Description
Technical field
The present invention relates to stereo display technique field, relate in particular to a kind of high-resolution integration imaging stereo display method and device.
Background technology
Integration imaging display technique is a kind of real tri-dimension display technique.As shown in Figure 1, tradition integration imaging display device is mainly comprised of micro-image primitive array and microlens array, wherein, micro-image primitive array is comprised of a plurality of micro-image primitives, microlens array is comprised of a plurality of lenticules, micro-image primitive is identical with lenticule number, a corresponding lenticule of micro-image primitive.Each lenticule is identical with the pitch of micro-image primitive, and alignment one by one.Shooting process is as shown in Fig. 1 left arrow 11, and 12 pairs of objects 10 of each lenticule are taken from different directions, obtain micro-image primitive 13.Procedure for displaying is the inverse process of shooting process, and as shown in Fig. 1 left arrow 14, the light sending on micro-image primitive 13 is by the refraction of lenticule 12, in the original position reproduction of object object 10 '.
Watching resolution low is a key factor of the integrated imaging technique development of restriction.Because used micro-image primitive array, be equivalent to divide at display device micro-image primitive that a lot of regions shows respectively different visual angles, if used N micro-image primitive, the resolution of each micro-image primitive (total pixel number) is the 1/N of display device, and the resolution of micro-image primitive plays key effect to integration imaging display resolution, so the present common two dimension of the display resolution of integration imaging shows much lower.
