Thermal gunsights

A method comprising:

• providing a gunsight comprising a processor, a microbolometer and a display;
• receiving, with the processor, image signals from the microbolometer, the image signals corresponding to a first field of view, the first field of view having a first area;
• displaying an image on a display, the image corresponding to a second field of view, the second field of view having a second area, the first area being greater than the second area;
• analyzing the image signals with the processor and identifying one or more heat signatures located inside the first field of view and outside of the second field of view;
• displaying, on the display, an icon superimposed on the first image, the icon being displayed at an icon position, the icon position being selected based on a location of a selected one of the one or more heat signatures located inside the first field of view and outside of the second field of view.

A computer program product for aiming a firearm having a barrel defining a bore, the bore extending along a bore axis, the bore axis extending in a forward direction and a rearward direction, the computer program product comprising:

• a computer readable storage medium having program instructions embodied therewith, wherein the computer readable medium is not a transitory signal, the program instructions executable by a processor to cause the processor to:
• capture image signals with the microbolometer, the image signals corresponding to a first field of view, the first field of view having a first area;
• display an image, the image corresponding to a second field of view, the second field of view having a second area, the first area being greater than the second area;
• analyze the image signals from the microbolometer and identify one or more heat signatures located inside the first field of view and outside of the second field of view;
• display an icon superimposed on the first image, the icon being displayed at an icon position, the icon position being selected based on a location of a selected one of the one or more heat signatures located inside the first field of view and outside of the second field of view.
