Abstract
An infrared (IR) light camera or sensor that provides temperature alarms. The temperature alarms may be audible, vibrational, and visual to indicate when a portion of the IR image meets user-defined alarm criteria. Visual alarms may be provided by displaying on a camera display unit the portions of the IR image that meet the alarm criteria.
Claims35
A camera for producing visible-light (VL) images and infrared (IR) images, comprising:
- an array of VL sensors for sensing VL images of a target scene;
- an array of IR sensors for sensing IR images of the target scene;
- and
- a display for concurrently displaying portions of the sensed IR images and the sensed VL images of the target scene registered to form a composite image, the display displaying only the portions of the sensed IR images meeting at least one alarm criterion, the portions of the sensed IR images meeting the at least one alarm criterion are flashed on and off the display.
1 more element
A hand-held camera for producing infrared (IR) images, comprising:
- an IR camera module supported by a camera housing and having IR sensors and IR optics, the IR sensors including an array of IR sensors for sensing IR images of a target scene;
- and
- a display supported by the camera housing for displaying portions of the sensed IR images of the target scene, the display displaying only the portions of the sensed IR images meeting at least one user-defined alarm criterion, the at least one user-defined alarm criterion including a relative threshold defined as a range of temperatures within a pre-defined number of degrees of a reference temperature, whereby the portions of the sensed IR images within the range are displayed.
