Amplification coefficient resolution unit 212 reduces by half to generate horizontal amplification coefficient kx and vertical amplification coefficient ky in the horizontal direction or in vertical direction according to the resolution of the right and left eyes view after the parallax dx of input, fractionation.Suppose that full resolution (resolution before 3D rendering does not split) is for W*H(W row pixel, the capable pixel of H), when the right and left eyes view being split is when resolution reduces by half in the horizontal direction, the relational expression of kx and ky and dx and W is suc as formula shown in (1):
When the right and left eyes view being split is when resolution reduces by half in vertical direction, the relational expression of kx and ky and dx and W as the formula (2):
The amplification coefficient resolution unit 212 horizontal amplification coefficient kx of output and vertical amplification coefficient ky be to the depth of field adjustment unit 24 adjusting depth of field, and meanwhile, this amplification coefficient resolution unit 212 is also exported parallax dx and depth of field change information to depth of field adjustment unit 24.
The concrete structure of depth of field adjustment unit 24 and with the annexation of other parts as shown in Figure 4.This depth of field adjustment unit 24 comprises image amplifying unit 241, interception unit 243 and the 3rd memory 242.Image amplifying unit 241 receives from amplification coefficient kx and the ky of amplification coefficient resolution unit 212 and comes from first memory 224 and left-eye view and the right-eye view of second memory 225 storages, and two views are amplified by amplification coefficient kx and ky, the left-eye view after amplification and right-eye view are stored in the 3rd memory 242.Right and left eyes view after amplification, is greater than a screen dx pixel in the horizontal direction, and resolution becomes (W+dx) * H, the parallax of dx for adjusting.
Interception unit 243 is according to the parallax dx of amplification coefficient resolution unit 212 outputs, and the type of the stereoeffect of depth of field variable quantity and MCU23 output intercepts the view data being exaggerated in the 3rd memory 242.Then the right and left eyes view of intercepting is served to screen 40 through this output unit 30.
Intercepting is that the depth of field regulates pith, below the process that interception unit 243 is implemented to image interception is described in detail.
The formation principle of paper stereoeffect, as shown in Figure 5, stereoeffect has depression and protrudes these two types, L represents left-eye view, and R represents right-eye view, when the left side of L at R, observer's eyes are observed the sight line intersection point of L and R at screen rear, and stereoscopic picture plane presents depression effect; When L the right at R, observer's eyes are observed the sight line intersection point of L and R in screen the place ahead, and stereoscopic picture plane presents depression effect.
The method that the depth of field regulates is exactly the parallax that will regulate right and left eyes view, and its basic principle as shown in Figure 6.When depression situation, when R moves to R ', L and R, apart from becoming far away, represent that parallax increases, and sight line watches the intersection point of L and R also to become away from screen, and such depression effect is more obvious, and the depth of field is larger; When the left side of R at L, the situation of little parallax (protruding), i.e. the protrusion situation of stereoscopic picture plane, the little depth of field shown in figure (protruding); L and R are far away, the situation of large parallax (protruding), and parallax strengthens, and protrudes situation more obvious, occurs the result of the large depth of field (protruding) in figure.Generally speaking, parallax strengthens the depth of field and strengthens, and parallax reduces the depth of field and reduces.
