1. A method performed by a computing device having a processor and memory for combining a first frame and a second frame, comprising:
- determining by the computing device horizontal and vertical offsets for spatially aligning the first and second frames, comprising summing absolute values of color differences between the first frame and the second frame at a multiplicity of pixel locations, based on trial values for horizontal and vertical offsets;
further determining by the computing device brightness and contrast parameters for chromatically aligning the first and second frames; and
generating by the computing device a panoramic image, comprising compositing a portion of the second frame onto a portion of the first frame, based on the horizontal and vertical offsets and based on the brightness and contrast parameters.

Abstract
A camera including a camera lens, acquisition circuitry receiving images via the camera lens, for acquiring a first field of view when the camera lens is in a first orientation and for acquiring a second field of view when the camera lens is in a second orientation, and a viewfinder displaying the second field of view when the camera lens is in the second orientation and displaying at least a portion of the first field of view at least partially composited with the second field of view.

13. A computer-readable storage medium storing instructions that, when executed, perform a method of combining a first frame and a second frame, the method comprising:
-
determining horizontal and vertical offsets for spatially aligning the first and second frames by at least summing absolute values of color differences between the first frame and the second frame at multiple pixel locations; determining brightness and contrast parameters for chromatically aligning the first and second frames; and generating an image, comprising compositing a portion of the second frame onto a portion of the first frame based on the horizontal and vertical offsets and based on the brightness and contrast parameters. - View Dependent Claims (14, 15, 16)

21. A camera, comprising:
-
a camera lens; acquisition circuitry configured to receive images via the camera lens to acquire a first field of view if the camera lens is in a first orientation and to acquire a second field of view if the camera lens is in a second orientation; and a viewfinder configured to display the second field of view if the camera lens is in the second orientation and to display at least a portion of the first field of view at least partially composited with the second field of view, wherein the portion of the first field of view comprises a section of the first field of view. - View Dependent Claims (22)
