Abstract
Digital cameras and methods that provide improved image alignment for panorama image capture. The present invention identifies features that will likely be used by a stitching algorithm, and highlights those features for a user by superimposing them on top of a “liveview” image presented on a display of the digital camera. By applying an edge detection algorithm to the previously captured image, the user can select and display those features of the previous image that are relevant to aligning the camera for the subsequent image.
