Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, the present invention is described in further detail.
As mentioned above, under some application scenarios, spectators do not expect to occur the 3D video pictures, but expectation realizes that different spectators watch different video contents by same complete screen.
Such as: in the double fight of game machine, expect that different game players can watch different game pictures by same screen.Suppose that two game players are playing double fight game, be respectively player A and player B, player A wishes to watch by screen the game picture of player A, and player B wishes to watch by this same screen the game picture of player B.
At present, the method that in prior art, general employing screen is cut apart attempts addressing this problem.Fight that both sides divide although the zones of different of same screen (such as: at the game picture that district shows the player that parts on the left side of screen, at the game picture that district shows player B that parts on the right side of screen) fight operation.This mode has divided screen, and each player can only watch half screen, so the game video display effect is lower, and because the player can watch other player's screen, so also the own normal fair operation of playing has been caused to interference.
Particularly, Fig. 1 is that in prior art, game player's sub-screen shows schematic diagram.As shown in Figure 1, present respectively two players' game picture by the zone up and down of same screen, each player can only see half screen, and each player can see other player's game picture, the risk that therefore also may exist game to swindle.
In fact, not only in the double fight of game, the problems referred to above may occur, under other application scenarios, may occur that too different spectators expect to watch by same complete screen the situation of different video content.
Such as: suppose that a pair of man and wife is in and see TV, the husband is the sports enthusiast, and sports channel is seen in expectation, and wife is the soap opera fan, channel for TV plays and movies is seen in expectation, man and wife two people now just occurred how solving and has watched the technical problem of different content of TV program by same screen.
For above-mentioned technical problem, embodiment of the present invention has proposed a kind of video picture displaying method.
Fig. 2 is the video picture displaying method flow chart according to embodiment of the present invention.
As shown in Figure 2, the method comprises:
