Description
Technical field
The present invention relates to Display Technique, particularly a kind of signal processing method and device.
Background technology
At present, the naked 3 d display device of looking is also in conceptual phase, universal in a large number, and due to the naked restriction of looking Display Technique and signal processing technology, makes nakedly depending on 3 d display device, to fail perfection.
At present, three-dimensional (3D) auto-stereoscopic display of bore hole of developing based on binocular parallax is mainly raster pattern 3D auto-stereoscopic display.It is in 2D flat-panel screens, to install grating additional to form.Grating can be divided into cylindrical grating or slit grating, and cylindrical grating is called again cylindrical lens raster or lenticular sheet, and slit grating is called again looks barrier baffle plate or slotted barrier.Utilize the principle of grating beam splitting, the light that the pixel of display screen zones of different is sent distinguishes.
Conventionally, the naked every two field picture depending on showing in display device of N viewpoint, it is N viewpoint view sequence, to play up and form by the individual subgraph with certain parallax composition of N, wherein each subgraph obtains by the video camera of diverse location respectively, or the video camera of simulation diverse location obtains by concrete algorithm is synthetic.According to the quantity of video camera and position, when showing N viewpoint view sequence on display floater, can be divided into P display unit according to the setting of grating, each display unit comprises N sub-set of pixels.As shown in Figure 1A, the sub-pixel collection in each display unit from right to left, the 1st sub-set of pixels of called after successively, the 2nd sub-set of pixels, the 3rd sub-set of pixels ..., N sub-set of pixels, can be followed successively by it and be numbered 1,2,3 ... N.When showing the naked view image signal of N viewpoint, represent respectively N subgraph corresponding sub-pixel collection in this display unit that video camera obtains from left to right.The sub-pixel collection of this N viewpoint view sequence is arranged respectively demonstration on display floater, only shows the one-row pixels of described display floater in Figure 1A.In the display unit of P wherein, the sub-pixel collection of all called afters 1 forms the first subgraph, and the sub-pixel collection of corresponding all called after i forms i subgraph.A in Figure 1A represents grating.
Through minute light action of grating, in watching space, in a vision area unit, spectators' right eye can be seen i subgraph, and left eye can be seen i-1 subgraph.
In present technology, i subgraph and i-1 subgraph have the positive parallax of a times, and i subgraph and i-1 subgraph are respectively adjacent two video cameras in right side, left side and obtain image, and i subgraph enters user's right eye, and i-1 subgraph enters user's left eye.User sees two images with positive parallax, thereby obtains correct stereos copic viewing effect.At this moment we claim between sub-pixel collection i and i-1, to have the positive parallax of a times.
But at two adjacent vision area unit intersections, user's left eye is seen N subgraph, right eye is seen the 1st subgraph, due to from the 1st subgraph to N subgraph, two adjacent subgraphs all have positive parallax, and it is large that parallax composition becomes gradually, at this moment, the 1st subgraph of adjacent vision area and N subgraph have formed 1-N positive parallax doubly, i.e. N-1 contrary parallax doubly, and left eye is seen the subgraph of right side video camera acquisition, right eye is seen the subgraph that left side camera obtains, and is called contrary vision area.If N is larger, in general, if N is not less than 4, user, when against vision area, can affect viewing effect, may also can make user produce sense of discomfort, for example may produce serious spinning sensation, also reduced display effect, user cannot normally be watched.
And for the excessive problem of parallax between the contrary adjacent subgraph of vision area, there is no good solution in prior art.

A signal processing method, said method comprising the steps of:
Obtain original image information, described original image information at least comprises piece image;
According to described original image information, obtain benchmark image information and N viewpoint view sequence depth information;
According to described benchmark image information and described N viewpoint view sequence depth information, obtain N viewpoint view sequence; In described N viewpoint view sequence, include H display unit, wherein in each display unit, include N sub-set of pixels; Wherein, in described N sub-set of pixels, by dextrosinistral order, a sub-set of pixels from the 2nd sub-set of pixels to i, parallax between each sub-pixel collection and the 1st sub-set of pixels forms increasing sequence, and from i sub-set of pixels to N sub-set of pixels, the parallax between each sub-pixel collection and the 1st sub-set of pixels forms descending series, i is positive integer, and i is for being not less than
and be not more than the integer of N-1.
Wherein, actual is that the pixel of the image below each lens pillar is divided into several sub-pixel collection, lens pillar just can be with each sub-pixel collection of different direction projections like this, so eyes are watched display screen from different angles, just see different sub-pixel collection, parallax in the embodiment of the present invention between said sub-pixel collection, actual refer to is when user sees the sub-pixel collection through lens projects, two adjacent one of sub-set of pixels enter user's left eye, and another enters user's right eye (in other words, corresponding one adjacent of two subgraph of two adjacent sub-set of pixels enter user's left eye, and another enters user's right eye), therefore the parallax producing between user's right and left eyes.That is, the parallax in the embodiment of the present invention is the vision area unit of seeing for user, and not for display unit.

Optionally, when described original image information is 2D picture signal, can obtain described N viewpoint view sequence depth information according to described original image information, can be according to the grating feature of corresponding display unit and corresponding naked video element permutation algorithm, take described original image information as reference, and therefrom first extract benchmark 3D subgraph in N viewpoint.On the basis of this benchmark 3D subgraph extracting, can determine by described N viewpoint view sequence depth information the content of the sub-pixel collection of all the other 3D subgraphs.
Optionally, when first obtain be two-way 3D rendering signal time, can obtain according to depth extraction algorithm the described N viewpoint view sequence depth information of two-way 3D rendering signal, and can in the wherein road picture signal from two-way 3D rendering signal, extract benchmark 3D subgraph, i.e. benchmark image information.
Optionally, if described original image information is 3D rendering signal, and described original image information is while being the naked view image signal of N viewpoint, can from described original image signal, extract 2D picture signal, using the 2D picture signal extracting as benchmark image information.And, obtain N viewpoint view sequence depth signal.Wherein, when obtaining described N viewpoint view sequence depth signal, can generate with reference to the content between each subgraph in described original image signal.Extracting described benchmark image information and generating after described N viewpoint view sequence depth information, can synthesize the 3D subgraph of each viewpoint in N viewpoint according to described benchmark image information and described N viewpoint view sequence depth information, thereby can obtain N viewpoint view sequence.
Step 103: obtain N viewpoint view sequence according to described original image information and described N viewpoint view sequence depth information; In described N viewpoint view sequence, include H display unit, wherein in each display unit, include N sub-set of pixels; Wherein, in described N sub-set of pixels, a sub-set of pixels from the 2nd sub-set of pixels to i, parallax between each sub-pixel collection and the 1st sub-set of pixels forms increasing sequence, from i sub-set of pixels to N sub-set of pixels, parallax between each sub-pixel collection and the 1st sub-set of pixels forms descending series, and i is positive integer, and i is for being not less than
and be not more than the integer of N-1.
Wherein, actual is that the pixel of the image below each lens pillar is divided into several sub-pixel collection, lens pillar just can be with each sub-pixel collection of different direction projections like this, so eyes are watched display screen from different angles, just see different sub-pixel collection, parallax in the embodiment of the present invention between said sub-pixel collection, actual refer to is when user sees the sub-pixel collection through lens projects, two adjacent one of sub-set of pixels enter user's left eye, and another enters user's right eye (in other words, corresponding one adjacent of two subgraph of two adjacent sub-set of pixels enter user's left eye, and another enters user's right eye), therefore the parallax producing between user's right and left eyes.That is, the parallax in the embodiment of the present invention is the vision area unit of seeing for user, and not for display unit.
For example, for the described N in a display unit sub-set of pixels, by dextrosinistral order, a sub-set of pixels from described the 2nd sub-set of pixels to described i, between each sub-pixel collection and described the 1st sub-set of pixels, after grating projection, may be that described i sub-set of pixels enters user's right eye, and adjacent previous sub-pixel collection i-1 enters user's left eye, (subgraph that the sub-pixel set pair on the right is answered in other words conj.or perhaps enters user's left eye, and the subgraph that the sub-pixel set pair on the adjacent left side is answered enters user's right eye), now, the sub-pixel collection on the right comes from the video camera that is positioned at the left side, the sub-pixel collection on the left side comes from the video camera that is positioned at the right, therefore, a sub-set of pixels from described the 2nd sub-set of pixels to described i, user sees two images with positive parallax, thereby what obtain is correct stereos copic viewing effect.Due to a sub-set of pixels from the 1st sub-set of pixels to i, the sub-pixel collection on each left side parallax composition with respect to the sub-pixel collection on the right being adjacent becomes large, therefore, a sub-set of pixels from described the 2nd sub-set of pixels to described i, between each sub-pixel collection and described the 1st sub-set of pixels, formed parallax can form an increasing sequence.
For example, for the described N in a display unit sub-set of pixels, by dextrosinistral order, from described i sub-set of pixels to described N sub-set of pixels, between each sub-pixel collection and the previous sub-pixel collection that is adjacent (for example, between N sub-set of pixels and N-1 sub-set of pixels, between N-1 and sub-pixel collection and N-2 sub-set of pixels, ..., between i+1 sub-set of pixels and i sub-set of pixels), after grating projection, the sub-pixel collection on the right enters user's left eye, and the sub-pixel collection on the adjacent left side enters user's right eye, for example, may be that described i+1 sub-set of pixels enters user's right eye, and described i sub-set of pixels enters user's left eye.And now, because the sub-pixel collection on the right comes from the video camera that is positioned at the right, the sub-pixel collection on the left side comes from the video camera that is positioned at the left side, therefore, what user saw is two images with contrary parallax.
Due to a sub-set of pixels from i sub-set of pixels to N, the sub-pixel collection on each the right diminishes with the parallax composition of the 1st sub-set of pixels with respect to the sub-pixel collection on the left side being adjacent, therefore, from described i sub-set of pixels to described N sub-set of pixels, between each sub-pixel collection and described the 1st sub-set of pixels, formed parallax can form a descending series.
And for two adjacent sub-set of pixels of adjacent display cell, after grating projection, the rightmost sub-pixel collection that is positioned at the display unit on the left side enters user's right eye, the leftmost sub-pixel collection that is positioned at the display unit on the right enters user's left eye, and now, the rightmost sub-pixel collection that is positioned at the display unit on the left side comes from the video camera on the left side, the leftmost sub-pixel collection that is positioned at the display unit on the right comes from the video camera on the right, therefore, what user saw is two images with contrary parallax, and the contrary parallax forming between the adjacent subgraph of adjacent vision area is larger.Like this, when N is more than or equal to 4, reach 3 times of above contrary parallaxes, will cause user to produce great spinning sensation.
