Abstract: A device for creating a panoramic image from a plurality of images taken by a digital camera. The device comprising: an input for receiving a current image which is updated in real time when a digital image capture mechanism coupled to the input is repositioned. The device further includes a preview generator for warping or mathematically adjusting perspective of a portion of a stored previous image so as to generate an overlap portion for optimal alignment by a user of the overlap portion to the current image therewith. The warped overlap portion of the stored previous image along with the current image is presented to a viewfinder. In an alternate embodiment, a method and computer readable medium corresponding to the above system is described.

Abstract: A method in a digital camera for image capturing at least two perspective images at a constant focal length from the digital camera, where both images share a common edge portion. The method including: recording a first image from a first perspective; displaying a preview of a second image from a second perspective; simultaneously with displaying the preview, presenting an overlapping edge region of the first image to allow alignment of the first image with the preview of the second image; and correcting the perspective of at least one image in an overlapping edge region. In an alternate embodiment, a digital camera and computer readable medium corresponding to the above method is described.

Abstract: A method for estimating the motion between a first image and a second image in a system for creating a panoramic image from a plurality of images taken by a camera, the method comprising the steps of: downsampling a first image in a first direction and in a second direction; downsampling a second image in a first direction and in a second direction; filtering the first and the second image so as to filter out any global illumination changes between the first image and the second image; calculating a first displacement along the first direction between the first downsampled image along the first direction and the second downsampled image along the first direction; and calculating a second displacement along the second direction between the first downsampled image along the second direction and the second downsampled image along the second direction. In an alternate embodiment, a device and computer readable medium corresponding to the above method is described.

Abstract: A method for converting a rectilinear image and a focal length into a cylindrical image parameterized by a height of the cylinder and an angular distance in a single buffer on a remote processing device. The method, on the remote processing device, comprising joining two or more images together to form a panoramic image with corrected perspective. The rectilinear transformation is “in-place” and requires only one buffer. Color correction and motion estimation is also carried out on the remote device. In an alternate embodiment, a computer readable medium corresponding to the above method is described.

Abstract: A method for correcting color in a system for creating a panoramic image from a plurality of images taken by a camera. The method comprising the steps of: receiving a color channel from at least a first image and a second image; creating an overlap portion between the first image and second image; and adjusting the color channel for the first image and for the second image in at least the overlap portion between the first image and the second image which is independent of motion estimation. In an alternate embodiment, a system and computer readable medium corresponding to the above method is described.

Abstract: A method and system for modifying a panoramic image of a scene, so as to alter its surface geometry, including providing an initial panoramic image of a scene projected onto an initial surface, generating, in response to user input, a desired surface upon which the scene is to be projected, and modifying the initial panoramic image by mapping points on the desired surface to corresponding points on the initial surface to produce a modified panoramic image corresponding to projection of the scene onto the desired surface.

Abstract: A method for centering a plurality of images which are snapshots of an object seen at a plurality of orientations, including computing modification parameters for the images, and modifying the images based upon the modification parameters using a computer.

Abstract: A method and system for constructing a panoramic image including the steps of applying panoramic curvature to at least one image, thereby to create a panoramic background embedding in the panoramic background an additional image having a geometry other than that of the panoramic curvature thereby to provide a composite panoramic image containing an embedded image corresponding to the additional image and whose geometry matches that of the panoramic background.
