For above-mentioned purpose, the feature and advantage that make the application can become apparent more, below in conjunction with the drawings and specific embodiments the application is described in further detail.
The application provides a kind of terminal device that can anti-shake demonstration, and a kind of anti-shake display packing and device, the equipment moving data that provide according to gravity sensor or the gyroscope of mobile device, position, the angle of the dynamic content that movement will show in device screen, the screen of counteracting equipment moves rocking of causing, make the user that the experience of better view content can be arranged, reduce because screen rocks the discomfort impact that brings.
Be elaborated below by embodiment.
With reference to shown in Figure 1, it is the anti-shake display packing process flow diagram of the described a kind of terminal device of the embodiment of the present application.
In the practical application, with the terminal device of gravity sensor, such as accelerometer, or with gyrostatic terminal device, but the motion state of equal monitoring equipment.
Accelerometer has another name called acceleration transducer, is a kind of electronic equipment that can measure accelerating force.Accelerating force is exactly to act on power on the object when object in accelerator, like terrestrial gravitation, and gravity namely.Accelerating force can be a constant, such as g, also can be variable.Acceleration is in respect of two kinds: a kind of is angular accelerometer, and it is a kind of improvement of gyroscope (angular-rate sensor); Another kind is exactly linear accelerometer.
Gyroscope is to utilize the responsive housing relative inertness of the momentum moment space of high-speed rotator around the angular motion monitoring modular of one or two axle that is orthogonal to the axis of rotation.In addition, the angular motion monitoring modular that utilizes other principles to make plays the gyroscope that is also referred to as of said function.
Behind the gravity sensor or gyroscope in the opening device, obtain the current location information of device display area, and the beginning monitoring equipment.Described device display area refers to the zone of displaying contents in the display screen of equipment, and the current location of device display area refers under present case, the position of device display area in screen.
Utilize gravity sensor or gyroscope in the terminal device, can come by following steps the motion state of monitoring equipment:
Come the acceleration of monitoring equipment by the gravity sensor in the equipment or gyroscope, and come the motion state of monitoring equipment by the variation of described acceleration.Wherein, described acceleration can comprise linear acceleration and angular acceleration.
When the acceleration of terminal device changes, show that the motion state of this equipment changes, such as move left and right, mobile, tilted direction moves up and down, turns clockwise or be rotated counterclockwise etc. vertically.
Wherein, if gyroscope, the then angular acceleration of monitoring equipment; If gravity sensor, generally be used for the linear acceleration of monitoring equipment, but also can the monitoring angle acceleration.Comparatively speaking, anti-shake effect can be realized with the terminal device of gravity sensor, best anti-shake effect can be reached with gyrostatic terminal device.
As previously mentioned, shake if terminal device is affected by external force, the acceleration that then can monitor equipment changes, and can show that thus equipment is subjected to displacement, and controls the particular location of the content that shows in the screen this moment by calculating rational parameter.
Need to prove, the displacement that equipment occurs is a kind of relative displacement, for device screen.Because along with the movement of the vehicles such as automobile, train, the observer of equipment and this equipment of use can move, but equipment is static with respect to the observer.So in the time can't keeping relatively static between the screen of beholder's eyes and equipment, just described relative displacement can occur.In other words, described relative displacement refers to the displacement with respect to the generation of plane, original equipment screen place.Further, on two-dimensional space, described relative displacement can comprise the horizontal shift that is parallel to device screen, perpendicular displacement, swing offset.On three dimensions, described relative displacement can be not parallel to the original equipment screen, and an angle can be arranged with the plane at original equipment screen place, and this angle can calculate by gravity sensor or gyroscope monitoring angle accelerometer.
In order to simplify calculating, the below is with the example that is calculated as of two-dimensional space.
Concrete, the displacement information of described computing equipment can be realized by following steps:
According to the acceleration of described equipment and the displacement information of run duration calculating equipment.
For example, adopt gravity sensor or gyroscope can directly obtain accekeration, and then begin to change to the run duration that changes end in conjunction with acceleration, just can calculate the displacement information of equipment.
When equipment occurred level (as about) or vertical (as about) displacement, the displacement information of described equipment comprises level or perpendicular displacement distance, can also comprise the information such as sense of displacement, for example, and the distance that moves to left or move to right etc.Therefore, can be according to the linear acceleration of described equipment and level or the perpendicular displacement distance of run duration calculating equipment.
When equipment rotated displacement, the displacement information of described equipment comprised the anglec of rotation, can also comprise the information such as sense of rotation, for example, and clockwise or angle, the rotation that is rotated counterclockwise and the distance that moves etc.Therefore, can calculate according to the angular acceleration of described equipment and run duration the anglec of rotation of equipment.
More complicated, if the displacement of above-mentioned two kinds of stacks has occured equipment, namely not only level or vertical movement also rotated, then the displacement information of equipment comprises shift length and the anglec of rotation.Wherein, the anglec of rotation can draw according to angular acceleration and the run duration calculating of described equipment, and shift length can draw according to linear acceleration and the run duration calculating of described equipment.
In addition, moving up and down of tilted direction also may occur in equipment, and linear acceleration and the horizontal coordinate x axle of this moment have an angle, and this angle can monitor out by gravity sensor or gyroscope.This moment displacement calculating apart from the time, out linear acceleration of monitoring need to be mapped to respectively on x axial coordinate and the y axial coordinate according to described angle, then calculate respectively the shift length of x axle and y axle according to run duration.Need to prove, the displacement information of equipment also is equivalent to the displacement information of device display area, overlaps because be defaulted as both centers of gravity in the computation process, so calculate the displacement information of equipment, has also namely obtained the displacement information of device display area.
Described renewal position is the equipment position that rear device display area need to revise that shakes, can be by the renewal positional information of following formula computing equipment viewing area:
The renewal positional information of device display area=
The current location information of device display area+
The displacement information of equipment (also being the displacement information of device display area)
Certainly, above-mentioned computing formula is a kind of very simple account form, usually is applicable to level or vertical mobile, if the slightly complicated movement such as rotation also can be calculated by other account forms.And, for level or vertical mobile, also can be realized by other account forms.In a word, the application's protection domain should not be defined in above-mentioned computing formula.
Step 104 is adjusted to described renewal position with device display area from described current location.
Obtain updated space postpone, can carry out by following steps the position correction of device display area:
Adjust the acceleration of device display area according to the acceleration of described equipment, and with the acceleration after this adjustment device display area is moved to described renewal position from described current location.
This move mode by the control acceleration can make the translational speed of device display area press close to the movement of this province of equipment as far as possible, and then reach better anti-shake effect.
Shown in Fig. 2 .1,2.2 and 2.3, be respectively normal condition, state and be rotated counterclockwise under the state schematic diagram that the position of device display area is not yet revised turns clockwise.The boxed area indication equipment viewing area that image wherein, is arranged.

In addition, preferably, above-mentioned device display area is adjusted to the process of described renewal position from described current location, in order to reach better anti-shake display effect, can also be added following limit testing, that is:
In the moving process of device display area, whether the checkout equipment viewing area has moved to outside the screen border, if so, then stops mobile; If not, then continue to move, until move to described renewal position.
Limit testing can prevent that the viewing area from frameing out.Because the position of device display area is in the central authorities of screen, one side but do not want to allow any of viewing area move to outside the screen, so need in the moving process size of viewing area is taken into account.In the practical application, can utilize shift length to check whether current viewing area drops on the inside, border, the left and right sides.
In addition, can also allow in case of necessity a part of displaying contents temporarily move on to outside the screen, guarantee the demonstration output that most contents keeps relative stability, thereby reach anti-shake effect.For this reason, can realize by following steps:
The checkout equipment viewing area moves to the outer part of screen border and whether surpasses preset range, if surpass, thinks that then device display area has moved to outside the screen border; If do not surpass, think that then device display area does not move to outside the screen border.
Described preset range defines the part that displaying contents can move on to outside the screen what is, the screen size of equipment is different, and this preset range is also different.
In sum, the discomfort of having brought when the embodiment of the present application has solved the screen display content of watching mobile device under mobile environment and vision health problem have promoted the experience of evaluation equipment screen under mobile environment.
