Method and system for thermal imaging having a selective temperature imaging mode
DCFirst Claim
1. A method of operating a thermal imaging camera for selective temperature imaging, comprising the steps of:
- analyzing thermal image data for a scene to determine a highest temperature in said scene in response to receiving a command to enter a selective temperature imaging mode;
displaying a thermal image of said scene with the portions of the image equal to said highest temperature displayed in a predetermined hue and the remainder of the image displayed in grayscale, such that the highest temperature portions of the thermal image are selectively highlighted in said predetermined hue in contrast to the grayscale display of the remaining portions of the thermal image.

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.
