Refer to the schematic flow sheet that Fig. 1, Fig. 1 are 3D signal cutting method first embodiments of the present invention.

The described 3D signal cutting method of present embodiment comprises the following steps:

Step S101, the resolution of acquisition input signal and the unit coordinate of display unit and intrinsic resolution.

Step S102, according to pre-set shear parameter rule, by described resolution, described unit coordinate and described Intrinsic resolution is converted to the left-eye image shear parameters of described display unit；Described left-eye image shear parameters Including left eye horizontal shear original position, left eye horizontal shear length, left eye vertical shear original position and a left side Eye vertical shear height.

Step S103, identifies the signal format of described input signal.

Step S104, by described left eye horizontal shear original position and described left eye vertical shear original position, Carry out position translation according to the translation parameters corresponding to the signal format identified, generate eye image shear parameters In right eye horizontal shear original position and right eye vertical shear original position.

Step S105 is respectively according to described left-eye image shear parameters and described eye image shear parameters, right Described input signal is sheared, and generates left eye shear signal and the right eye shear signal of each display unit； Right eye horizontal shear length in described right eye shear parameters and right eye vertical shear height respectively with described left eye Horizontal shear length is put identical with described left eye vertical shear height.

Present embodiment, by the resolution of input signal and the unit coordinate of display unit and intrinsic resolution Be converted to the left-eye image shear parameters of described display unit；Identify the signal format of described input signal again； By described left eye horizontal shear original position and described left eye vertical shear original position, according to the signal identified Translation parameters corresponding to form carries out position translation, and the right eye level generated in eye image shear parameters is cut Cut original position and right eye vertical shear original position；Finally according to described left-eye image shear parameters and described Eye image shear parameters, shears described input signal, and the left eye generating each display unit is sheared Signal and right eye shear signal.The shearing of 3D signal can be realized rapidly and accurately, for windowing on a display screen Shear signal is provided.

Wherein, for step S101, the resolution of described input signal preferably includes horizontal resolution and hangs down Straight resolution.The unit coordinate of display unit preferably can include horizontal origin coordinates, horizontal width, vertical Origin coordinates and vertical height.Described intrinsic resolution preferably can include intrinsic horizontal resolution and intrinsic hang down Straight resolution.

In one embodiment, system coordinates is with the upper left corner of whole display system upper left corner unit as coordinate Initial point, is to the right horizontal coordinate (X) axle positive direction, is downwards vertical coordinate (Y) axle positive direction.Unit Coordinate is with the upper left corner of each display unit as zero, is to the right horizontal coordinate (X) axle positive direction, It is vertical coordinate (Y) axle positive direction downwards.Owing to window can be opened in this unit, it is also possible to not at this unit, So horizontal coordinate and vertical coordinate can the most also can be born in unit coordinate.

Preferably, can be according to the unit coordinate of above-mentioned coordinate Rule display unit.

For step S102, signal is entered by described pre-set shear parameter rule preferably 2D fenestration procedure The algorithmic rule that row is sheared.

Preferably, as in figure 2 it is shown, mosaic display screen includes 0-0 display unit, 0-1 display unit, 1-0 Display unit and 1-1 display unit, leave the 3D window at display screen, has only to display for 0-0 display unit Signal upper left hand corner section, other positions need not, and 1-0 display unit has only to the lower left corner part of entire image, Other display units have only to the content specifying position of whole image, if it is incorrect to shear content, The last width that just cannot be spliced into shows picture.Clip image can define by four parameters: horizontal shear rises Beginning position, horizontal shear length, vertical shear original position, vertical shear height.

In one embodiment, left-eye image shear parameters and the window display parameter of each display unit are as follows Shown in:

The unit coordinate of display unit includes horizontal origin coordinates SignalWindow [i] .StartX, horizontal width SignalWindow [i] .Width, vertical origin coordinates SignalWindow [i] .StartY and vertical height SignalWindow[i].High。

Image cut parameter includes horizontal shear original position SignalAxis.StartXoffset, horizontal shear width SignalAxis.Width, vertical shear original position SignalAxis.StartYoffset and vertical shear height SignalAxis.High。

Image display parameters includes that window shows horizontal original position WindowAxis.StartX, window display width Degree WindowAxis.Width, window display vertical starting position WindowAxis.StartY and window display height Degree WindowAxis.High.

The intrinsic resolution of display unit includes intrinsic horizontal resolution WindowHor and intrinsic vertical resolution WindowVer。

The horizontal resolution of the resolution (resolution of the signal of window interior needs display) of input signal is SinnalHor, vertical resolution is SinnalVer.

Horizontal scaling coefficient WidthFlag is the ratio of SignalWindow [i] .Width Yu SinnalHor, hangs down Straight zoom factor HighFlag is the ratio of SignalWindow [i] .High Yu SinnalVer.

The rule obtaining the image cut parameter of each display unit and window display parameter is as follows:

One, the trunnion axis X-coordinate of display unit is timing: the starting point of display window and rising of unit coordinate SignalWindow [i] .StartX of initial point is identical.The start bit set 0 (Far Left of image) of clip image, Situation in two below image cut length gauge point counting:

1, X-direction window is not across screen:

During as it is shown on figure 3, window is not across screen, in 0-0 display unit, window lateral length is not above level admittedly There is resolution (i.e. SignalWindow [i] .StartX+SignalWindow [i] .Width≤WindowHor). So width of display window is equal to width (the i.e. WindowAxis.Width=of unit coordinate SignalWindow[i].Width).Image level shows all images on direction, therefore image cut width etc. Horizontal resolution (i.e. SignalAxis.Width=SinnalHor) in signal.

2, X-direction window is across screen:

As shown in Figure 4, window is when screen, and display unit 0-0 only shows a part for image, needs display Lateral length is less than width (i.e. SignalWindow [i] .StartX+ of unit coordinate SignalWindow[i].Width>WindowHor).Now window display width subtracts equal to display screen natural width Remove unit origin coordinates (i.e. WindowAxis.Width=WindowHor-SignalWindow [i] .StartX), The ratio that image cut width then accounts for SignalWindow [i] .Width according to WindowAxis.Width is counted Calculate.SinnalHor pixel to be put in SignalWindow [i] .Width, then the horizontal shear width of image Degree is: SignalAxis.Width be multiplied by WindowAxis.Width be multiplied by SinnalHor again divided by SignalWindow [i] .Width, i.e. horizontal scaling coefficient.

Two, the trunnion axis X-coordinate of display unit is for time negative: as shown in Figure 4, for 0-1 display unit and 1-1 display unit, the unit coordinate X of 0-1 display unit and 1-1 display unit is negative, mono-with 0-1 As a example by unit, the parameter in horizontal direction is calculated as follows:

Owing to display is from the beginning of 0 coordinate, so the original position of display window is 0, i.e. WindowAxis.StartX=0, the original position of image cut is not 0, it should eliminate the figure in 0-0 unit Picture, for 0-1 unit, the original position of image cut should be just that the shearing width of 0-0 unit adds 1, For 0-1 unit, the value of SignalWindow [i] .StartX is equal to the WindowAxis.Width of 0-0 unit, The shearing original position i.e. SignalAxis.StartXoffset=of 0-1 unit | SignalWindow [i] .StartX |/WidthFlag)+0.5, wherein SignalWindow [i] .StartX&0x7fff is that sign bit is removed, and adds 0.5 It is in order to parameter is rounded.

It is below two kinds of calculated level sheared lengths and the method for level display length:

3, X-direction window is not across screen:

Owing to not having across screen in 0-1 display unit horizontal direction, window display width is equal to the water of unit coordinate Flat width deducts horizontal origin coordinates, i.e. WindowAxis.Width=SignalWindow [i] .Width- (SignalWindow[i].StartX&0x7fff).Image level shearing width ibid, can be according to ratio by window Width obtains divided by zoom factor.That is: SignalAxis.Width =WindowAxis.Width/WidthFlag+0.5.

4, X-direction window is across screen:

As it is shown in figure 5,0-1 display unit is in the horizontal direction across screen to 0-2 display unit, now window Display width WindowAxis.Width is equal to the intrinsic resolution in the horizontal direction of display WindowHor, image level shearing width i.e. WindowHor are divided by zoom factor.I.e. SignalAxis.Width=WindowHor/WidthFlag.

Three, the vertical axis Y coordinate of display unit is timing: as shown in Figure 4, for 0-0 display unit, Y Coordinate on direction is just, the original position of resize-window is equal to the original position of unit coordinate i.e. WindowAxis.StartY=SignalWindow [i] .StartY, the original position that signal Y-direction is sheared is 0 I.e. SignalAxis.StartYoffset=0.

5, when in Y-direction, window is not across screen:

As shown in Figure 6, in Y-direction, the height sum of the original position of display window and display window is less than or equal to The intrinsic resolution of display unit vertical direction i.e. SignalWindow [i] .StartY+ SignalWindow [i] .High)≤WindowVer, at this moment window shows and is highly equal to the vertical of display unit Highly (WindowAxis.High=SignalWindow [i] .High).Image cut height is equal to inside image The vertical resolution divided, i.e. SignalAxis.High=SinnalVer.

6, in Y-direction window across screen time:

As shown in Figure 4, Y-direction needing across screen, now window display height is vertical equal to 0-0 display unit Direction intrinsic resolution deducts the original position of display unit Y, i.e. WindowAxis.High=WindowVer -SignalWindow [i] .StartY, the image in image Y-direction is only with a display part, its image cut height Spend the ratio calculating accounting for whole display height according to 0-0 display unit, i.e. SignalAxis.High =WindowAxis.High/HighFlag, SignalAxis.High=WindowAxis.High*SinnalVer/ SignalWindow[i].High/SinnalVer。

Four, the vertical axis Y coordinate of display unit is for time negative:

7, when in Y-direction, window is not across screen: as shown in Figure 4, for 1-0 display unit, Y rises Beginning coordinate is negative value, calculates the shearing zoom factor of 1-0 display unit below.Window shows horizontal original position Be 0, i.e. WindowAxis.StartY=0, image cut vertical starting position adds equal to the height of a upper unit 1, the height that upper unit the is sheared original position equal to unit coordinate Y is divided by zoom factor.I.e. SignalAxis.StartYoffset=| SignalWindow [i] .StartY |/HighFlag+0.5.Window display height etc. In the height of unit coordinate, i.e. WindowAxis.Width=WindowHor.Image vertical shear height is pressed In this unit, scaling window height accounts for the ratio calculating of whole display window height, i.e. SignalAxis.High= WindowVer/HighFlag。

8, in Y-direction window across screen time: as it is shown in fig. 7, the origin coordinates of 1-0 display unit Y is negative, Need across screen.Its window display height equal to unit thus have resolution, i.e. WindowAxis.High= WindowVer, image vertical shear height highly accounts for the ratio of whole window height equal to the display of this unit, i.e. SignalAxis.High=WindowVer/HighFlag.

In other embodiments, also by other pre-set shear parameters rule that those skilled in the art are usual Then, described resolution, described unit coordinate and described intrinsic resolution are converted to a left side for described display unit Eye pattern is as shear parameters.

For step S103, can be by described in the signal acquisition of the signal source output of the described input signal of detection The signal format of input signal, it is possible to receive the signal format of the described input signal of other module correspondences input, Also can obtain the format identification (FID) preset from the blanking zone of described input signal and obtain the signal lattice of described input signal Formula.

For step S104, various signal format can be prestored corresponding according to the signal format of 3D signal Translation parameters.3D signal preferably includes digital visual interface (DVI) form 3D signal, high-resolution The top-down format 3D signal of degree multimedia interface (HDMI) and the left-right format of HDMI 3D signal.

Preferably, described translation parameters is coordinate translation vector, for translating described left eye in system coordinates Horizontal shear original position and described left eye vertical shear original position.

In one embodiment, if described signal format is digital visual interface form, by described left eye level Shear original position and described left eye vertical shear original position, according to putting down corresponding to the signal format identified Shifting parameter carries out position translation, generates the right eye horizontal shear original position in eye image shear parameters and the right side The step of eye vertical shear original position comprises the following steps:

Make described left eye horizontal shear original position equal to described right eye horizontal shear original position；

Described left eye vertical shear original position is translated V unit distance downward vertically, generates described right eye Vertical shear original position, V is the vertical resolution of described resolution.

In the present embodiment, when carrying out signal and shearing, need to use two processors respectively according to left eye figure Shear as parameter and eye image shear parameters complete signal.

In another embodiment, if described signal format is the top-down format of HDMI, By described left eye horizontal shear original position and described left eye vertical shear original position, according to the signal identified Translation parameters corresponding to form carries out position translation, and the right eye level generated in eye image shear parameters is cut The step cutting original position and right eye vertical shear original position comprises the following steps:

Make described left eye horizontal shear original position equal to described right eye horizontal shear original position.

Described left eye vertical shear original position is translated M unit distance downward vertically, generates described right eye Vertical shear original position, M is the vertical resolution invalid letter plus described input signal of described resolution The half in number region.

According to described left eye vertical shear original position and described left eye vertical shear height, it is judged that left eye is sheared Height whether in the invalid signals region of described input signal.

If it is not, then left eye vertical shear height accounts for the ratio of whole window height equal to described display unit height It is multiplied by the vertical resolution of described resolution again.

The most then left eye vertical shear height deducts left eye equal to the vertical resolution of described resolution and vertically cuts Cut original position.

In the present embodiment, the 3D signal of HDMI is framepacking, and there is invalid signal area centre (ActiveSpace), if vertical direction clips to inside ActiveSpace so arises that portion in right eye Pixel is divided to lose.Therefore when the final position invalid signals region in described input signal that left eye is sheared, Described left eye vertical shear original position is translated M unit distance downward vertically, generates described right eye vertical Shearing original position, for the 3D signal that resolution is 1080P, ActiveSpace is 46, and M is 1080+23, the size of the ActiveSpace of the 3D signal of different resolution is as shown in table 1:

For shear parameters modular converter 200, described pre-set shear parameter rule is preferably 2D fenestration procedure In algorithmic rule that signal is sheared.

Preferably, as in figure 2 it is shown, mosaic display screen includes 0-0 display unit, 0-1 display unit, 1-0 Display unit and 1-1 display unit, leave the 3D window at display screen, has only to display for 0-0 display unit Signal upper left hand corner section, other positions need not, and 1-0 display unit has only to the lower left corner part of entire image, Other display units have only to the content specifying position of whole image, if it is incorrect to shear content, The last width that just cannot be spliced into shows picture.Clip image can define by four parameters: horizontal shear rises Beginning position, horizontal shear length, vertical shear original position, vertical shear height.

In one embodiment, left-eye image shear parameters and the window display parameter of each display unit are obtained Mark as follows:

The unit coordinate of display unit includes horizontal origin coordinates SignalWindow [i] .StartX, horizontal width SignalWindow [i] .Width, vertical origin coordinates SignalWindow [i] .StartY and vertical height SignalWindow[i].High。

Image cut parameter includes horizontal shear original position SignalAxis.StartXoffset, horizontal shear width SignalAxis.Width, vertical shear original position SignalAxis.StartYoffset and vertical shear height SignalAxis.High。

Image display parameters includes that window shows horizontal original position WindowAxis.StartX, window display width Degree WindowAxis.Width, window display vertical starting position WindowAxis.StartY and window display height Degree WindowAxis.High.

The intrinsic resolution of display unit includes intrinsic horizontal resolution WindowHor and intrinsic vertical resolution WindowVer。

The horizontal resolution of the resolution (resolution of the signal of window interior needs display) of input signal is SinnalHor, vertical resolution is SinnalVer.

Horizontal scaling coefficient WidthFlag is the ratio of SignalWindow [i] .Width Yu SinnalHor, hangs down Straight zoom factor HighFlag is the ratio of SignalWindow [i] .High Yu SinnalVer.

The rule obtaining the image cut parameter of each display unit and window display parameter is as follows:

One, the trunnion axis X-coordinate of display unit is timing: the starting point of display window and rising of unit coordinate SignalWindow [i] .StartX of initial point is identical.The start bit set 0 (Far Left of image) of clip image, Situation in two below image cut length gauge point counting:

1, X-direction window is not across screen:

During as it is shown on figure 3, window is not across screen, in 0-0 display unit, window lateral length is not above level admittedly There is resolution (i.e. SignalWindow [i] .StartX+SignalWindow [i] .Width≤WindowHor). So width of resize-window is equal to width (the i.e. WindowAxis.Width=of unit coordinate SignalWindow[i].Width).Image level shows all images on direction, therefore image cut width etc. Horizontal resolution (i.e. SignalAxis.Width=SinnalHor) in signal.

2, X-direction window is across screen:

As shown in Figure 4, window is when screen, and display unit 0-0 only shows a part for image, needs display Lateral length is less than width (i.e. SignalWindow [i] .StartX+ of unit coordinate SignalWindow[i].Width>WindowHor).Now window display width subtracts equal to display screen natural width Remove unit origin coordinates (i.e. WindowAxis.Width=WindowHor-SignalWindow [i] .StartX), The ratio that image cut width then accounts for SignalWindow [i] .Width according to WindowAxis.Width is counted Calculate.SinnalHor pixel to be put in SignalWindow [i] .Width, then the horizontal shear width of image Degree is: SignalAxis.Width be multiplied by WindowAxis.Width be multiplied by SinnalHor again divided by SignalWindow [i] .Width, i.e. horizontal scaling coefficient.

Two, the trunnion axis X-coordinate of display unit is for time negative: as shown in Figure 4, for 0-1 unit and 1-1 Unit, the unit coordinate X of 0-1 unit and 1-1 unit is negative, as a example by 0-1 unit, horizontal direction On parameter be calculated as follows:

Owing to display is from the beginning of 0 coordinate, so the original position of display window is 0, i.e. WindowAxis.StartX=0, the original position of image cut is not 0, it should eliminate the figure in 0-0 unit Picture, for 0-1 unit, the original position of image cut should be just that the shearing width of 0-0 unit adds 1, For 0-1 unit, the value of SignalWindow [i] .StartX is equal to the WindowAxis.Width of 0-0 unit, The shearing original position i.e. SignalAxis.StartXoffset=of 0-1 unit | SignalWindow [i] .StartX |/WidthFlag)+0.5, wherein SignalWindow [i] .StartX&0x7fff is that sign bit is removed, and adds 0.5 It is in order to parameter is rounded.

It is below two kinds of calculated level sheared lengths and the method for level display length:

3, X-direction window is not across screen:

Owing to not having across screen in 0-1 horizontal direction, window display width is equal to the horizontal width of unit coordinate and subtracts Remove horizontal origin coordinates, i.e. WindowAxis.Width=SignalWindow [i] .Width- (SignalWindow[i].StartX&0x7fff).Image level shearing width ibid, can be according to ratio by window Width obtains divided by zoom factor.That is: SignalAxis.Width =WindowAxis.Width/WidthFlag+0.5.

4, X-direction window is across screen:

As it is shown in figure 5,0-1 unit is in the horizontal direction across screen to 0-2 unit, now window display width WindowAxis.Width is equal to the intrinsic resolution WindowHor in the horizontal direction of display, image water Flat shearing width i.e. WindowHor are divided by zoom factor.I.e. SignalAxis.Width= WindowHor/WidthFlag。

Three, the vertical axis Y coordinate of display unit is timing: as shown in Figure 4, for 0-0 unit, Y side Coordinate upwards is just, the original position of resize-window is equal to the original position of unit coordinate i.e. WindowAxis.StartY=SignalWindow [i] .StartY, the original position that signal Y-direction is sheared is 0 I.e. SignalAxis.StartYoffset=0.

5, when in Y-direction, window is not across screen:

As shown in Figure 6, in Y-direction, the height sum of the original position of display window and display window is less than or equal to The intrinsic resolution of display unit vertical direction i.e. SignalWindow [i] .StartY+ SignalWindow [i] .High)≤WindowVer, at this moment window shows and is highly equal to the vertical of display unit Highly (WindowAxis.High=SignalWindow [i] .High).Image cut height is equal to inside image The vertical resolution divided, i.e. SignalAxis.High=SinnalVer.

6, in Y-direction window across screen time:

As shown in Figure 4, Y-direction needing across screen, now window display height is equal to 0-0 unit vertical direction Intrinsic resolution deducts the original position of display unit Y, i.e. WindowAxis.High=WindowVer- SignalWindow [i] .StartY, the image in image Y-direction is only with a display part, its image cut height Spend the ratio calculating accounting for whole display height according to 0-0 unit, i.e. SignalAxis.High =WindowAxis.High/HighFlag, SignalAxis.High=WindowAxis.High*SinnalVer/ SignalWindow[i].High/SinnalVer。

Four, the vertical axis Y coordinate of display unit is for time negative:

7, when in Y-direction, window is not across screen: as shown in Figure 4, for 1-0 unit, the initial seat of Y Mark is negative value, calculates the shearing zoom factor of 1-0 unit below.Window shows that horizontal original position is 0, i.e. WindowAxis.StartY=0, image cut vertical starting position adds 1 equal to the height of a upper unit, upper list The height that unit the shears original position equal to unit coordinate Y is divided by zoom factor.I.e. SignalAxis.StartYoffset=| SignalWindow [i] .StartY |/HighFlag+0.5.Window display height etc. In the height of unit coordinate, i.e. WindowAxis.Width=WindowHor.Image vertical shear height is pressed In this unit, scaling window height accounts for the ratio calculating of whole display window height, i.e. SignalAxis.High= WindowVer/HighFlag。

8, in Y-direction window across screen time: as it is shown in fig. 7, the origin coordinates of 1-0 unit Y be negative, needs Across screen.Its window display height equal to unit thus have resolution, i.e. WindowAxis.High= WindowVer, image vertical shear height highly accounts for the ratio of whole window height equal to the display of this unit, i.e. SignalAxis.High=WindowVer/HighFlag.
