Description
Technical field
The present invention relates to the field that 3D plays, particularly a kind of 3D plays adaptive method, device and the equipment regulated.
Background technology
3D is the abbreviation of three-dimensional, means three-dimensional graph, and the 3D TV is the abbreviation of 3 D stereoscopic image TV.It is slightly variant that it utilizes people's eyes to observe the angle of object, can distinguish that therefore object is far and near, produces three-dimensional this principle of vision, and the image of seeing right and left eyes separates, thereby makes the user need not can bore hole experience stereo perception by anaglyph spectacles.
The 3D LCD TV is through on liquid crystal panel, adding special accurate cylindrical lens screen; The right and left eyes that the 3D video image that will pass through encoding process is independently sent into the people produces stereoeffect; Can make the user need not can experience stereo perception by anaglyph spectacles, simultaneously can compatible 2D picture.
But; Industry is not carried out standard convention to splicing at present; Connecting method is multifarious; The right left side of the for example parallel splicing in the dual-view left and right sides, dual-view report to the leadship after accomplishing a task splicing, splice, go up down splicing, row splicing, column interleaving splicing, the some splicing etc. that interweaves that interweaves up and down, wherein every kind of splicing also possibly be that full view splices, half height or half-breadth resolution splices, these information are exactly our so-called 3D steric information.Because these information do not have unified standard, cause to play to show whether link can't recognition image be 3D video and 3D video views classification.
Therefore, the user when play showing, according to connecting method again manual work play setting, set and could show correct stereoscopic picture plane after correct, this lets very inconvenience of user.
