Embodiment
In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearly, understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Embodiment one
Be illustrated in figure 1 the screen anti-fluttering method of a kind of handheld terminal that the embodiment of the present invention provides, the method comprises:
S101, when screen is lighted, the motion state of opening movement Sensor monitoring handheld terminal.
Wherein, motion sensor can be acceleration transducer or gyroscope.
S102, judge whether to detect that handheld terminal is shaken, if so, then perform step S103, otherwise continue monitoring.
Specifically, shake refers to that the central point of screen is greater than 1 millimeter relative to the central point of man-machine interface in horizontal or longitudinal displacement and is less than the wide of screen size or long 50%, that is, compensate for displacement of the present invention carries out within the scope of certain displacement, screen size (as mobile phone and flat screens vary in size) is depended in maximum displacement, be preferable over the half seeing man-machine interface, otherwise displacement too major synchronization point exceed screen ranges and also have little significance.
S103, startup camera are made a video recording and carry out recognition of face, calculate the displacement parameter of face relative to screen.
Preferably, calculate face to comprise relative to the displacement parameter of screen: calculate the transversal displacement of face relative to display screen and the Distance geometry displacement acceleration of length travel and face and screen.
Concrete, foreground image is taken by camera, camera shooting is used when bright and clear, use infrared lamp light to coordinate with infrared camera to take when light is darker, recognition of face (face recognition technology can adopt existing technology, is not described in detail here) is carried out to the image of shooting.But be not simple by image recognition technology to judge displacement, but based on motion sensor data data, further combined with image recognition technology, displacement can be allowed like this to judge faster more accurate.For example, first obtain preliminary exercise data according to displacement transducer, then (be upwards as by face change in location in the picture before and after motion by the contrast of image content, downwards or the change in location in which direction), based on motion sensor data, revise further by image recognition displacement and regulate, the transversal displacement and length travel (i.e. offset data amount) that export final man-machine interface is calculated by the combination of two data, so that follow-up when shift length is in the scope preset, relative to the direction of terminal displacement, reverse bit shift compensation is carried out to man-machine interface.Can also calculate the Distance geometry displacement acceleration of face and screen, zoom in or out so that follow-up man-machine interface, makes image show relative face as far as possible and human eye is in geo-stationary.
S104, according to displacement parameter, the man-machine interface that screen shows to be compensated.
Preferably, this step S104 comprises further: according to transversal displacement and length travel, and the man-machine interface that screen shows is carried out Contrary compensation relative to the moving direction of terminal; Distance geometry acceleration according to face and screen zooms in or out man-machine interface.Particularly, when handheld terminal is not shaken, man-machine interface is positioned at the central authorities of display screen.
When handheld terminal is parallel to face shake to the right, and when producing displacement, man-machine interface moves to the left side of display screen, and concrete mobile range is determined according to the displacement of handheld terminal.
When handheld terminal is parallel to face shake left, man-machine interface moves to the right side of display screen, and concrete mobile range is determined according to the displacement of handheld terminal.
Shake with face when handheld terminal is parallel downwards, and when producing displacement, man-machine interface moves to the upside of display screen, concrete mobile range is determined according to the displacement of handheld terminal.
When handheld terminal is parallel to face shake to upper left, and when producing displacement, man-machine interface moves to the lower left side of display screen, and concrete mobile range is determined according to the displacement of handheld terminal.
When handheld terminal away from or close to face, man-machine interface will present the state of zooming in or out, specifically zoom in or out ratio and acceleration is directly proportional.Specifically, the variation factor exporting and reduce or amplify is calculated according to distance changing value and displacement acceleration changing value, concrete reduce or amplification coefficient (as 10%, 15% or 20%) can provide by experiment, after making convergent-divergent, man-machine interface size is as far as possible identical all the time with original original state man-machine interface size.Such as, retreat 1cm, because distance becomes far away, interface and font are diminished from visual angle, provide an amplification coefficient (such as interface amplifies 10%) according to the variable quantity retreating 1cm, thus make to step back before and after 1cm displacement, relative human eye man-machine interface is as not changing with static.
The screen anti-fluttering method of the handheld terminal of the embodiment of the present invention and device, by introducing face recognition technology, calculate the true relative displacement between face (human eye) and screen, and the true relative displacement between face and screen is considered in screen compensates, to make terminal in certain displacement range, according to displacement parameter, synchronous shift compensation is carried out to the man-machine interface that screen shows, man-machine interface is made to keep static relative to face as far as possible, improve the stability of viewing screen, thus improve user's reading experience.
