摘要： An image-shooting method with guide for taking stereo images is used in a camera system. The camera system utilizes a same lens to take images. The method includes the following steps. A shooting mode is selected. A guiding information is provided by a display unit. A set of images for a target image field is taken by moving the lens to multiple guiding locations according to the guiding information, in which the set of images is at least two view-angle images with different view angles. The view-angle images are corrected with a stereo visual effect. The set of view-angle images is output, and meanwhile, a corresponding shooting information is output. Then, the view-angle images are adjusted according to the shooting information, so as to achieve a desirable stereo display effect.

摘要： A method for calibrating a response curve of a camera is provided. A homography relationship of an image sequence captured by the camera is calculated using a coplanar information including feature correspondence blocks of the image sequence. An intensity mapping function is then obtained from the intensity information of the correspondence blocks according to the homography relationship.

The embodiments are based on an image database with depth information or with which depth information can be generated. With respect to a 2D image to be converted into 3D content, a matched background image is found from the database. In addition, graph-based segmentation and comparison techniques are employed to detect the foreground of the 2D image so that the relative depth map can be generated from the foreground and background information. Therefore, the 3D content can be provided with the 2D image plus the depth information. Thus, users can rapidly obtain the 3D content from the 2D image automatically and the rendering of the 3D content can be achieved.
