摘要： A reflective rotund lens is positioned for projecting a panoramic picture of its horizontal surroundings at a given elevation onto a CCD array, for converting the picture into “pixel form” or an image signal. The image signal is digitized via an A/D converter circuit. A digital signal processor system is programmed for extracting a strip of pixel locations representative of an image ring mapped to pixel locations via superimposition upon the image, whereby all pixel locations outside of the image ring are eliminated by passing the pixels thereof through said A/D converter circuit at a rate higher than the conversion rate of said A/D converter circuit.

摘要： An omnidirectional light sensor is provided in a disk-like housing including a plurality of successive spaced apart individual radially directed capsules, each including a lens in a frontmost opening on a side edge of the housing, for focussing light rays from surrounding scenery into the interior of the capsule. A prism or reflecting mirror in each capsule receives the focussed light rays for directing them onto an associated photosensor located radially inward in the capsule, for converting the light rays into pixels representing the associated image portion. The pixels form a panoramic digital data strip from the received image portions.
