A computing device, such as a mobile device, can capture pictures or video images using a digital camera and obtain associated orientation information using an accelerometer. The orientation information can be used to adjust one or more of the captured pictures or video images to compensate for rotation in one or more planes of rotation. The orientation information can be saved along with the captured pictures or video images. The orientation information can also be transmitted or streamed along with the captured pictures or video images. Image matching operations can be performed using pictures or video images that have been adjusted using orientation information.

Using accelerometer information for determining orientation of pictures and video images

Composite video generation is described. In an embodiment, mobile video capture devices, such as mobile telephones, capture video streams of a common event. A network node receives the video streams and time-synchronizes them. Frames from each of the video streams are then stitched together to form a composite frame, and these are added to a composite video sequence. In embodiments, the composite video sequence is encoded and streamed to a user terminal over a communications network. In embodiments, the common event is a live event and the composite video sequence is generated in real-time. In some embodiments, the stitching of the video streams is performed by geometrically aligning the frames. In some embodiments, three or more mobile video capture devices provide video streams.
