A “Panoramic Viewfinder” provides an intuitive interactive viewfinder display which operates on a digital camera display screen. This interactive viewfinder provides real-time assistance in capturing images for constructing panoramic image mosaics. The Panoramic Viewfinder “brushes” a panorama from images captured in any order, while providing visual feedback to the user for ensuring that desired scene elements will appear in the final panorama. This visual feedback presents real-time stitched previews of the panorama while capturing images. In one embodiment, the viewfinder display of the Panoramic Viewfinder includes a “mosaic preview” which presents a stitched mosaic preview of the captured images; a live display window representing a “current content” of the camera viewfinder, which is mapped to a matching location within the mosaic preview; and an optional panoramic “cropping frame” overlaid onto the mosaic preview which illustrates a section of the mosaic which will survive a rectangular cropping of the mosaic.
