Problems solved by technology
[0004] However, in current portable terminals with a 3D shooting function, the first lens and the second lens are set to be unable to rotate (eg Figure 9A shown), that is, the optical axes of the two lenses can only be two optical axes parallel in a specific direction, and the angle of the optical axes cannot be adjusted with the change of the focus, which makes when the subject is closer to the lens, The 3D images captured are seriously ghosted and cannot restore the true stereoscopic vision
[0005] In addition, although a motor device for inclining the lens to a certain angle is provided in a large-scale 3D shooting device, the motor device has a complex structure and high cost, and is not suitable for being installed in a portable terminal.
[0006] Therefore, it is difficult for existing portable terminals to obtain realistic stereoscopic images when shooting 3D images.

The invention provides equipment for adjusting lens of portable terminals. The equipment comprises a lens unit, an inclination angle determination unit and an optical image stabilizer unit. The lens unit comprises a first lens and a second lens and used for focusing a shot object; the inclination angle determination unit is used for determining inclination angles of the first lens and the second lens inclined towards the shot object after the shot object is focused; the optical image stabilizer unit comprises a first optical image stabilizer and a second optical image stabilizer. The first optical image stabilizer is used for impelling the first lens to incline towards the shot object by the determined angle, and the second optical image stabilizer is used for impelling the second lens to incline towards the shot object by the determined angle. The equipment and the method for adjusting the lens of the portable terminals have the advantages that the inclination angles of the first lens and the second lens in 3D (three dimensional) shooting can be adjusted by the aid of the optical image stabilizers in the portable terminals, and accordingly vivid three-dimensional images can be obtained.
Description
technical field [0001] The present invention generally relates to a technique of capturing 3D (3-dimensional) images in a portable terminal. More specifically, it relates to a device and method for adjusting a lens in a portable terminal with a 3D shooting function. Background technique [0002] A device for shooting 3D usually adopts two lenses (ie, a first lens and a second lens) for shooting. Specifically, in order to simulate human eyes, the first lens and the second lens are placed horizontally and separated by a certain distance. Here, as an example, the first lens and the second lens may correspond to the left eye and the right eye of a person respectively. Generally, the image sensor captures 3D images (including left and right views) respectively corresponding to left-eye views and right-eye views. When the user watches the captured 3D image through the 3D display device, the 3D display device presents the left view and the right view to the user's left eye and ri...
