Four cameras (52,54, 56, 58) provide a 360 degree view of an area using a four sided pyramid shaped element (40). The four sides of the pyramid shaped element (40) are reflective and reflect images from four different directions. Each camera is positioned to receive a reflected image from one of the reflective sides of the pyramids. The cameras are arranged so that they share a common virtual optical center (90). Pixel data from the cameras is stored in a memory (172), and the data is selectively retrieved from the memory for viewing based on a user's input. |
