Visible light and ir combined image camera with a laser pointer

Abstract

Methods and apparatuses for registering on a camera display separate fields of view of a visible light camera module and an infrared camera module by focusing the IR camera module. The fields of view can be displayed in several display modes including 1) full screen visible, infrared and / or blended, 2) picture-in-a-picture such as partial infrared image in a full screen visible image, and 3) infrared color alarms in visible-light images.

Description

Background technique [0001] Many infrared cameras today use only energy in the far infrared part of the electromagnetic spectrum (typically in the range of 8-14 microns) to produce images of a scene (IR images). Images obtained using these cameras assign colors or grayscale levels to the pixels making up the scene based on the intensity of the IR radiation reaching the sensor elements of the cameras. Because the synthetic IR image is based on the temperature of the object, and because the colors or levels displayed by the camera do not typically correspond to the visible color of the scene, it is difficult, especially for beginners to such devices, to map the features of interest in the IR scene (e.g., thermal Spots) are accurately associated with their corresponding locations seen by the operator in the visible light scene. Infrared-only images can be especially difficult to interpret in applications where the contrast of the infrared scene is low. [0002] Infrared sights ...
