Method and system for thermal imaging having a selective temperature imaging mode
DCFirst Claim
1. A thermal imaging system having a fixed hot colorization mode and a selective temperature imaging mode, said system comprising:
- a thermal sensing component for continually acquiring thermal image data for a scene;
a first input for receiving a command to exit said fixed hot colorization mode and enter said selective temperature imaging mode, said fixed hot colorization mode having fixed temperature ranges wherein portions of thermal images corresponding to said fixed temperature ranges are displayed in predetermined colors, said selective temperature imaging mode having a set point value wherein portions of thermal images corresponding to temperatures higher than the set point value are displayed in an alternate color and portions of said images corresponding to temperatures less than said set point value are displayed in a grayscale representation, the set point value being incrementally adjustable;
a second input for receiving a command to change the set point value;
a thermal imaging engine for;
generating thermal images in said selective temperature imaging mode from said thermal image data in response to receiving a command to exit said fixed hot colorization mode and enter said selective temperature imaging mode from said first input;
incrementally changing the set point value to a new desired set point value in response to receiving a command to change the set point value from said second input; and
generating thermal images from said thermal image data wherein portions of said images corresponding to temperatures higher than said new desired set point value are displayed in said alternate color and portions of said images corresponding to temperatures less than said new set point value are displayed in the grayscale representation; and
a display component for displaying said thermal images.

Abstract
The present invention is a method for operating a thermal imaging camera for selective temperature imaging, and a thermal imaging system having a selective temperature imaging mode. When first entering the selective temperature imaging mode of operation, the system and method automatically determine the hottest area in a scene and display it in a predetermined hue. The remainder of the scene is displayed in grayscale. The method and system allow further adjustment of the set point of the selective temperature imaging mode, and display portions of the scene as hot as or hotter than the set point value in gradient shades of the predetermined hue.
