Embodiment
Fig. 2 is the functional block diagram of a driving register 200 among the present invention.Driving recorder 200 comprises a screen 210, a memory module 220, a frequency circuit 230, a control module 240, an image recording module 250, a power supply module 260, and a transmission interface 270.Screen 210 can be LCD Panel, is used for showing timely image or the image of previous record.Memory module 220 can comprise a memory buffer, one built-in memory/hard disk, or can support the module of an external action internal memory/hard disk, the related setting when being used for store images data or driving recorder 200 running.Frequency circuit 230 can be a quartz crystal oscillator, is used to provide the required reference frequency signal of driving recorder 200 runnings.Control module 240 can be a rear end control chip, is used for controlling the running of each assembly in the driving recorder 200.Image recording module 250 can comprise one or more recording image modules 20, a frequency circuit 23, and a treatment circuit 24.
Can communicate by letter by transmission interface 270 between control module 240 and the image recording module 250, transmission interface 270 comprises a plurality of channels, image recording module 250 can be sent to control module 240 with a data-signal DATA and a wake-up signal MD by transmission interface 270, and control module 240 can be sent to image recording module 250 with an I2C sequence data/address signal, a chip selection bus (chip select bus) signal CSB and a frequency signal CLK by transmission interface 270.
Whether drive recorder 200 can receive an external power source according to power supply module 260 and judge whether that this carries out a driving pattern or a car-parking model: when power supply module 260 receives an external power source, then drive recorder 200 can enter the driving pattern; When power supply module 260 does not receive an external power source, then drive recorder 200 can enter car-parking model.
Under the driving pattern, all component is all unlatching in the driving recorder 200, this moment, power supply module 260 can be provided by cigar lighter power supply in the vehicle, and I2C sequence data/address signal, chip selection bus signals CSB and frequency signal CLK that image recording module 250 can transmit according to control module 240 carry out recording function, and the data-signal DATA that will be relevant to again image frame is sent to control module 24.Control module 24 can be presented at image frame on the screen 210 according to data-signal DATA, or deposits data-signal DATA in memory module 220, also can simultaneously image frame is presented on the screen 210 and deposit among the memory module 220.
Under car-parking model, driving recorder 200 at first can be closed all component, and this moment, power supply module 260 can be by driving recorder 200 built-in battery/internal batteries, or other car electricity source (for example vehicle accumulator) provides.Then, the frequency circuit 23 of image recording module 250 can regularly start capturing images circuit 20 with the variation around the detection vehicle, and treatment circuit 24 judges according to this more whether vehicle periphery one particular event occurs.Particular event occurs if treatment circuit 24 is judged, can send wake-up signal MD this moment starting control module 240, control module 240 is restarted in the driving recorder 200 other assembly to carry out recording function.
In embodiments of the present invention, driving pattern hypograph acquisition circuit 20 can be carried out the recording function of better quality, for example record a video with acquisition speed and the HD image quality (1280*720 resolution) of 30 pictures of per second (frame per second, FPS); When not yet detecting particular event under car-parking model, capturing images circuit 20 can only regularly be carried out low image quality camera function, and for example per 30 second beats are taken the photograph the photo of 1 VGA image quality (640*480 resolution); After under car-parking model, detecting particular event, capturing images circuit 20 can be carried out low-qualityer recording function, for example record a video, record a video with acquisition speed and the VGA image quality of 30FPS with acquisition speed and the HD image quality of 15FPS, or record a video with acquisition speed and the VGA image quality of 15FPS.The better quality recording function of carrying out under the driving pattern, the low image quality camera function power consumption that the present invention carries out under car-parking model is quite low, and the power consumption of the inferior quality recording function that just can carry out when detecting particular event is also lower, therefore can significantly increase the stand-by time of capturing images circuit 20.
Particular event may be for any variation of vehicle periphery generation, for example when pedestrian or other vehicle approach.In the driving recorder 200 of the embodiment of the invention, treatment circuit 24 can be a low power consuming signal processing circuit, and it can judge whether to occur particular event by different way.For instance, after entering car-parking model, taken picture when treatment circuit 24 can compare capturing images circuit 20 and starts for twice in front and back, if difference is greater than a predetermined value each other for the image parameter of two pictures (for example brightness or chroma), 24 for the treatment of circuits can judge that particular event appears in vehicle periphery.
In the driving recorder 200 of the embodiment of the invention, frequency circuit 23 can be a low power consuming oscillator, is used to provide the required reference frequency signal of image recording module 250 runnings.Because when carrying out low image quality camera function under car-parking model, capturing images circuit 20 of the present invention does not need the frequency control of pinpoint accuracy, therefore compared to frequency circuit 230, frequency circuit 23 can only need provide low usefulness running, but power consumption is also lower.
After entering normal mode, the driving recorder 200 of the embodiment of the invention also can be carried out frequency calibration in addition.For example, control module 240 can be sent to image recording module 250 with the frequency signal CLK that frequency circuit 230 produces, so that frequency circuit 23 can be adjusted its output according to this.So after entering car-parking model next time, each other can be synchronous between frequency circuit 230 and the frequency circuit 23.
The present invention can provide a kind of low power consuming and multimodal driving recorder: can note down startup procedure under the driving pattern, therefore can provide on-the-spot evidence when emergency situations occurs; The next meeting of car-parking model begins to note down image around the parking site when detecting particular event, therefore can produce evidence when vehicle is stolen or is clashed into by its car.
The above only is the preferred embodiments of the present invention, and all equalizations of doing according to claim of the present invention change and modify, and all should belong to covering scope of the present invention.
