Below the present invention is illustrated elaboration.
With regard to hardware implementing, hardware module part of the present invention comprises:
A: collector, as front-facing camera, is positioned at display device the same face, in order to catch the image of user face, gathers the spatial positional information of user's head;
B: display, for showing writings and image information, realizes read function;
C: processor, comprises the various hardware devices of handheld device embedded processing systems, has recognition of face and applies the stabilization computing of self-adaptative adjustment of the present invention.
D: sensor, this sensor is optional module, must not comprise, and is applied to the scene needing to carry out Intelligent adjustment, for the kinematic parameter of Real-time Collection handheld terminal.
Use scenes and use interface are described below:
The use of handheld terminal has the characteristic of movement, in the process of customer location change (movement), uses handheld device to be very common use scenes, as walking, rides public transportation means.For by bus, when vehicle start, due to inertia, passenger can tilt backwards, and then restores to the original state; When jolting in vehicle travel process, passenger can follow downward undulatory motion.In these change procedures, because handheld device forms a loose connection status by human synovial and head, it is a unstable structure.Therefore the motion of head and the motion of handheld terminal are nonsynchronous, understand the difference in life period and amplitude, thus cause the relative motion of handheld device and head, particularly eyes, be called shake here.Even if user is in illegal state, as stood, be seated or lying down, but due to heartbeat and pulse, still can there is the slight jitter relative to head particularly eyes in handheld device.
Read the stabilization that anti-trembling function is mainly used in text importing, but be not limited to word, the information of the static state display such as two dimensional image, three-dimensional image can also be comprised.The relative motion that the present invention causes by compensating above-mentioned reason, reduces and even eliminates shake.
For word, anti-trembling function can make window scheme or screen mode toggle.When using window scheme, window size can arbitrarily regulate.Dynamic tracking and the adjustment of text importing is realized in window ranges.When using screen mode toggle, full screen display scope needs to reduce certain distance, ensures that object content can not exceed screen because of adjustment.
Adjustment aim is divided into multiple: the movement up and down of a two-dimension adjustment realize target.Three-dimensional adjustment except two-dimension adjustment up and down except, also comprise the dynamic change of the adjustment of longitudinal separation and the size of word.Multidimensional adjustment comprises the content of three-dimensional adjustment, and the angle of word different directions rotates.Final purpose be user is felt object content geo-stationary is motionless.
Can realize for menu mode or quick botton mode based on above-mentioned functions application interface.Window scheme is similar to magnifying function, the size that can preset with the mode touched by two fingers or use.Window scheme can effectively reduce the operand of processor module, improves efficiency of algorithm.Screen mode toggle has better user to experience, can not another part does not adjust because of a part of Content adaptation, makes user produce illusion, and disturbs normal reading.
Operating process and effect are described below:
User can open reading anti-trembling function when needs by menu item or button, and selects the complexity that corresponding stabilization adjusts.The stabilization complexity that handheld terminal can be selected according to user carries out corresponding initialization procedure, and points out user to carry out necessary operation.Such as need by equipment just to user, front-facing camera carries out focusing to user's head and face portion and recording image is for subsequent use.
Processor is according to focusing amount and camera parameter, and calculate the distance of user and handheld device, pre-service camera record initialization image data also opens ant-shaking algorithm, adjusts in real time.
For the two-dimension adjustment of window scheme, when handheld device departs to the user left side, then the right side of entirety to handheld device offsets by the content in window and window.When handheld device departs from below user, then the top of entirety to handheld device offsets by the content in window and window.If handheld device is shaken back and forth on display plane direction, then the content in window and window will compensate back and forth along with shake, and user will feel that the content in window and window does not move.
Display area due to handheld terminal is not infinitely great, only occupies a part for user perspective, so when some shake is excessive, the adjustment of processor will make window exceed the scope of display.Therefore the threshold value setting rational window size, the amplitude of each framing control and the amplitude of accumulative adjustment is necessary.So both can ensure the effect of stabilization, again can not because the excessive and hiding portions of display content of shake.
Application scenarios one: two-dimension adjustment (adjustment of displacement), comprises following content:
1, camera Real-time Collection handheld device user head face image and be transferred to processor;
2, processor receives image information, and carries out Digital Image Processing---and the head and face profile in image is separated, sets up the two dimensional model of abstract shapes (round, oval or rectangle is stepped on), to determine the center position coordinate of this shape.Coordinate origin adopts the center of camera viewfinder range.
3, the center point coordinate position obtained after the model center point coordinate collected and upper piece image process compares and calculates displacement vector by processor.
4, the offset that adjusts according to the distance value of the displacement vector values of user's head, user and equipment, the average eyeball parameter of targeted customer and user of processor, calculates the side-play amount of target area.
Wherein, the offset of user's adjustment is option, not necessarily.
5, processor adjusts the position of the content of display device target area according to the side-play amount of target area and outputs to display.
Wherein the adjustable offset of user needs user to set before use, if not setting, does not compensate.Namely calculate according to mean parameter.The setting compensated can after startup anti-trembling function, and user moves up and down handheld device, and according to sensation adjustment compensation rate, until window is not mobile with the movement of handheld device.Method of operating can be that scroll bar mode is waved in numerical value adjustment.
Application scenarios two: distance adjustment, comprises following content:
1, camera Real-time Collection handheld device user head face image and be transferred to processor module;
2, processor receives image information, and carries out Digital Image Processing, sets up abstract two dimensional model, calculates the area when the first two bit model.
3, the area that area and the last image procossing when the first two bit model obtains compares by processor, draws the ratio of area change, represents with number percent.
4, the offset that adjusts according to the distance value of user's head area change, user and equipment, average eyeball parameter and user of processor, calculates the adjustment amount of target area size.Described adjustment amount refers to for the follow-up place-centric obtained, and based on this place-centric, target area is zoomed in or out how many times.
Wherein, the offset of user's adjustment is option, not necessarily.
