Abstract:
A method of processing signals representative of a machine-sensed environment, comprising the steps of:sensing infrared radiation having wavelengths in the range of 1-microns to 2-microns to create a sensed electric light-source infrared signal;determining a relative location of at least one local maximum within the sensed electric light-source signal;sensing infrared radiation having wavelengths of at least 3-microns to produce a sensed background-scene signal; andproducing an image signal by:assigning levels of brightness to the sensed background-scene signal, assigning levels of brightness to at least one of the local maximums of the sensed electric light-source infrared signal that are greater than the level of brightness assigned to the sensed background-scene signal within the relative location of the at least one of the local maximums, andmapping the assigned levels of brightness to a display.
