Description
[technical field]
The present invention relates to the communications field, relate in particular to a kind of method and device of stabilizing handhold equipment image.
[background technology]
At present; The quickening of Along with people's rhythm of life and work rhythm needs when much human is most to see the mobile phone on the car, handheld devices such as PDA, laptop computer, because the image on the handheld device constantly rocks with car in the driving process; Be easy to cause visual fatigue, if things go on like this affect one's power of vision unavoidably.Because human eye is just can see object at the moment clearly through the adjusting of eyes ciliary muscle, when seeing the relatively-stationary object of distance, the contraction of human eye ciliary muscle and extension just can keep relative stability, and it is tired that eyes also are not easy to feel; If object always is in vibrating state, eyes are in order to see target object clearly, and ciliary muscle will be compelled ceaselessly to regulate to see image clearly, when this adjusting is too much, overfrequency just causes kopiopia easily.
Existing market has part digital camera, video camera, telescope product that anti-trembling function is arranged; These products are obtained stabilized image has dual mode: one trembles for optics is anti-, and it is to rely on the structure of special camera lens or CCD photo-sensitive cell farthest reducing the operator in use because shake causes image unstable.The 2nd, electronic flutter-proof is to analyze to the image on the CCD, utilizes edge image to compensate then, and it just carries out post-processed to the data that collect, inconvenient operation and complicated steps, poor effect.
[summary of the invention]
The invention provides and a kind ofly can slow down method and the device that person very eliminates the stabilizing handhold equipment image of in rocking environment, seeing the visual fatigue that handhold equipment image causes.
In order to solve above technical matters, the invention provides a kind of method of stabilizing handhold equipment image, comprise step:
A), the sensor that starts in the handheld device rocks data to obtain;
B), the mimotope shifting signal in the step a) is converted to digital signal and sends to digital signal processor and central processing unit is handled, and through the reference position of display driver control display screen lattice array and scan line adjust the position of image and store.
The present invention also provides a kind of device of stabilizing handhold equipment image; Comprise central processing unit (CPU), sensor, analog-to-digital conversion module, digital signal processor and display screen, said sensor, analog-to-digital conversion module, digital signal processor, CPU and display screen are connected in order.
The device of above-described stabilizing handhold equipment image also comprises Asynchronous Serial Interface and display driver, and said Asynchronous Serial Interface is connected between analog-to-digital conversion module and the digital signal processor; Said display driver is connected between central processing unit and the display screen.
The device of above-described stabilizing handhold equipment image also comprises storer, and said storer connects with CPU.
The device of above-described stabilizing handhold equipment image, said sensor are dual spindle gyroscopes, and first, second of said dual spindle gyroscopes connects with said analog-to-digital conversion module respectively.
The method of stabilizing handhold equipment image of the present invention and device are because of built-in sensors in handheld device; Can obtain the displacement data that rocks of image in good time; And through analog-to-digital conversion module and signal processor processes; Thereby the display position of adjustment image so that the relative displacement between human eye and the image keeps fixed value, thereby alleviates that image rocks and the visual fatigue that causes.
The method of stabilizing handhold equipment image of the present invention and install easy to operate, simple in structure, and very practical.
[description of drawings]
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is the process flow diagram of the method embodiment 1 of stabilizing handhold equipment image of the present invention.
Fig. 2 is the structured flowchart of the device embodiment 1 of stabilizing handhold equipment image of the present invention.
[embodiment]
The method of stabilizing handhold equipment image of the present invention comprises step: the sensor that starts in the handheld device rocks data to obtain; The data of rocking that sensor is obtained convert digital signal to through analog-to-digital conversion module, after the Asynchronous Serial Interface coupling, send digital signal processor to; Digital signal processor passes through the position of the reference position of display driver control display screen lattice array and scan line with the adjustment image; Thereby keep the image display position relatively stable, to reduce the user sees handhold equipment image under the environment that rocks visual fatigue.
The device of stabilizing handhold equipment image of the present invention comprises CPU, sensor, analog-to-digital conversion module, digital signal processor, Asynchronous Serial Interface, display driver, display screen and storer; Said sensor, analog-to-digital conversion module, Asynchronous Serial Interface, digital signal processor, CPU, display driver and display screen are connected in order; Said storer is connected with CPU.
In the present invention, said sensor is a dual spindle gyroscopes.
In the method embodiment 1 of stabilizing handhold equipment image of the present invention shown in Figure 1, comprise step:
101, start sensor;
102, obtain image and rock displacement;
103, convert step 102 gained simulating signal to digital signal through analog-to-digital conversion module;
104, step 103 gained digital signal is sent to the signal digital signal processor processes;
105, step 104 gained signal being sent to central processing unit handles and stores;
106, step 105 gained signal is sent to display driver, through the reference position of display driver control display screen lattice array and scan line;
107, the image display position on the display screen is moved through the adjustment of above-mentioned steps, to keep the relative distance between image and the human eye.
In the device embodiment 1 of stabilizing handhold equipment image of the present invention shown in Figure 2, comprise CPU5, sensor 1, the first analog-to-digital conversion module 2a, the second analog-to-digital conversion module 2b, digital signal processor 4, Asynchronous Serial Interface 3, LCDs driver 7, LCDs 8 and storer 6; Said sensor, analog-to-digital conversion module, Asynchronous Serial Interface, digital signal processor, CPU, display driver and display screen are connected in order; Said storer is connected with CPU.
In the present embodiment, said sensor is a dual spindle gyroscopes, and wherein first of dual spindle gyroscopes connects with said first analog-to-digital conversion module, and second connects with several second analog-to-digital conversion modules of institute.First X component that obtaining image is rocked displacement of said dual spindle gyroscopes converts digital signal to and sends to Asynchronous Serial Interface through first analog-to-digital conversion module; Second Y component that obtaining image is rocked displacement unexpectedly second analog-to-digital conversion module converts digital signal to and sends to Asynchronous Serial Interface; The digital signal of X, Y component sends to digital signal processor, central processing unit and display driver processing back and shows through adjusted image at LCDs after the Asynchronous Serial Interface coupling; Can guarantee that like this relative displacement between human eye and the image fixes; The human eye ciliary muscle is excessively flexible when in rocking environment, seeing handhold equipment image to reduce, thereby slows down human eye vision fatigue.
