Abstract
An enhanced vision system for detecting radiation and producing a detected image signal. A signal processor compares the detected image signal with predefined data representing objects expected to be imaged, and produces an output signal based on the predefined data when sufficient similarity is found between the detected image signal and the predefined data. In some embodiments, the signal processor replaces the detected image signal with the predefined image data. In other embodiments, the signal processor combines some or all of the detected image signal data with the predefined image data. In still other embodiments, the signal processor first modifies the detected image signal data, e.g., by replacing portions of it representing electric lights with discrete dots located at the centers and/for locally maximum intensity values of the lights, and then combines the modified image signal data with the predefined image data.
