Method and apparatus for composing a panoramic photograph
First Claim
1. A method, comprising:
- assembling a low-resolution video mosaic of a scene as a field of view of a camera is swept over the scene;
computing the number and locations of a set of high-resolution component photographs that tile the swept scene field of view; and
guiding a user of the camera to sweep the field of view of the camera over the scene a second time so that the location of each of the high-resolution component photographs is visited.

Abstract
Methods and apparatus are disclosed for guiding a camera user to take an appropriate set of component photographs to be stitched into a stitched panoramic photograph of a scene. In one example embodiment, the camera constructs and displays a video mosaic while the user sweeps the field of view of the camera over the scene. The camera computes the number and locations of a set of component photographs that will tile the scene, and then guides the user to sweep field of view of the camera over the scene a second time, visiting each component photograph location. A high-resolution component photograph may be taken at each location. Optionally, the camera gathers information from frames used to construct the video mosaic and uses the information to select settings for focus, exposure, or both to be used during the taking of the component photographs.

11. A camera, comprising:
-
an electronic array light sensor;
a lens that projects an image of a scene onto the electronic array light sensor;
a display; and
logic, the logic configured to construct a low-resolution video mosaic as the field of view of the camera is swept over the scene;
display the low-resolution video mosaic on the display;
calculate the number and locations of a set of high-resolution component photographs that tile the swept portion of the scene, the high-resolution component photographs to be stitched into a high-resolution panoramic photograph of the scene; and
guide a user of the camera to sweep the field of view of the camera over the scene a second time, visiting the location of each of the component photographs. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A method of taking component photographs to be stitched into a panoramic photograph, comprising:
-
a first phase during which a field of view of a camera is swept over a scene by a user and the camera constructs a low-resolution video mosaic of the swept scene field of view; and
a second phase during which the camera guides the user to sweep the camera field of view over the scene a second time, visiting locations of each of a set of component photographs that cover, with appropriate overlap, the field of view swept in the first phase. - View Dependent Claims (20)
