摘要: A method for generating a 3D image utilizes a background image and an object image. A camera is used for capturing a 2D image including the background image and the object image. The object image is obtained from the 2D image according the background image. Then, an image from a first angle of view and an image from a second angle of view are generated by rendering the background image and the object image. So, the 3D image is generated by interweaving the image from the first angle of view and the image from the second angle of view.
