Problems solved by technology
[0002] Known from the prior art, three-dimensional visual effect reproduction (three-dimensional visual effect reproduction, 3D visual effect reproduction) usually requires the preparation of source images and complex calculations
During the preparation stage, problems can occur whether the resolution of the source image is high or low, for example, the source image should be captured by a pre-calibrated camera, where the pre-calibrated camera should have been corrected by a predetermined view point or predetermined line of view, thus causing difficulties in preparing source images
In another example, in order to efficiently perform complex calculations, it is necessary to prepare high-end computers with powerful computing capabilities, because traditional multifunctional mobile phones seem to be unable to perform complex calculations. Operate smoothly under computational load, so high-end computers will not be replaced by traditional multifunctional mobile phones, that is, traditional multifunctional mobile phones will not be a complete solution for 3D production / reproduction
All in all, the existing technology cannot meet the needs of users, therefore, an innovative method of performing image processing for 3D visual effect reproduction in a smart and robust way is needed for portable electronic device (portable electronic device) ) (for example, a multifunctional mobile phone) to realize the above-mentioned source image preparation and related calculations

Embodiment Construction
[0026] Certain terms are used throughout the specification and following claims to refer to particular elements. Those skilled in the art should understand that manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as the way to distinguish components, but the difference in function of the components as the basis for the difference. "Includes" mentioned throughout the description and claims is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly connected to the second device, or indirectly connected to the second device through other devices or connection means.

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.
