1 is a view for explaining the configuration of a vehicle image processing apparatus according to an embodiment of the present invention.

The vehicle image processing apparatus 100 is also referred to as a vehicle black box apparatus.

Referring to FIG. 1, the vehicle image processing apparatus includes a camera module 101, a microphone 102, a signal processing unit 103, a storage unit 104, a communication unit 105, a power supply unit 106, a control unit 107, It may include an impact detection unit 108, a location information module 109, a display 110, an audio output module 111, an external display device 112, an interface 113, and an input unit 120.

The camera module 101 may take an image of the front, rear, side, or interior of the vehicle and transmit it to the signal processing unit 103. The captured image may be stored in the storage unit 104 after being subjected to a compression process in the signal processing unit 103 or directly stored in the storage unit 104 without a compression process. The camera module 101 is composed of one camera depending on the system configuration, and only the front is photographed, or when composed of a plurality of cameras, the recording position of the camera in various ways according to the purpose of use such as front, rear, side, inside the vehicle, etc. You can set

The microphone 102 may record the voice or sound inside or outside the vehicle and transmit it to the signal processing unit 103. The recorded voice or sound may be transmitted to the signal processing unit 103 and passed through a compression process, and then stored in the storage unit 104 or directly stored in the storage unit 104 without a compression process. The recorded voice or sound is related to a sound caused by an external shock or a situation inside/outside a vehicle, and may help to recognize the situation at the time along with the video.

The signal processing unit 103 compresses to reduce the capacity of the image data photographed from the camera module 101. The image data has a form in which each frame is gathered several times along the time axis. That is, it can be regarded as a photograph taken continuously for a given time. Since the capacity of such an image is very large when it is not compressed, and it is very inefficient when it is stored in the memory as it is, compression must be performed on the digitally converted image. In video compression, correlation between frames, spatial correlation, and methods using visual characteristics sensitive to low-frequency components are used. Since the original data is lost due to compression, it must be compressed at an appropriate rate to identify the traffic accident situation of the vehicle. As a video compression method, one of various video codecs such as H.264, MPEG4, H.263, and H.265/HEVC can be used, and image data is compressed in a manner supported by the vehicle image processing apparatus 100.
