Abstract

An imaging system for obtaining a wide field of view comprises a plurality of imaging devices each having a defined field of view and each of the imaging devices having a mechanism for capturing an image at a selected time instant. The imaging devices are positioned such that the field of view of each device overlaps the field of view of each adjacent device. A control module simultaneously actuates each of the imaging devices to capturing an image within the field of view of all devices concurrently. The resulting images from each of the devices are merged to produce a wide field of view image.

Claims

1. An imaging system for obtaining wide field of view images comprising:

an array of lenses spaced uniformly about a common point;

an array of light sensors, each light sensor being associated with a respective one of the lenses for capturing an image impending on such lens; and

means for mounting the lenses such that a plane in which a lens is oriented is 22.5 degrees angular with respect to any plane of any adjacent lens.

2. The imaging system of claim 1 wherein the lens array is a hexadecagon.

3. The imaging system of claim 1 wherein each lens is smaller in diameter than the associated sensor.

4. The imaging system of claim 1 wherein the lens array is three-dimensional

5. The imaging system of claim 4 wherein the array mounting means is formed in the shape of a Bucky ball.

6. The imaging system of claim 5 wherein the number of lenses is greater than a number of facets on an equal size Bucky ball.

7. In an imaging system for creating a wide angle image from a plurality of narrow angle images, a method for preventing unauthorized use of the narrow angle images comprising:

collecting each of the narrow angle images;

determining a center image of the plurality of narrow angle images;

storing the center image in a standard image format;

encrypting each of the remaining narrow angle images; and

storing the encrypted images in association with the center image.

8. The method of claim 7 and including linking each encrypted image to the center image.

9. The method of claim 8 and including providing a decrypting algorithm that concurrently decrypts and combines the plurality of images into a composite image.

10. The method of claim 9 wherein the decrypting algorithm is operable in a printer for printing the composite image.
