170 receives a second movement speed and a current time according to the actual movement of the vehicle from the GPS. The GPS receiver 170 may be any one of a GPS receiver, a GPS navigator, and a GPS vehicle computer.

The memory 160 stores an image including the first moving speed, the second moving speed, and the current time.

In the memory 160, an image is repeatedly stored in a predetermined section for a predetermined time for efficient use of a storage location, and this method will be described in detail with reference to FIG. 2.

Second Embodiment

A second embodiment of the present invention is a video recording apparatus including a GPS receiver integrated recording unit 100b, which is the same as the components of the first embodiment, but without using an existing GPS receiver, a GPS navigator, or a GPS vehicle computer. It differs from the first embodiment in that an integrated recording device including a GPS receiver 170 is used. The operation of the components of the second embodiment is the same as the operation of the components of the first embodiment.

2 is a flowchart illustrating a video recording method of a vehicle according to the present invention, which will be described with reference to the components of FIG. 1.

Referring to FIGS. 1 and 2, first, a user checks an image displayed on the display unit 140, adjusts an angle, brightness, magnification, etc. of a recording screen and sets a recording time through the key input unit 150. (Step S200). Here, the recording time refers to a time for recording in a circular manner in order to overwrite the memory 160, for example, recording any one of the recording time, such as 3 minutes cyclic recording, 5 minutes cyclic recording, 10 minutes cyclic recording, etc. The time may be set by the user through the key input unit 150. In addition, when setting the recording time, the first time t ₁ and the second time t ₂ described later can be set.

When the user commands the start of recording through the key input unit 150, the recording controller 120 starts to record the image obtained from the image acquisition unit 110 (step S205).

The recording controller 120 determines whether an impact from the outside is detected by the impact sensor 132 (step S210). If the shock is detected, recording is stopped after the recording is continued for the first time t ₁ seconds (step S215). Here, the first time t ₁ may be, for example, 20 seconds and may vary depending on a setting. If the shock is not detected, it is determined whether or not to stop recording from the user (step S220). If it is requested to stop recording from the user, the flow proceeds to step S215. If it is not requested to stop recording, the flow proceeds to step S225.

It is determined whether partial storage is requested from the user (step S225). If the partial storage is requested, image information from the second time t ₂ seconds before the request time to the current time is separately stored (step S230). Here, the second time t ₂ may be, for example, 30 seconds, and may vary depending on a setting. At step S225, the partial storage is not requested or after step S230, it is determined whether it is the last point of the circular storage space of the memory 160 at the present time (step S235). If it is not the last point of the circular storage space, the flow proceeds to step S210. If it is the last point of the circular storage space, the recording is continued by overwriting, that is, changing the recording information to the address of the storage space at the first recording time (S240).

The invention can also be embodied as computer readable code on a computer readable recording medium. The computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, flash memory, and the like, and also in the form of carrier waves (for example, transmission over the Internet). It includes what is implemented. The computer readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. And functional programs, codes and code segments for implementing the present invention can be easily inferred by programmers in the art to which the present invention belongs.

Although a preferred embodiment of the present invention has been described in detail above, those skilled in the art to which the present invention pertains can make various changes without departing from the spirit and scope of the invention as defined in the appended claims. It will be appreciated that modifications or variations may be made. Accordingly, modifications to future embodiments of the present invention will not depart from the technology of the present invention.
