Device.All it is by making the variation of physical arrangement or shooting state to camera come real in single camera filming apparatus
Existing 3D shootings, or be plus photoswitch or be that camera lens or so moves back and forth or rotary taking, but moves camera lens and clapping
The image obtained when swiftly passing object is taken the photograph to will not be sufficient to clearly.In multi-cam filming apparatus, generally use two is taken the photograph
The shooting of 3D images is realized as the eyes of head mould personification, and left eye camera and right eye camera are provided on 3D video cameras,
Left eye camera is used to shoot the image letter exported to right eye for shooting the picture signal exported to left eye, right eye camera
Number.
In mobile device terminal, two camera placement position consistencies from top to bottom, in order to shoot with horizontal parallax
3D rendering is supplied to image synthesis system, it is desirable that by 90 degree of screen rotation, laterally（landscape type）Put, two camera lenses by
Consistency from top to bottom is converted into left and right alignment, and left side camera is used to shoot eye image for shooting left-eye image, the right camera,
Taken image parallactic is present in left and right directions, and there is no parallaxes for upper and lower directions, therefore, it is captured out image also only
It can watch under screen transverse direction, and be placed vertically in screen（portrait type）Under can not watch 3D, such situation is not easy to personage
The 3D of portrait is shot.

3）First original image is cut, one fixed width is dismissed into top and the right respectively, obtains the first processing figure
Picture cuts second original image, and one fixed width is dismissed on the following and left side respectively, obtains second processing image,
Wherein, the width that the long side of first original image and second original image is dismissed is N, and the width that short side is dismissed is M,
The ratio of width M and width N are equal to L2/L1；
4）Image is handled by described first and the second processing image is amplified to screen resolution size respectively, as left eye
Image and eye image；
5）The amplified left-eye image and the eye image are exported.
According to the present invention of said program, advantage is, the present invention by adjusting camera relative position and
Image algorithm, to obtain the left images with transverse screen parallax for transverse screen display and obtain the left images with vertical screen parallax
For vertical screen display, taken image parallactic is present in left and right directions, and there is no parallaxes for upper and lower directions, meet transverse screen and erect
Shield compatible demand.
