DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The file stored in the memory card of the black box is very large in the size of a file encoded with a high resolution image. Therefore, when a black box for a vehicle is normally recorded, a moving picture file is generated every minute, so writing to a memory card (or a storage medium) such as an SD card frequently occurs. In addition, since the video stored in the black box is judged to be an important event in itself, the memory may be frequently written to the memory card due to an event having a high positive error rate, which is not important to the user.

Here, an event may include an impact or a collision situation, an overspeed situation, a sudden deceleration situation, a rapid acceleration situation, an external noise change, and the like.

In this way, when moving picture files of a relatively large capacity are frequently written to the memory card, the storage space of the memory card is insufficient due to the capacity limitation of the memory card, and when a new moving picture file is stored, (Or overwriting) is required. As a result, the deleted image file can not give any information to the user any more, so that the user may experience inconvenience of lack of information.

Accordingly, in order to maximize the lifetime of the information about the image stored in the memory card, the black box system according to the present invention simultaneously generates a single image or image (representative image) file when generating a moving image file, And a single image file or a low capacity image file can be stored in a memory card as a storage medium.

1 is a block diagram showing the configuration of a video accident recording apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the video accident recording apparatus may include a video photographing apparatus 110, a controller 120, a memory card 130, a DRAM 140, and a sensor 150.

The image photographing apparatus 110 can photograph an image and provide it as a file. Here, the image photographing apparatus 110 is generally a camera, and a vehicle front camera, a rear camera, a side camera, or the like can be applied. It is also possible to provide an audio file recorded through a microphone or the like.

The control unit 120 may store a file provided by the image photographing apparatus 110 according to an event sensed by the sensor 150, and may determine the importance of the file and generate storage or overwriting. The control unit 120 may check the empty space in the memory card 130 and may store a new file in the memory card 130 when an empty space is confirmed. If a vacant space is not found in the memory card 130, the memory card 130 may be searched for a file with the lowest importance, and the file having the lowest importance may be replaced with a new file to be overwritten and stored in the memory card 130 .

Generally, the importance of the file is determined according to the generation time of the file. In order to maintain the file for a long period of time, Can be determined.

The memory card 130 may store a file provided by the controller 120. [ The memory card 130 is made up of a nonvolatile memory and stores metadata including video and audio files and other information (file creation time, file storage location, file name, file importance, etc.) It is a storage means that can be stored. Herein, the memory card 130 includes a storage medium that is built in or external to a vehicle black box for storing data, and examples of the storage medium include an SD card (Secure Digital Card), a Micro Secure Digital Card ), A flash memory, a solid state drive (SSD), a hard disk drive (HDD), and a USB memory (Universal Serial Bus). In addition, various kinds of digital storage Media is available.

Unlike the memory card 130, the DRAM 140 may be a temporary storage unit that is made up of a volatile memory and deletes stored contents when power supply is interrupted. As described above, the use of the volatile memory can temporarily improve the processing speed and the like by temporarily storing information in another apparatus to facilitate transmission and reception of information.

Finally, the sensor 150 may sense the event by at least one or more sensors. Here, the type of the sensor 150 is not limited, but a collision detection sensor, a speed detection sensor, an acceleration sensor and a rotation detection sensor, a laser, an ultrasonic wave, a GPS, a sound sensor, There will be. Accordingly, it is possible to detect the peak change rate information of the acceleration sensor value, the GPS (Global Positioning System) position information, the information by the motion sensor, the moving speed of the vehicle, the user's intention, And information on the size of the object.

2 is a flowchart illustrating a method of storing a representative image of a video accident recording apparatus according to an exemplary embodiment of the present invention.

In the following, a specific process will be described as an example of the image file among the files recorded in the driving and parking of the vehicle.

Referring to FIG. 2, a method of storing a representative image of a video accident recording apparatus includes the steps of generating, in step 210, a video file to store a video image captured by a video photographing apparatus such as a camera on a storage medium, can do. Here, the size of a file encoded with a high-resolution image is very large.

When storing the moving image file in step 220, the image incident recording apparatus may generate a representative image file having a small capacity and a small capacity using the moving image file. At this time, the representative image file can be generated for at least a part or all of the moving image file. Preferably, the representative image file includes at least an image at the time when the event occurs.

Here, the representative image file may be generated by lowering the resolution of the moving image file.

In addition, when generating the representative image file, a low-capacity representative image file can be generated by deleting a part of the frame of the moving image file. That is, the representative image file can cut out a part of a frame constituting an image and generate an image file composed of the remaining frames.

In addition, when generating the representative image file, a representative image file may be generated using an image of one frame among the frames of the moving image file. At this time, the representative image file may have one or more images. Since the representative image file has a much smaller capacity than a moving image file, it can be stored in a black box storage medium for a long period of time.

For example, the FAT32 file system is widely used for compatibility of files stored in black box systems and limits the maximum storage capacity to 32GB.

Therefore, the maximum capacity of the SD card memory driven by the FAT32 file system is limited to 32 GB.

The file stored in the SD card of the black box is a moving image file, and has a large capacity of 1 MB per second based on the super high definition image (Full HD). When a black box of a vehicle is always recorded, a video file is generated every minute, so writing to the SD card frequently occurs, and the old image may be deleted according to the limited capacity of the SD card.

Later, when an emergency situation occurs and a user wants to find information about a file very long ago, the user can not obtain any information in the conventional black box.

According to the present invention, when generating a moving image file, a single representative image file can be simultaneously generated, and a moving image file and a single representative image file can be stored in the SD card.

Then, on the basis of the Full HD image, a single image file is about 200 KB, and when stored in a 0.5 GB backup area, about 2,600 representative image files can be stored. Therefore, even if the user is an old file, the user can acquire minimum information of the representative image.

In step 230, the video accident recording apparatus may store the moving image file and the representative image file in a storage medium in a black box such as a memory card. At this time, it is preferable that the storage medium is divided into a plurality of storage areas. Accordingly, the moving picture file and the representative picture file can be stored in the corresponding storage area of the storage area of the storage medium.

If the moving picture file is deleted in step 240, the video accident recording apparatus may store the representative picture file of the moving picture file to be deleted in the backup storage of the storage medium.

That is, when the video file is deleted and overwritten, the video accident recording apparatus stores the representative video file in the backup storage of the storage medium.

Here, information of the storage area in which the moving picture file to be deleted is stored may be stored in the backup storage of the storage medium together with the representative image file. Accordingly, the representative image file stored in the backup storage can know the location of the storage area where the original moving image file was stored, thereby confirming the event detected in a certain situation. It is also possible to store the event occurrence time together with the representative image file.

For example, a moving picture file stored as an event due to a parking impact may be stored in the parking impact storage area of the storage medium. At this time, the representative image (image) file of the moving image file can be stored together. After the time elapses, when the moving image file is overwritten, the representative image file is stored in the backup storage of the storage medium. In addition, the backup storage may store the information about the parking impact storage area and the time of occurrence of the event together with the representative image file.

Here, a concrete procedure of the image file among the files recorded at the time of vehicle operation and parking has been described. However, a sound file recorded through a microphone or the like can also be created as a separate representative sound file and stored in the backup storage.

3 is a structural view illustrating a storage medium of a video accident recording apparatus according to an embodiment of the present invention.

Referring to FIG. 3, the storage area of the storage medium is divided into a plurality of storage areas including a back-up storage area.

Accordingly, when the moving image file is overwritten and deleted from another file, the image accident recording apparatus can store the representative image file or the representative image file associated with the moving image file in a separate backup storage.

The video accident recording apparatus may store the information of the storage area in which the moving picture file to be deleted is stored, together with the representative picture file, in the backup storage of the storage medium. Accordingly, the representative image file stored in the backup storage can know the location of the storage area where the original moving image file was stored, thereby confirming the event detected in a certain situation. It is also possible to store the event occurrence time together with the representative image file.

For example, a memory card, which is a storage medium, is divided into a normal recording area, an impact area, a parking motion area, a parking impact area, a manual recording area, and a backup storage, The size of the space can be assigned. In addition, the size of each space of the memory card can be flexibly adjusted as needed. At this time, by setting the fixed size of the backup storage to be allocated, important files can be prevented from being deleted regardless of the intention of the user.

When the moving picture file stored in the storage area is deleted or overwritten, the corresponding image file can be stored in the backup storage. At this time, the storage area information and the time information of the original of the image file can be stored together.

4 is a diagram illustrating an example of storing an image according to an event according to an embodiment of the present invention.

Referring to FIG. 4, the video-accident recording apparatus records, stores, and deletes video in a normal recording state. When an event such as an impact detection or a motion detection occurs, an image before and after an event can be stored. For example, 10 seconds before an event, 10 seconds after an event, and 20 seconds in total can be saved as a video file. At this time, the recording time stored in the moving picture file can be changed.

Accordingly, when the occurrence of an event is detected, the video accident recording apparatus stores a moving picture file, and a representative picture (image) file can be stored. Here, the representative image file may be a moving image file, an image file, an audio file, or the like, and preferably includes at least an image (or voice) at the time of occurrence of an event.

5 is a diagram illustrating an example of a method of storing a representative image file according to an exemplary embodiment of the present invention.

Referring to FIG. 5, when storing a moving image file, the image incident recording apparatus may generate a representative image file having a small capacity and a small capacity using the moving image file. That is, the representative image file can be saved by minimizing the capacity of the storage file by reducing the image quality, resolution (frame size) of the moving image file, or fps, which is the number of frames per second.

Accordingly, the representative image file can be generated by lowering the image quality or resolution of the moving image file.

In addition, when generating the representative image file, a low-capacity representative image file can be generated by deleting a part of the frame of the moving image file. That is, the representative image file can cut out a part of a frame constituting an image and generate an image file composed of the remaining frames.

In addition, when generating the representative image file, a representative image file may be generated using an image of one frame among the frames of the moving image file.

Therefore, the limited storage capacity can be used more efficiently.

6 is a diagram illustrating an example of storing representative images of a video-accident recording apparatus according to an embodiment of the present invention.

6, when there are a plurality of moving image files on the storage medium, and the moving image file is deleted or overwritten, the image accident recording apparatus records the representative image of the moving image file to be deleted in the backup storage of the storage medium By storing the file, the representative image file can be stored for a long period of time.

Here, the representative image file may be stored in the back-up storage of the storage medium together with the information of the storage area in which the original moving image file to be deleted is stored, so that information of the event that has occurred through the representative image file can be confirmed later.

7 is a block diagram illustrating a system for storing representative images of a video-accident recording apparatus according to an embodiment of the present invention.

Referring to FIG. 7, the file generation unit 310 may generate a moving image file photographed by the image photographing apparatus. It is possible to generate a moving picture file for storing an image photographed by a video photographing apparatus such as a camera in a storage medium. Here, the size of a file encoded with a high-resolution image of the moving image file is very large.

The representative image generating unit 320 may generate a representative image file having a small capacity and a small capacity using the moving image file generated by the file generating unit 310. [ At this time, the representative image file can be generated for at least a part or all of the moving image file. In addition, the representative image file preferably includes an image at a time when the event occurs.

Accordingly, the representative image generating unit 320 may generate a low-resolution representative image file by lowering the resolution of the moving image file.

When generating the representative image file in the file generation unit 310, the representative image generation unit 320 may generate a low-capacity representative image file by deleting a frame part of the moving image file. That is, the representative image file is a video file composed of a remaining frame and a part of a frame constituting the video, and occupies a very small portion in the storage space. At this time, it is preferable that the representative image file includes at least an image at the time when the event occurs.

In addition, the representative image generator 320 may generate a representative image file using an image of one of the frames of the moving image file. At this time, the image of the representative image file may be one or more than one. Since the representative image file has a much smaller capacity than a moving image file, it can be stored in a black box storage medium for a long period of time. Here, it is preferable that the representative image file includes at least an image at the time when the event occurs.

The storage unit 330 may store the moving image file and the representative image file generated by the file generation unit 310 and the representative image generation unit 320 in a storage medium.

The storage unit 330 separately stores the representative image file of the moving image file deleted and overwritten in the backup storage of the storage medium when the moving image file is deleted and overwritten, Video and images) can be stored for a long period of time.

Accordingly, it is preferable that the storage medium is divided into a plurality of storage areas, and the moving picture file and the representative image file are stored in one of the storage areas. The storage unit may store information of the storage area in which the moving picture file to be deleted is stored, together with the representative image file, in the backup storage of the storage medium.

According to the present invention, in order to maximize the lifetime of information about images stored in the memory card, a single image file (representative image file) is generated simultaneously when a moving image file is generated, Can be stored on card.

Accordingly, when a moving image is overwritten and deleted from another file, an image image (representative image) file associated with the overwritten moving image file can be stored in a separate backup area.

In addition, it is also possible to determine the importance by the black box system and to generate a representative image (image) file only for the video file that is deemed important, and to store the representative video file with high importance immediately in the backup storage It is also possible.
