Image.Memory module 220 may include a buffer storage, one built-in memory/hard disk or can support one it is external action memory/
The module of hard disk, for storing related setting when image data or drive recorder 200 operate.Frequency circuit 230 can be one
Quartz crystal oscillator operates required reference frequency signal for providing drive recorder 200.Control module 240 can be one
Rear end controls chip, for controlling the running of each component in drive recorder 200.Image recording module 250 may include one or
Multiple images logging modle 20, a frequency circuit 23 and a processing circuit 24.
It can be communicated between control module 240 and image recording module 250 by coffret 270, coffret 270 wraps
Multiple channels are included, image recording module 250 can be passed an a data-signal DATA and wake-up signal MD by coffret 270
It send to control module 240, and control module 240 can be by coffret 270 by an I2C sequence datas/address signal, a core
Piece selection bus (chip select bus) signal CSB and frequency signal CLK is sent to image recording module 250.
Drive recorder 200 can whether an external power supply be received according to power supply module 260 and judge whether this into
One drive mode of row or a car-parking model：When power supply module 260 receives an external power supply, then drive recorder 200 can
Into drive mode；When power supply module 260 does not receive an external power supply, then drive recorder 200 can enter parking mould
Formula.
Under drive mode, all components are all to open in drive recorder 200, and power supply module 260 can be by this time
Cigarette lighter power provides in vehicle, and I2C sequence datas/ground that image recording module 250 can be transmitted according to control module 240
Location signal, chip select bus signals CSB and frequency signal CLK to perform recording function, then the number that will be relevant to image frame
It is believed that a number DATA is sent to control module 24.Control module 24 can include image frame in screen according to data-signal DATA
Memory module 220 is stored on 210 or by data-signal DATA, also can image frame be included on screen 210 and be deposited simultaneously
Enter among memory module 220.
Under car-parking model, drive recorder 200 can close all components first, and power supply module 260 can be by this time
200 built-in batteries of drive recorder/internal battery or other vehicle electricity sources (such as vehicle accumulator) provide.Then, image
The frequency circuit 23 of logging modle 250 can periodically start capturing images circuit 20 to detect the variation of vehicle periphery, processing circuit
24 judge whether vehicle periphery occurs a particular event according to this again.If particular event occurs in the judgement of processing circuit 24, can send at this time
Go out wake-up signal MD to start control module 240, control module 240 restarts in drive recorder 200 other components to perform
Recording function.
In embodiments of the present invention, drive mode hypograph acquisition circuitry 20 can perform the recording function of better quality, example
Such as with the acquisition rate and HD image quality (1280*720 resolution ratio) of 30 pictures per second (frame per second, FPS) come into
Row video recording；When not yet detecting particular event under car-parking model, capturing images circuit 20 can only be periodically executed low image quality photograph
Function, such as every 30 second beats take the photograph the photo of 1 VGA image quality (640*480 resolution ratio)；When detecting specific thing under car-parking model
After part, capturing images circuit 20 can perform the recording function of lower quality, for example, with the acquisition rate of 15FPS and HD image quality come into
Row video recording is recorded a video or is come with the acquisition rate of 15FPS and VGA image quality with the acquisition rate and VGA image quality of 30FPS
It records a video.The low picture performed under car-parking model compared to the better quality recording function performed under drive mode, the present invention
The energy consumption of matter camera function is at a fairly low, and the low quality recording function energy consumption that can be just performed when detecting particular event is also relatively low,
Therefore the stand-by time of capturing images circuit 20 can be significantly increased.
Particular event may be any variation that vehicle periphery occurs, such as pedestrian or close other vehicles.At this
In the drive recorder 200 of inventive embodiments, processing circuit 24 can be a low power consuming signal processing circuit, can be in different ways
To determine whether particular event occurs.For example, after car-parking model is entered, processing circuit 24 may compare capturing images circuit
20 pictures taken in front and rear startup twice, if difference is big each other for the image parameter (such as brightness or chroma) of two pictures
In a predetermined value, processing circuit 24 can then judge that particular event occurs in vehicle periphery.
In the drive recorder 200 of the embodiment of the present invention, frequency circuit 23 can be a low power consuming oscillator, for providing
Image recording module 250 operates required reference frequency signal.During due to performing low image quality camera function under car-parking model, this
Invention image acquisition circuitry 20 does not need to the FREQUENCY CONTROL of pinpoint accuracy, therefore compared to frequency circuit 230, frequency circuit 23
It can only need to provide inefficient energy running, but it is also relatively low to consume energy.
After normal mode is entered, the drive recorder 200 of the embodiment of the present invention also can separately perform frequency calibration.For example,
The frequency signal CLK that frequency circuit 230 generates can be sent to image recording module 250 by control module 240 so that frequency circuit
23 can adjust its output according to this.So after next time enters car-parking model, each other can between frequency circuit 230 and frequency circuit 23
It is enough synchronous.
The present invention can provide the drive recorder of a kind of low power consuming and multi-mode：It can record startup procedure under drive mode,
Therefore live evidence can be provided in the event of an emergency；Start recording it can then stop when detecting particular event under car-parking model
Image around vehicle place, therefore can be stolen in vehicle or provide evidence when being hit by its vehicle.
The foregoing is merely the preferred embodiment of the present invention, all equivalent changes done according to the claims in the present invention are with repairing
Decorations should all belong to the covering scope of the present invention.
