Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those skilled in the art obtain belongs to the scope of protection of the invention.
Seeing also accompanying drawing 1, is the image flow for displaying synoptic diagram that the embodiment of the invention provides, and mainly comprises step S101, step S102 and step S103, particularly:
S101 obtains the current attitude coordinate of terminal.
In one embodiment of the invention, can obtain terminal under current attitude, detect the calculation of parameter that obtains by Gravity accelerometer, angular-rate sensor and magnetic field sensor and obtain the current attitude coordinate of described terminal.Particularly, terminal (for example, smart mobile phone etc.) built-in hardware sensor, for example, a kind of or its combination in any wherein such as acceleration transducer, angular-rate sensor or magnetic field sensor can obtain by Real-Time Monitoring some parameters of terminal, such as acceleration etc., and the parameter of these Real-time Obtainings passed to CPU (central processing unit) (Central Processing Unit, CPU).CPU uses default function calculation to obtain the current attitude coordinate of terminal according to these parameters, and this attitude coordinate is used for describing described attitude at three dimensions.For convenience, in the following description, the attitude coordinate of terminal can be used three-dimensional coordinate (X, Y, Z) expression, wherein, X represents the coordinate of vertical direction, and Y and Z represent the coordinate of plane (XY plane) direction.
As preferred embodiment a kind of, the equal usage space vectorial coordinate of attitude coordinate in the present embodiment, and in three-dimensional reference frame, take perpendicular to the direction in the earth's core as Z axis, two orthogonal directions that are parallel to surface level are respectively X-axis and Y-axis.
S102 obtains the new coordinate of each point of described image according to the coordinate of each point of attitude Coordinate Adjusting image.In embodiments of the present invention, because image always is presented on the display screen of terminal, and image is comprised of a plurality of points (pixel), therefore, in case the current attitude coordinate of terminal self is determined, then according to the coordinate time of each point of attitude Coordinate Adjusting image, the difference of the attitude coordinate that the coordinate of image is current with respect to terminal is a relatively constant value function relation, and is for example zero.So, three-dimensional coordinate (X under the acquisition terminal is arbitrarily angled, Y, Z) time, image is in fact just according to identical with the current attitude of terminal or (for example show with the attitude of a relative deviation, no matter how terminal puts, and certain three-dimensional plot target front makes progress always), be not limited to just 90 ° and 180 ° of two kinds of angles and show.
S103 shows image according to new coordinate in terminal.
When the primary processor of terminal sent corresponding display command with the new coordinate of image as display parameter, display module showed take new coordinate as parameter this image on display screen.
