1), the 1st group of horizontal microtrabeculae mirror grating state:

(1), the 1st timesharing: the 1st group of strange picture frame of same place, the 2nd group of strange picture frame of same place;

(2), the 2nd timesharing: the 1st group of same place bigraph picture frame, the 2nd group of same place bigraph picture frame;

2), the 2nd group of horizontal microtrabeculae mirror grating state:

(1), the 3rd timesharing: the 3rd group of strange picture frame of same place, the 4th group of strange picture frame of same place;

(2), the 4th timesharing: the 3rd group of same place bigraph picture frame, the 4th group of same place bigraph picture frame.

Because the image demonstration is to scan demonstration from top to bottom, in the one secondary display frame, what top and the bottom showed is not a two field picture, realize to connect and to look and when looking around solid, zone of transition at microtrabeculae mirror grating transition status, microtrabeculae mirror grating and each two field picture segmentation must be made that microtrabeculae mirror grating state is corresponding with two field picture, to avoid occurring cross-interference issue.

When the company of realization looks three-dimensional and looks around solid, each same place picture frame is different relative translation positions with the microtrabeculae mirror grating of different timesharing, the present invention immobilizes microtrabeculae mirror grating, employing divides constantly in difference, and the mode of translation same place picture frame realizes the change with microtrabeculae mirror grating relative position.

A described same place picture frame is the picture frame that a same place of different pixels is formed in the piece image, described strange SD and even SD picture frame and the contrast of described high-definition image frame, and just horizontal definition has reduced half, and vertically clearly constant.

Three-dimensional time-division implementation method is looked around in described pitching, it is characterized in that:

It is made up of with horizontal microtrabeculae mirror grating 2 vertical microtrabeculae mirror grating 1, and vertical microtrabeculae mirror grating 1 makes when changing viewpoint in the horizontal direction, can see the different images of object; Horizontal microtrabeculae mirror grating 2 makes when vertical direction changes viewpoint, can see the different images of object.It can adopt microtrabeculae mirror orthogonal grating preposition or rearmounted, the basically identical of its implementation and the preposition and described microtrabeculae mirror of described microtrabeculae mirror grating grating postposition.

Look around three-dimensional requirement for reaching pitching, the quantity of same place can be 16 or 18 or 24 etc.When the quantity of same place was 24, the same place quantity of horizontal direction can be 6, showed that at twice horizontal definition drops to 1/3, and vertical direction same place quantity is 4, showed that at twice vertical definition drops to 1/2.During 24 same places, take by 24 matrix camera and to obtain 24 same places, 6 cameras of horizontal direction wherein, 4 cameras of vertical direction.This moment, its image display periods was by 4 groups of grating Alternation Display:

(1), Dc group same place picture frame;

(2), Dd group same place picture frame;

(3), Ec group same place picture frame;

(4), Ed group same place picture frame;

(5), Fc group same place picture frame;

(6), Fd group same place picture frame.

Because the image demonstration is to scan demonstration from top to bottom, in the one secondary display frame, what top and the bottom showed is not a two field picture, when realizing that solid is looked around in pitching, zone of transition at microtrabeculae mirror light sieve transition status, microtrabeculae mirror light sieve and each two field picture segmentation must be made that microtrabeculae mirror light sieve state is corresponding with two field picture, to avoid occurring cross-interference issue; Described microtrabeculae mirror light sieve does not carry out displacement, and each parallax point frame of the same name is carried out displacement, makes the two be the relative displacement state, thereby obtains 4 groups of microtrabeculae mirror light sieve relative status.Along with the raising of display refreshing frequency, be expected to improve the sharpness that stereo display is looked around in pitching, when realizing that solid is looked around in the rear-projection pitching, can improve the sharpness that stereo display is looked around in pitching by the quantity that increases projector.
