Description
Technical field
The utility model belongs to image display technology field, and in particular to a kind of device for reducing power consumption.
Background technology
Image pixel is typically to be made up of the rectangular matrix horizontally and vertically arranged, and the scanning for pixel has progressive scan
With interlacing scan two ways.Progressive scan is to carry out the scanning in horizontal direction, referred to as line traversal from left to right, then
Be quickly returned to left end, referred to as row scan retrace from right-hand member again, particles once, a referred to as line-scanning period.During scanning
The scanning carried out from top to bottom in vertical direction is referred to as field scan trace, after trace terminates, scans from lower end and is rapidly returned to
End, this process are referred to as field scan flyback.Interleaved method is that a two field picture is divided into two to be scanned, first from upper and
Scan the odd-numbered line in every two field picture lowerly, after whole odd-numbered lines in scanning through a two field picture, return image upper end according to
Even number line in one two field picture of secondary scanning, so, a two field picture passes through two field scans, and all pixels can all have been swept.Image
Trace transmission is picture signal, and flyback transmission is blanking signal and synchronizing signal.The picture that final image is shown is figure
The signal transmitted as trace.
At present, with the improvement of people's life quality, possessing many intelligence such as portable, flexible record and functional diversity
Wearable increasingly turns into electronic equipment indispensable in people's daily life.Yet with portable purpose, generally may be used
Wearable device volume is all smaller, and no image of Buddha mobile terminal equally carries high capacity cell.Therefore how to reduce electronic equipment or
The power consumption of person's image display is urgent problem to be solved.
Utility model content
In order to solve the above problems, the utility model provides a kind of device for reducing power consumption, passes through intelligent dynamic management control
Disconnection and the closure of switch are made, effectively solves the problems, such as imaging sensor, electronic equipment or other image display high power consumptions.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of device for reducing power consumption, including the power module for power supply；For obtaining image during image scanning
The picture signal of trace transmission and the acquisition module of image inverse-range signal；For analyze identification acquisition module collection signal and
According to the processing module of analysis judged result control function module；Some functional modules：According to the order of processing module to signal
Carry out corresponding function processing；Some controlling switches：Each controlling switch connection One function module, for control function module
Start and stop.
Further, reducing the device of power consumption also includes low pressure difference linear voltage regulator LDO, is connected, is used for power module
Filtering and regulated output voltage.
Preferably, processing module is digital signal processor DSP, micro- device MCU processed or integrated based on MCU and DSP architecture
One kind in chip.
Compared with prior art, the beneficial effects of the utility model：
The utility model can be by intelligent dynamic management controlling switch closure and disconnection, effectively reduce circuit power consumption,
One controlling switch will be set before each functional module, what image trace transmitted during collection image scanning is picture signal,
The transmission of image flyback is blanking signal and synchronizing signal, not display image, in image flyback sequential processing module control open
Shut-off is opened, and reduces power consumption, and in image trace sequential, processing module controls the control before the corresponding function module to open according to demand
Conducting is closed, the signal after processing is transmitted to the processing of corresponding functional module.The utility model according to demand selectively will control
Switch conduction or disconnection, reach the purpose for reducing power consumption.The utility model can be widely applied to imaging sensor, mobile phone and
On the smart machines such as other wearings, power consumption is effectively reduced.
Brief description of the drawings
Fig. 1 is schematic device of the present utility model；
Fig. 2 is the scanning sequence figure of the utility model acquisition module.
Embodiment
With reference to Fig. 1 and Fig. 2, embodiment of the present utility model is elaborated, the present embodiment is new with this practicality
Implemented under premised on type technical scheme, give detailed embodiment and specific operating process, but the utility model
Protection domain be not limited to following embodiments.
The utility model discloses a kind of device for reducing power consumption, including the power module for power supply, for filtering and
The low pressure difference linear voltage regulator LDO of regulated output voltage, power module are connected with low pressure difference linear voltage regulator LDO；For obtaining
The blanking signal of picture signal and image flyback transmission and the acquisition module of synchronizing signal that image trace is transmitted in image scanning,
Not display image during image flyback；For analyzing and identifying the signal of acquisition module collection and according to analysis judged result
The processing module of control function module, in the present embodiment, processing module can be digital signal processor DSP, microcontroller
One kind in MCU or integrated chip based on MCU and DSP architecture, is not especially limited；Some functional modules：According to processing mould
The order of block carries out corresponding function processing to signal；Some controlling switches：Each switch connection One function module, for controlling
The start and stop of functional module.
The key point of the utility model device is respectively provided with a controlling switch before being each functional module, with image trace
It is condition with image flyback, is analyzed and identified by processing module, disconnection and the closure of corresponding controlling switch is controlled, to realize phase
Answer the power supply and power-off of functional module；I.e. when signal is image flyback sequential, processing module transmission order is by before functional module
Controlling switch disconnect, not to functional module power；When signal is image trace sequential, processing module is believed the image of collection
Number processing, and according to demand control the corresponding function module before controlling switch conducting so that functional module is to the further place of signal
Reason, while processing module controls the controlling switch before other functional modules to remain off, and reaches the purpose of energy-conservation.This practicality
New device changes the pattern that functional module on traditional approach is constantly in power consumption state, realizes administration of energy conservation, effectively drop
Low circuit power consumption.
