Description

Technical Field [0001] The present invention relates to a black box device for a vehicle,

The present invention relates to a black box apparatus and a control method thereof. More particularly, the present invention relates to a black box apparatus and a control method thereof for recording an event image And a control method of the black box device for a vehicle, which can generate a regularly recorded video file having a constant size at all times.

In general, the black box is well known for its use and its role, but its internal structure and operating principle refer to the hidden device, usually the aircraft state (altitude, route, speed, engine condition, etc.) It is a device developed for the purpose of accurately detecting the accident situation of the aircraft by analyzing the contents of the black box when an accident occurs in the aircraft.

Recently, a black box for automobiles has been developed, and images of the front, side, or rear of the vehicle are captured and recorded as moving images, and the images of the black box are analyzed when a traffic accident occurs.

Due to this necessity, the development of a black box for a vehicle is actively progressing in the domestic market.

The black box has a camera and a microphone installed inside and outside the terminal for storing video and audio of the inside or outside of the vehicle, and is capable of recording only the "normal recording" Quot; impact recording "and the like.

In this case, the continuous recording is a method of performing continuous recording while the vehicle is running, and the continuous recording is performed by storing the continuous recording at a predetermined time (for example, 1 minute) or a file size (for example, 100 MB) (10 seconds before the impact occurrence time to 10 seconds after the shock occurrence time) (for example, a time interval of 10 seconds after the impact occurrence time) when the impact is detected through the detection sensor (e.g., G sensor) , An impact image or an event image) is stored in another folder in the memory card.

Therefore, when the impact recording is performed during the normal recording, the user can see the normal recording image as if the normal recording image is lost (i.e., not recorded) by the impact recording interval (time) (see FIG.

For example, as shown in FIG. 1, if it is assumed that the normally recorded image is intermittently stored in units of one minute, when the impact occurs more than a certain amount of time during normal recording (event occurs) The user can mistakenly think that the normal recording image is not recorded.

In addition, there is a problem that a file fragmentation phenomenon may occur because a normally recorded image file is finely divided and stored by a frequent impact (event) in a situation in which an impact (event) frequently occurs (for example, a road running state on an irregular road surface) .

Here, the file fragmentation phenomenon refers to a phenomenon that the empty space of the storage device (e.g., a removable memory card) or the data is divided into a plurality of pieces. Such a fragmentation phenomenon may reduce the usable space of the storage device, . ≪ / RTI >

In particular, the vehicle black box must record a predetermined amount of image in a predetermined time within a predetermined time. If the access speed is lowered as described above, a memory overflow occurs and the system (i.e., a vehicle black box) Causing a serious problem such as down or system reset.

If a serious problem occurs in a system (i.e., a black box for a vehicle) due to a fragmentation phenomenon occurring in a removable disk used as a storage device in a vehicle black box, the user backs up the image stored on the removable disk, It is inconvenient to solve the fragmentation problem.

Therefore, definitions of these terms should be made based on the contents throughout this specification.

FIG. 2 is an exemplary view showing a schematic configuration of a black box device for a vehicle according to an embodiment of the present invention.

2, the vehicle black box device according to the present embodiment includes a camera unit 110, an audio unit 120, a guide image generation unit 130, a first video encoder unit 140, A first video encoder unit 160, a control unit 170, an impact sensor unit 180, and a storage unit 190.

The camera unit 110 photographs images of the surroundings of the vehicle in real time.

The camera unit 110 may include at least one camera (e.g., a first camera and a second camera).

The first video encoder unit 140 encodes an image captured by the camera unit 110 and outputs the encoded image to the controller 170.

The audio unit 120 acquires the ambient sound (sound) of the vehicle black box device (hereinafter, referred to as a black box) in real time.

The audio encoder unit 150 encodes the sound (sound) acquired from the audio unit 120 and outputs the encoded sound to the controller 170.

The guide image generating unit 130 inserts the still image into the disconnected section of the normally recorded image when the normally recorded image is disconnected by the event (shock) image recording during the image recording of the black box according to the present embodiment, ) To generate a guide image guiding that it is a break interval due to video recording (refer to FIG. 5).

The second video encoder 160 encodes the guide image generated by the guide image generator 130 and outputs the encoded guide image to the controller 170.

The guide image may have a time (or length) or size equal to the time (or length) or size of the impact recording image.

For example, if the recording time of the shock recording image (or the shock image) is 10 seconds after the occurrence of the shock (event), the length of the guide image file is 10 seconds (i.e., 10 seconds of playback time). However, the guide image may actually be smaller than the time (or length) or size of the shock recording image.

The guide image includes at least one of (1) a message indicating that a shock event has occurred (e.g., a shock event has occurred), (2) a location where the shock recording image file is stored File name (e.g., Event / evt_xxxx.avi) information (see FIG. 5).

The control unit 170 inserts the guide image into the disconnected section of the still image to generate a normally recorded image file having a predetermined size or length (i.e., a predetermined file size or file playback time) at all times ). That is, the always-recorded video is transmitted before / after the guide image (the front part or the rear part), and the always-recorded image including the guide image is displayed at a predetermined time (for example, 1 minute) or a file size And stored.

The impact sensor unit 180 detects an impact occurring during driving or stopping (or parking) by using an impact sensor (or motion sensor) such as a kind of acceleration sensor, Signal.

The controller 170 controls the overall operation of the black box device for a vehicle and can be implemented as a kind of application processor (AP).

The control unit 170 receives the video image (for example, a still image, an event recording image, and the like) photographed through the camera unit 110 and stores the received image in the storage unit 190. The control unit 170 may include an internal memory (not shown). The control unit 170 buffers an image photographed by the camera unit 110 through the internal memory (not shown) having a high memory access speed, (190).

The storage unit 190 is a kind of nonvolatile memory such as a flash ROM and is typically an external memory type removable disk such as a Mini SD card, an SD card, or a USB memory. Therefore, even if the power supply to the storage unit 190 is interrupted, the stored data is not lost.

3 is a flowchart illustrating a method of controlling a black box device for a vehicle according to an embodiment of the present invention.

As shown in FIG. 3, the controller 170 starts to store the normal recording image file (or the normal recording file) in the storage unit 190 at the same time that the driving power is applied to the black box (S101).

If an event (e.g., an event) occurs during the storage of the normally-recorded image file as described above (YES in S102), the controller 170 stops storing the normally-recorded image file (S103) and generates an impact recording file S104).

For example, the shock recording image file (or the shock recording file) may be a file of a shock recording picture file (or a shock recording file) in which a picture taken before a predetermined time (for example, 10 seconds) File.

The control unit 170 stores the generated shock recording image file in the storage unit 190 (S105).

The shock recording image file is stored in another folder in the storage unit 190. [ The creation and storage of the shock recording image file are repeated each time an impact occurs.

When the occurrence of the impact (event) is terminated (YES in S106), the controller 170 ends storing the shock recording image file (S107).

However, as described above, when the impact recording is performed, the normally recorded video is interrupted (refer to FIG. 1), so that the user can mistake that the normally recorded video is not normally stored, The image is stored in a state of being disconnected, thereby causing a problem of file fragmentation.

Therefore, when the normally-recorded video is interrupted due to the occurrence of an event (shock), the controller 170 inserts the interrupted video in the interrupted interval of the normally-recorded video, (S108). ≪ / RTI >

At this time, the guide image includes 1) a message that a shock event has occurred (e.g., a shock event has occurred), 2) a position where the shock recording image file is stored (i.e., a folder of the memory card) (E.g., Event / evt_xxxx.avi) information (see FIG. 5).

Then, the control unit 170 inserts the created guide image into a break interval of the still image file and stores the inserted guide image in step S109.

In other words, the controller 170 inserts the guide image into the disconnected section of the normally recorded image to generate a normally recorded image file having a predetermined file size or length (i.e., a playback time) (see FIG. 4). That is, when a break interval occurs in the normally-recorded image, the controller 170 inserts the guide image into the break interval, generates one normally-recorded image file having a predetermined length or size, 190).

The control unit 170 repeats the steps S101 to S109 until the start of the vehicle is completed, the power supplied to the black box is cut off, or the video recording is terminated by the user's operation (S110).

FIG. 4 is a diagram illustrating a method of inserting and storing a guide image in a normally-recorded image in a black box device for a vehicle according to an embodiment of the present invention.

4, when an event (impact) occurs during normal recording, the black box according to the present exemplary embodiment is set to a predetermined time (i.e., an event recording time) (e.g., 10 seconds) A guide image including a guide message related to the event recording image is inserted in a break section of the normally recorded image to be generated.

Then, the always-recorded video file in which the guide image is inserted is stored in units of predetermined size or length.

FIG. 5 is a diagram illustrating an example of a guide image screen in FIG.

At this time, since the guide image screen is illustrated to facilitate the understanding of the invention, it may be changed to another guide message in actual application, and other information related to the impact recording image (or event recording image) may be additionally included.
