Image processing system
First Claim
1. An image processing system including a plurality of linear arrays of detectors imaged onto a scene of interest and an image store for receiving signals from the linear array when a detected object passes through the scene;
- wherein the plurality of linear arrays of detectors are spaced substantially parallel to one another to image a plurality of areas of interest in a scene; and
the system further comprises a signal processor for detecting images received by the plurality of arrays and determining direction and speed of movement detected.

Abstract
An image processing system includes a plurality of vertically arranged linear arrays of detectors imaged onto a plurality of areas in a scene of interest. Horizontal movement of an object through the plurality of areas of interest are detected and fed into a processor. The processor may detect object range, direction of movement, speed, true direction of travel, object type. The detectors may be sensitive in the infra red (IR), microwave (including mm wave devices), or visible wavebands, operating with ambient or artificial illumination. In some application a combination of IR and visible detectors may be used. Preferably each detector in the linear array has an associated amplifier and filter. A 360° cover may be obtained by combining several systems into a single unit. The system may be used to detect objects and then control operation of a higher definition two-dimensional detector array and camera.
