Below by taking display device is mobile phone as an example, the working method of the display device of the present invention is carried out in conjunction with attached drawing detailed
It introduces：
In the present embodiment, mobile phone includes that (CPU specifically may be used in high speed camera, infrared distance measurement module, processing module
To realize), acceleration transducer, wherein acceleration transducer on mobile phone for judging whether fast vibration scene generates,
When the acceleration for the mobile phone that acceleration transducer detects is greater than the set value, it can be determined that mobile phone is in fast vibration scene.
High speed camera is for judging whether user is used mobile phone under the scene of fast vibration, high if mobile phone is used
Fast camera meeting real-time capture user portrait, and its eye feature is extracted, meet at processing module analyzing processing.Processing module is used for
The eye feature of the user under fast vibration scene is compared, analysis calculates absolute displacement of the mobile phone relative to user's eye feature,
The deviant of picture shown by mobile phone is calculated according to mobile phone pel spacing.
As shown in figure 3, the working method of the mobile phone of the present embodiment specifically includes following steps：
Step 1：Mobile phone initializes, and in this step, the eye that can pre-deposit user compares feature.
Step 2：The acceleration value of the acceleration transducer detection mobile phone of mobile phone, when the acceleration value ＞ setting values detected
Or the quick speed change of acceleration, illustrate that mobile phone is in vibration and shows scene, then opens high speed camera, otherwise closing high-speed images
Head.
Step 3:High speed camera captures the real-time portrait of user, and compares characteristic matching with the eye to prestore, wherein in advance
It can be that eyes image when user watches mobile phone determines that user is used if successful match that the eye deposited, which compares feature,
Mobile phone, Fig. 4 show mobile phone vibration interval diagram, wherein 1 is mobile phone, 2 be display screen, and 21 be the figure shown on screen
Mark.
Step 4:Determine that user's eye feature point is analyzed relative to high speed camera in mobile phone display area, processing module in real time
The relative position of picture is shot, and determines the location information of mobile phone display area.It is illustrated in figure 5 the aobvious of the display screen of mobile phone
Show interval diagram, when user watches mobile phone and mobile phone does not vibrate, it is believed that the eye feature point face of user shows screen
Center.
Step 5:Calculate pixel offset value and offset direction that mobile phone shows picture.Processing module analyzes high-speed camera in real time
Head shooting portrait, calculates number of pixels and the offset direction of the eye feature point offset of user, and the display picture of mobile phone is to phase
The same number of pixels of equidirectional offset, it is vacant to go out to mend black picture.
The display picture view being illustrated in figure 7 before picture offset, Fig. 8 are the schematic diagram for showing picture and deviating to the right,
Fig. 9 is the schematic diagram for showing picture and deviating to the left.
As shown in fig. 6, when calculating the pixel offset value of eye feature point of user, it can be with plane where user's face
A coordinate section is established, the coordinate section and mobile phone display screen curtain parallel and symmetrical, the range in the coordinate section are equal to mobile phone
It shows screen, calculates the eye feature that pixel offset value of the eye feature point of user on the coordinate section can be obtained user
The pixel offset value of the display screen of the opposite mobile phone of point, namely obtain the value that the display picture of mobile phone should deviate.
As shown in fig. 6, the horizontal view angle of the eye feature point of mobile phone camera shooting user is a, vertical angle of view b, hand
The horizontal pixel spacing of the display screen of machine is PH, and vertical pixel spacing is PV, then in the coordinate section, horizontal pixel spacing
Also it is PH, vertical pixel spacing is also PV, and mobile phone display screen curtain hanging down apart from eye feature point is measured using infrared distance measurement module
Straight distance is h, then the vertical range in the coordinate section to camera is also h, and the length and width of the display screen of mobile phone are respectively A and B,
Then the coordinate section maximum abscissa is A, and maximum column coordinate is B.
Under original state, camera is opposite with the eye feature of user point, and the eye feature point of user is located at the coordinate area
Between central point, the coordinate of the eye feature point of user in the coordinate section is (x1, y1), correspondingly, mobile phone display screen curtain
Centre coordinate is also (x1, y1), and after mobile phone vibration, the coordinate of the eye feature point of user in the coordinate section is (x2, y2), phase
The coordinate of Ying Di, the orthographic projection of the eye feature point of user on mobile phone display screen curtain are also (x2, y2), can be according to above-mentioned ginseng
Number calculates the value of lateral displacement SH of the eye feature point of user：According to (x2-x1)/(A-x1)=SH/h*tan (a/2), SH is obtained
=(x2-x1) * h*tan (a/2)/(A-x1)；
The length travel value SV for calculating the eye feature point of user, according to (y2-y1)/(B-y1)=SV/h*tan (b/2),
Obtain SV=(x2-x1) * h*tan (b/2)/(B-y1).
Then calculate mobile phone horizontal pixel offset：Pixel_x=SH/PH, mobile phone vertical pixel offset：Pixel_y=
SV/PV。
Show picture according to horizontal pixel offset and vertical pixel offset into line displacement later, you can so that display screen
Curtain is showing picture with user's relatively fixed position, can effectively solve user and watch the display device of fast vibration to bring
Dizziness problem.
