When intelligent mobile terminal screen moves forward in z-axis, the video frame images of current broadcasting is carried out amplification process, then the frame of video figure after amplification is presented on the screen of intelligent mobile terminal;

When intelligent mobile terminal screen moves backward in z-axis, the video frame images of current broadcasting is carried out reducing process, then the frame of video figure after reducing is presented on the screen of intelligent mobile terminal;

When intelligent mobile terminal screen is moved to the left in x-axis, by the video frame images of current broadcasting to right translation, then the frame of video figure after translation is presented on the screen of intelligent mobile terminal;

When intelligent mobile terminal screen moves right in x-axis, by the video frame images of current broadcasting to left, then the frame of video figure after translation is presented on the screen of intelligent mobile terminal;

When intelligent mobile terminal screen moves down in y-axis, by the upwards translation of the video frame images of current broadcasting, then the frame of video figure after translation is presented on the screen of intelligent mobile terminal;

When intelligent mobile terminal screen turns clockwise for axle with y direction, by the video frame images of current broadcasting to right translation, then the frame of video figure after translation is presented on the screen of intelligent mobile terminal;

When intelligent mobile terminal screen is rotated counterclockwise for axle with y direction, by the video frame images of current broadcasting to left, then the frame of video figure after translation is presented on the screen of intelligent mobile terminal.

Adopt said method, to a certain extent intelligent mobile terminal screen is used as the eyes of observer, eyes have rotation, mobile and stable ability, therefore the video pictures that mobile phone screen presents can imitate the behavior of eyes, there is initiative to a certain degree, aware space and prevent shake ability, beholder can be felt, and video plane floats below intelligent mobile terminal mobile phone screen, video plane relative to the locus of screen and motor behavior Reality simulation physical world, thus realizes a kind of viewing of feeling of immersion and controls to experience.

For mobile phone, as shown in Figure 1, using video pictures as a plane independent of screen, watch from mobile phone screen, visually this plane is probably positioned at the below of screen.Moving up and down by mobile phone, realizes the Scalable effect of video pictures; By side-to-side movement or the rotation of mobile phone, realize horizontally slipping of video pictures; Moving forward and backward by mobile phone, realizes the slide anteroposterior of video pictures.Mobile phone is described below in detail when playing video file, the processing policy of video pictures:

[video pictures Scalable]

The Scalable degree of video pictures embodies the perceived distance of picture with mobile phone screen, should according to the amplitude of trickle perspective deformation during perceived distance definition skew.In order to ensure practicality, we are using the complete display on the long limit of picture relative screen as being reduced to minimum ratio, consistent with being amplified to maximum ratio with the corresponding screen length of side using the minor face of picture relative screen; For lateral dimension video, as shown in Figure 2, for longitudinal size video, as shown in Figure 3.Detect that mobile phone is the acceleration that vertical direction furthers or zooms out in physical space with screen, just zoom in or out picture, specific implementation needs to get hold of sensitivity.In any case we know rock mobile phone, its speed of finally stopping is 0, namely acceleration a is finally 0 for the integration of time t, therefore the application acceleration degrees of data that we can not be linear carries out Scalable, state machine as shown in Figure 8 can be designed, only using state 1 zooms in or out to acceleration during state 2, substantially disregards or very slight process for from state 2 to the reciprocal acceleration of state 1.

[video pictures translation]

Next we discuss mobile phone translation or rotation, how to affect the position of video pictures in screen, and for convenience of discussing, we first suppose that video pictures amplifies, and are lateral dimension figure, as Fig. 2 left side (longitudinal size is as left in Fig. 3).Although we can calculate the perspective distortion (as Fig. 4) of video pictures according to three dimensions modeling, but we wish the most complete information of video seen, do not wish any distortion, keep feeling of immersion again simultaneously, therefore we it is contemplated that the model of Fig. 5, namely allow video pictures oneself move, mobile phone screen is vertical with the relative angle of viewing eyes forever.If namely mobile phone is in physical space translation, video pictures is in interior of mobile phone translation in the other direction; If mobile phone turns clockwise with the y-axis in Fig. 6 in physical space, video pictures slides to the right, slides left if be rotated counterclockwise video pictures.If slide into the end, still have translation or rotation, then should continue some backgrounds reserving video pictures apart from part of sliding, the strong distance of motion Shaoxing opera (as L in Fig. 7 A) is larger, stop motion rear video picture side back pitch from reverting to 0 (as Fig. 7 B), as there being a kind of innervation bumping against the end.If video pictures narrows down to minimum state (as Fig. 2 is right), also also should should have slight dynamic response to the translation of mobile phone or rotation, as Fig. 7 C, motion Shaoxing opera is strong, responds more obvious.

[video pictures removes shake]

If detect that video pictures has shake, in the opposite direction video pictures is offset (see the 1st frame in Fig. 9) when display video, thus eliminate shake.The scope that setting skew is maximum, real motion is avoided also to be used as shake, there is following method: if the video of previous frame has been be in shifted state, skew present frame simultaneously being detected is still in same direction and offset distance exceedes default maximum magnitude, then offset direction is constant, distance is to maximum magnitude (see the 2nd frame in Fig. 9), and if desired next frame eliminates shake then by normally carrying out toward the skew of other direction.
