ビデオ出力端子15等から構成される。 It consists of a video output terminal 15 and the like.

【0008】CCDカメラ1は車両走行時の主として前方の状況を撮影し、その画像情報であるビデオ信号を信号処理ユニット7内のA/D変換器8でデジタル信号に変換し、デコーダ9で処理して画像圧縮回路10で画像圧縮してからランダムアクセスメモリ12に記録される。 [0008] CCD camera 1 mainly taking forward the status at the time the vehicle is running, and converted into a digital signal by the A / D converter 8 signal processing unit 7 the video signal which is the image information, processed by the decoder 9 and image compression by the image compression circuit 10 is recorded in the random access memory 12 after.

【0009】同時に各センサ2〜6からの各感知情報は制御回路11に制御されて圧縮画像情報と共にランダムアクセスメモリ12に記録される。 [0009] is recorded in the random access memory 12 with the same time each sensing information compressed image information is controlled by the control circuit 11 from the sensors 2-6. メモリ12は、例えば、16枚用意されていて、最新の情報を記録する時には、最古の情報は消去され、エンドレスにたえず最新の情報を記録するように制御回路11により制御される。 Memory 12 is, for example, have been prepared 16 sheets, when recording the latest information, the oldest information is deleted, is controlled by the control circuit 11 so as to constantly record the latest information endlessly.
この場合、記録のタイミングは任意の同期で設定することができる。 In this case, the timing of the recording can be set at any synchronization.

【0010】図2は、メモリ12のメモリ領域の構成例を示し、12aは画像情報メモリ領域、12bはセンサ情報メモリ領域である。 [0010] Figure 2 shows a configuration example of a memory area of ​​the memory 12, 12a is the image information memory area, 12b denotes a sensor information memory area. 図3はメモリ12に記録される情報の構成を示し、例えば、1〜32ページの記録容量を有し、各ページには、日付/時間データ、車両データ(センサ情報)、圧縮画像データ等が格納される。 Figure 3 shows a configuration of information recorded in the memory 12, for example, it has a recording capacity of 1 to 32 pages, each page, date / time data, vehicle data (sensor information), such as compressed image data It is stored.

【0011】今、事故発生により衝突センサ2が作動した時、制御回路11からランダムアクセスメモリ12に書き込み禁止が命令され、各情報の記録を停止させる。 [0011] Now, when the collision sensor 2 is actuated by accident, write inhibit the random access memory 12 is commanded from the control circuit 11 to stop the recording of each information.
これと同時に停止直前の最新の記録情報がメモリ12からフラッシュメモリ13に転送して記録され、事故発生時に電源がオフされることがあっても、記録情報が消去されないようになっている。 Latest record information immediately before stopping at the same time is recorded in the transfer from the memory 12 to the flash memory 13, the power supply during an accident occurs even be turned off, the recording information is prevented erased. 事故解析を行なうに当っては、フラッシュメモリ13に記録された情報を、エンコーダ14で圧縮画像情報の伸張等の信号処理を施し、ビデオ出力端子15より事故直前の画像及びセンサ情報を再生することができる。 Is hitting the performing accident analysis, the information recorded in the flash memory 13, performs signal processing such as expansion of compressed image data by the encoder 14, to reproduce an image and sensor information of the accident immediately before from the video output terminal 15 can.

【0012】図4は再生画像の一例を示す。 [0012] Figure 4 shows an example of the reproduced image. 図5は上述した本発明装置の動作フローチャートである。 Figure 5 is an operational flowchart of the present invention apparatus described above. 同図において、ステップS1ではCCDカメラ1により車両前方の画像を撮影し、ステップS2でその画像の前記した信号処理を行なってメモリ(RAM)12に記録すると同時にステップS3で車速、操舵角、ブレーキ圧力、加速度等のセンサ情報をメモリに記録する。 In the figure, taking pictures ahead of the vehicle by the CCD camera 1 in step S1, the vehicle speed in step S3 and at the same time recorded in the memory (RAM) 12 by performing the signal processing of the image in step S2, the steering angle, brake pressure, recording the sensor information such as acceleration in a memory. ステップS4では衝突センサ2が作動するか否かを判定し、作動しない時はステップS1に戻るが、作動すればステップS5でメモリ12の記録情報をフラッシュメモリ13に転送して記録し、ステップS6でメモリ13の記録情報の画像を再生する。 Collision sensor 2 in step S4 it is determined whether or not to operate, but returns to Step S1 when not actuated, to transfer the record information in the memory 12 to the flash memory 13 and recorded in step S5 if actuated, step S6 in reproducing the image of the recorded information in the memory 13.

【0013】図6は前記各センサ2〜6及びCCDカメラ1の配置を例示している。 [0013] Figure 6 illustrates the arrangement of the sensors 2-6 and CCD camera 1. この例では、特に車室内に車室カメラ16を設け、運転席17でのドライバーの運転状況も記録するようにしている。 In this example, in particular a passenger compartment camera 16 provided in the passenger compartment, so that also recorded operating condition of the driver in the driver's seat 17. これによれば、脇見運転や、居眠り運転等があったかなどを検証することができる。 According to this, it can be verified and whether there inattentive driving or is drowsy driving, and the like. なお、前記ランダムアクセスメモリ12に代えてビデオテープレコーダを用いても良い。 It is also possible to use a video tape recorder instead of the random access memory 12. この場合は、 in this case,
フラッシュメモリ13は不要である。 Flash memory 13 is not required.
