摘要： An image processing method includes: receiving a plurality of images, the images being captured under different view points; and performing image alignment for the plurality of images by warping the plurality of images, where the plurality of images are warped according to a set of parameters, and the set of parameters are obtained by finding a solution constrained to predetermined ranges of physical camera parameters. In particular, the step of performing the image alignment further includes: automatically performing the image alignment to reproduce a three-dimensional (3D) visual effect, where the plurality of images is captured by utilizing a camera module, and the camera module is not calibrated with regard to the view points. For example, the 3D visual effect can be a multi-angle view (MAV) visual effect. In another example, the 3D visual effect can be a 3D panorama visual effect. An associated apparatus is also provided.

摘要： A stereo preview apparatus has an auto-stereoscopic display, an input interface, a motion detection circuit, and a visual transition circuit. The input interface receives at least an input stereo image pair including a left-view image and a right-view image generated from an image capture device. The motion detection circuit evaluates a motion status of the image capture device. The visual transition circuit generates an output stereo image pair based on the input stereo image pair, and outputs the output stereo image pair to the auto-stereoscopic display for stereo preview, wherein the visual transition circuit refers to the evaluated motion status to configure adjustment made to the input stereo image pair when generating the output stereo image pair.

摘要： An auto-convergence system includes a disparity unit, a convergence unit and an active learning unit. The disparity unit performs a disparity analysis upon an input stereo image pair, and accordingly obtains a disparity distribution of the input stereo image pair. The convergence unit adjusts the input stereo image pair adaptively according to the disparity distribution and a learned convergence range, and accordingly generates an output stereo image pair for playback. The active learning unit actively learns a convergence range during playback of stereo image pairs, and accordingly determines the learned convergence range.
