Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording device for compressing and recording information, and a motor vehicle equipped with the information recording device.

[0002]

2. Description of the Related Art In recent years, with the development of the multimedia industry, application software (hereinafter, referred to as an application) for handling images and audio data (hereinafter, image data will be described as an example) has been widely used. Generally, image data has a large data amount. In the above-described application, the huge image data is not used as it is, but the compressed image data is used. As this data compression method, for example, MPE
G (Moving Picture Experts
Group) standard system.

FIG. 10 shows a partial configuration of an information recording apparatus for recording image data obtained by photographing means. In this information recording apparatus, photographed image data is compressed by an encoder and recorded in a predetermined memory block. This information recording apparatus has two field memories 105A, 105A for temporarily storing image data.
06A, switch A1, switch A2, encoder 10
3A and the memory block 104, and a plurality (for example, three in FIG. 10) of similar configurations. In the following description, one of the four configurations will be described unless otherwise specified. When the photographing means photographs the object, the switch A1 is switched to a predetermined contact and recorded in the field memory 105A. At this time, the image packet data sent by the photographing means to the field memory 105A is fragmentary. The moving image data stored in the field memory 105A is, for example, stored in the MPEG1 encoder 103A when the switch A2 is switched.
Are recorded in the memory block 104 while being encoded.

[0004] The memory block 106A is provided additionally because the image packet data is transferred to the encoder 10A.
This is because the image packet data photographed by the photographing means cannot be written to the field memory 105A during encoding by 3A, and is written to the memory block 106A during that time. In other words, the field memories 105A and 106A are used alternately to accumulate image packet data, and are continuously compressed by the encoder 103A (real-time encoding). The compressed image data is stored in the memory block 14. As described above, recording in the memory block 104 by a plurality (four in FIG. 10) of the encoders 103A to 103D is performed so that the image data recorded in the memory block 104 can be reproduced at a later date to facilitate analysis. This is because the image data of each photographing means is recorded in the memory block 104.

[0005]

However, in order to encode the image packet data by the plurality of encoders 103A to 103D as described above, the encoder 1
The processing of a control unit (not shown) for controlling 03A to 103D and the like becomes complicated. Also, each encoder 103A
The frame memories 105A and 106A are required for each of the to 103D (in FIG. 10, four pairs of frame memories are required). Therefore, in this information recording device, control of the encoder becomes complicated, and a large number of encoders are required.
The capacity and number of frame memories need to be large.

Accordingly, the present invention solves the above-mentioned problems, and comprises at least one compression means and a small-capacity second storage means, thereby facilitating control when compressing and recording acquired information. It is an object of the present invention to provide an information recording apparatus having a simple configuration and high reliability, and a vehicle equipped with the information recording apparatus.

[0007]

SUMMARY OF THE INVENTION The object of the present invention is to integrate a plurality of information acquisition means for simultaneously acquiring a plurality of information with a plurality of information acquired by the information acquisition means. Means for performing integration, first storage means for storing integrated information integrated by the integration means, compression means for compressing the integrated information in the first storage means, and compression compressed by the compression means. A second storage unit for storing information, an information acquisition unit, a first storage unit,
The present invention is achieved by an information recording apparatus having a compression unit and a control unit for controlling the second storage unit. According to the present invention, the plurality of information acquisition units respectively acquire the plurality of information, the integration unit integrates the plurality of information, and the integrated information is stored in the first storage unit. The integrated information stored in the first storage unit is compressed by the compression unit. The compressed compression information is stored in the second storage unit. Since the integrated information stored in the second storage means is compressed and stored, the second storage means requires only a small capacity. Also, since the information acquired by the plurality of information acquisition units is integrated in the compressed information stored in the second storage unit, at least one compression unit may be used. The control means of the information recording apparatus can be simplified because the number of first storage means and compression means to be controlled is small. In addition, since the compressed information stored in the second storage unit includes the respective information obtained by the plurality of information acquisition units, it is not necessary to synchronize the respective information. Therefore,
The information recording device can have a simple configuration.

The state in which the third camera unit 7c and the second camera unit 7b are each switched in-house (hereinafter, referred to as security mode) as shown in FIG.

The accident mode is a mode that operates when, for example, a driver encounters an accident while riding in the automobile 100. The security mode is a mode that operates when, for example, someone enters while the automobile 100 is parked. Regarding these actual detailed operations, etc.,
It will be described later.

FIG. 4 is a block diagram showing a configuration example of an information recording / analyzing apparatus including the recorder and the analyzing computer of FIG. The emergency system 2 (information recording / analysis device) includes the recorder 1 and / or the analysis computer 5.
Has zero. The information recorded by the recorder 1 (hereafter, image data is mainly described as an example)
For example, the memory card 5 (storage means, second storage means, emergency memory block) is delivered to the analysis computer 50. The memory card 5 is an information recording medium that is detachable from each of the recorder 1 and the analysis computer 50. Examples of the information recording medium other than the memory card include an optical disk such as a memory stick and a mini disk (MD).

As shown in FIG. 5, the recorder 1 includes a first camera unit 7a (information acquisition unit and photographing unit) and a second camera unit 7b.

Means), a display unit 8 (display means) and a positioning unit 20 (information acquisition means, positioning means).

The first camera section 7a to the fourth camera section 7d are
For example, for each CCD (Charge Coupled)
Device) is an imaging device using an imaging element.
The first camera unit 7a to the fourth camera unit 7d, the positioning unit 20, and the recording / control unit 30 are connected to a LAN (Local Area) using a connection method that satisfies, for example, the specification of the IEEE 1394 standard.
a Network), for example, in a so-called daisy chain format.
Daisy chain connection (hereinafter referred to as LAN connection as an example) means that each device is connected in a chain by a predetermined signal line such that one output terminal is connected to an input terminal.

As described above, since the first camera unit 7a to the fourth camera unit 7d, the positioning unit 20, and the recording / control unit 30 are respectively connected to the LAN, high-speed data as defined in the IEEE 1394 standard. Transmission can be realized.
In particular, when transmitting image data or the like, a large amount of data can be transmitted in a short time, so that the effect is large. Also, there is no need to perform complicated dedicated wiring processing or the like for each device as conventionally required, and connection is easy.

The first camera section 7a is disposed on the right fender mirror 10 when viewed from above the automobile 100, for example, as shown in FIG. 1, and its direction is adjusted so as to face the rear 100b. The fourth camera unit 7d is disposed on the left fender mirror 10 when viewed from above the automobile 100 as shown in FIG.

In the security mode, the second camera section 7b is set so as to face forward 100a (for example, inside the vehicle). In this way, the direction of the second camera unit 7b can be switched by, for example, operating a predetermined changeover switch 11 by a driver and controlling the recording / control unit 30 described later to rotate the motor and other actuators. The moving first switching unit 14 operates to switch the direction of the second camera unit 7b. Thus, the security mode is entered.

When the driver operates the changeover switch 11 again, the direction of the second camera section 7b in the security mode and the direction of the accident mode can be continuously switched. The third camera unit 7c is a second camera unit 7c.
The operation is substantially the same as b. The difference is that the second camera unit 7
The point is that the direction in each mode b is reversed. In other words, the third camera unit 7c shoots in the accident mode by facing the front 100a in the accident mode by operating the second switching unit 15 and shoots substantially in the rear 100b (for example, in the vehicle) in the security mode.

Therefore, in the accident mode,

The microphone 18 is connected to the recording / control unit 30 and is a voice obtaining unit for obtaining voice (information). This audio is acquired in synchronization with the video described above. The sensor unit 13 is connected to the recording / control unit 30, and is an action sensor such as an acceleration sensor for detecting an impact and / or an infrared sensor for detecting a motion of a person. Examples of the acceleration sensor include a silicon element type sensor, a sensor combining a reed switch and a magnet, a piezoelectric ceramic sensor, and the like. When the sensor unit 13 detects a predetermined amount of impact (for example, an impact at the time of an accident or a slight vibration of vandalism at the time of stopping and / or a movement of a person such as the surroundings), a trigger signal is sent to the recording / control unit 30. Generate TG. The display unit 8 is, for example, a liquid crystal display, and is connected to the recording / control unit 30. The display unit 8 is provided in front of the driver's seat of the automobile 100.

The operation of recording the information obtained by the first camera unit 7a to the fourth camera unit 7d or the like by the trigger signal TG is started. Image data captured by the first camera unit 7a to the fourth camera unit 7d is fragmentarily sent to the integration unit 37 via the LAN connection. The unifying means 37 transmits, for example, fragmentary image data from the first camera unit 7a or the like to which a predetermined identifier has been added (the first packet data 42 in FIG. 7).
Etc.) (the integration means 37 may acquire data such as the first packet data 42 in FIG. 7 from each device). The integrating means 37 transmits the information of each of the camera units 7a to 7d to the first frame memory 31 or the second frame memory 32 by switching the received first packet data 42 and the like to the first switch 34 as follows. Writing is performed so as to be integrated in synchronization (writing integrated information).

The first switch 34 is turned on at the contact 34 a under the control of the control unit 39, and the first packet data 4

On the other hand, image data for each camera unit stored in the first frame memory 31 and the like is, for example, 32
It is a FullColor of 0 pixels × 240 pixels. That is, the first frame memory 31 and the like
Image data of the three camera units 7a to 7d can be stored. 20 to 3 as image data of this resolution
If the image is taken for 0 seconds and compressed as described later, the moving image data has a relatively small capacity. Therefore, it can be stored in the memory card 5.

The second switch 35 is turned on at the contact 35 a under the control of the control unit 39, and the first packet data 4
2 is a first encoder 38 controlled by the controller 39.
For example, MPEG2 (Moving Pictu)
It is compressed in re Experts Group 2) format.

The compressed compressed image data (compression information) and the like are written (stored) in the memory card 5 mounted on the connection unit 30e. While the data is being written to the memory card 5, the second packet data 43 captured by each of the camera units 7a to 7d is sent to the first switch 34 via the connection unit 30d. When the first encoding unit 38 finishes the processing, the control unit 39 turns on the first switch 34 and the second switch 35 at the contacts 34b and 35b, respectively, and continuously compresses them in substantially the same manner (real-time encoding). Image data and the like are recorded on the memory card 5.

For example, by performing substantially the same processing, audio data and position information data are recorded in the memory card 5 in synchronization with moving image data (hereinafter, mainly image data will be described). .

Therefore, the memory card 5 has a plurality of (for example, four in this description) synchronized camera units 7a to 7a.
Since the image information d is recorded, editing such as reproduction can be easily performed later.

It is a processing unit for encoding (converting) into data of a format. The image data and the like encoded by the second encoding unit 57 are recorded in the external storage unit 54. The second decoding unit 56 (CODEC) includes, for example, MotionJ
This is a processing unit for decoding PEG format data.

Motion JPEG format data is MPE
Unlike the moving image data of the G2 format, the moving image data is converted into still image data one by one.
Moving image data or the like that has been G2 format data can be played back frame-by-frame or as speed-changed playback as still image data by predetermined playback software. Further, as described above, for example, the four camera units 7a to 7d
Since the image data taken by is synchronized,
In this playback software, four camera units 7a to 7d
Can be referred to at the same time.

The operation of the above configuration will be briefly described with reference to FIGS. The recorder 1 described above is mounted on the accident mode vehicle 100. The driver exits the security mode described later by pressing the switch button 11 before transmitting the car 100. The recording / control unit 30 has a switch button 11
Is switched to the accident mode in response to a signal from the controller, the first switching unit 14 and the second switching unit 15 are driven, and the second camera unit 7b and the third camera unit 7c are photographed in the directions shown in FIG. Switch to The driver starts driving the automobile 100. The first provided in the recorder 1
The camera units 7a to 7d, the microphone 18, the positioning unit 20, and the like are in operation, and the image data is displayed on the display unit 8, for example. In this state, the recording / control unit 3
By the control of 0, no data is recorded on the memory card 5. The driver is, for example, involved in a traffic accident.

The recorder 1 has a sensor unit 13 as shown in FIG.
Is provided, and the sensor section 13 gives a predetermined trigger signal TG to the recording / control section 30 by an impact at the time of an accident. The recording / control unit 30 detects the trigger signal TG and converts the image data, audio data, and position data acquired by the first camera unit 7a to the fourth camera unit 7d, the microphone 18, the positioning unit 20, and the like, as described above. As described above, the integration means 37 of the recording / control unit 30 is connected to each camera 7a
A plurality of image data and the like obtained by 7d to 7d are integrated, written into the first frame memory 31 and the like, and compressed and recorded on the memory card 5 for a predetermined time (for example, about 20 to 30 seconds). The recording of the information by the recorder 1 is compressed, for example, before and after the recording / control unit 30 receives the trigger signal TG. The recording time can be increased or decreased as long as the capacity of the memory card 5 permits, by changing the set time of a timer unit (not shown) provided in the recording / control unit 30.

The memory card 5 is thereafter collected and analyzed by the analysis computer 50 as follows. The memory card 5 stores, for example, image data compressed in the MPEG2 format. The analysis computer 50 once restores the MPEG2 format data as described above, and converts the moving image data into, for example, Motion.
The data is converted into JPEG format data and stored in an external storage unit 54 such as a hard disk. Analysis computer 50
Since the image data stored in the external storage unit 54 is still image data for each image, analysis of the image data and the like can be performed in detail.

Security Mode The owner of the vehicle 100 has stopped the vehicle 100 at an arbitrary location. However, someone did harm to the car 100. As in the case of the accident mode, the sensor unit 13 detects this impact. When the recording / control unit 30 detects the trigger signal TG of the sensor unit 13, the recording / control unit 30 drives the first switching unit 14 and the second switching unit 15 to cause the second camera unit 7b and the third camera The unit 7c is switched so as to take an image as shown in FIG. 3 (for example, in a car). In the security mode, the recorder 1 records the situation around the automobile 100 on the memory card 5 immediately after detecting the trigger signal TG, for example.

By analyzing the recorded image data and the like in detail in the same manner as in the accident mode, the criminal image can be quickly determined.

The integrated information stored in the first frame memory 31 or the second frame memory 32 is compressed by the first encoding unit 38. The compressed compression information is stored in the memory card 5.

Since the integrated information stored in the memory card 5 is compressed and stored, the memory card 5 requires a small capacity. In addition, since the information acquired by each of the plurality of camera units 7a to 7d is integrated into the compressed information stored in the memory card 5, at least one first encoding unit 38 is sufficient. The control unit 39 of the information recording apparatus can simplify the first frame memory 31 or the second frame memory 32 to be controlled and the first encoding unit 38 because the number is small. In addition, since the compression information stored in the memory card 5 includes respective information from the plurality of camera units 7a to 7d,
There is no need to synchronize each information.

According to the embodiment of the present invention, at least one first encoding section 38 for encoding image data or the like is required, and the capacities of the first frame memory 31 and the second frame memory 32 are larger than in the prior art. Less is needed. In addition, since the number of components to be controlled by the control unit 39 is reduced, the control of the control unit 39 can be simplified. Therefore, the recorder 1 has a simplified circuit configuration and can be downsized. Further, the number of components can be reduced to reduce the cause of failure, and the reliability of the recorder 1 can be improved.

The present invention is not limited to the above embodiment. A preferred embodiment of the present invention may be applied to any monitoring apparatus that performs a predetermined monitoring, not only a vehicle, but also a moving object. In addition, the present invention is not limited to a parked car and can be applied to the above-described stopped state of the moving body. The means for delivering information from the recorder to the analysis computer is not limited to a memory card, but may be any information storage medium capable of information writing / rewriting (removable). The recorder may be provided with a function for decoding the MPEG2 format data, so that the recorded information can be immediately displayed on the display unit in the automobile instead of in the analysis computer.

[0045]

As described above, according to the present invention, at least one compression unit and a small-capacity second storage unit are provided, so that control for compressing and recording acquired information is easy. By doing so, it is possible to provide a highly reliable information recording device having a simple configuration and a vehicle equipped with the information recording device.
