Abstract

Most camera systems only record an image from a limited viewing angle. A new panoramic camera apparatus is disclosed that instantaneously captures a 360 degree panoramic image. In the camera device, virtually all of the light that converges on a point in space is captured. Specifically, in the camera of the present invention, light striking this point in space is captured if it comes from any direction, 360 degrees around the point and from angles 50 degrees or more above and below the horizon. The panoramic image is recorded as a two dimensional annular image. Furthermore, various different systems for displaying the panoramic images and distributing the panoramic images. Specifically, methods and apparatus for digitally performing a geometric transformation of the two dimensional annular image into rectangular projections such that the panoramic image can be displayed using conventional methods such as printed images and televised images.

Claims

1. A method of presenting panoramic images, said method comprising the steps of:

recording an annular representation of a panorama;

storing said annular representation of said panorama as a digitized annular representation;

geometrically transforming said digitized annular representation of said panorama into a rectangular projection of said panorama; and

displaying said rectangular projection of said panorama,

wherein said step of geometrically transforming further comprises sampling said digitized annular representation with a dynamically changing sampling shape wherein said sampling shape is dependent upon a viewing angle.

2. A method of presenting panoramic images, said method comprising the steps of:

recording an annular representation of a panorama;

storing said annular representation of said panorama as a digitized annular representation;

geometrically transforming said digitized annular representation of said panorama into a rectangular projection of said panorama; and

displaying said rectangular projection of said panorama,

wherein said step of geometrically transforming further comprises sampling said digitized annular representation with a dynamically changing sampling shape orientation wherein said sampling shape orientation is dependent upon a horizontal viewing angle.

3. A method of presenting panoramic images, said method comprising the steps of:

recording an annular representation of a panorama;

storing said annular representation of said panorama as a digitized annular representation;

geometrically transforming said digitized annular representation of said panorama into a cylindrical representation of said panorama; and

displaying said cylindrical representation of said panorama using a computer program.

4. The method as claimed in claim 3 wherein said step of displaying said cylindrical representation of said panorama using a computer program comprises running a QuickTime VR program.
