Abstract
An infrared imager and a color TV camera view the same scene and the output signals are mixed and fed to a color television monitor so that the scene at night is visible in a black and white format with warm objects appearing dark, and bright colors such as lights appear in natural color superimposed on the black and white image.
Claims4
A night vision enhancement system comprising:
- a color monitor,
- means for displaying on the color monitor a monochrome image of a dimly lighted scene with a true color image of bright objects superimposed on the monochrome image, including
- an infrared imager viewing the scene and generating a monochrome signal,
- a color pickup viewing the same scene from the same viewpoint and generating a color signal representing lighted objects in the scene, and
- mixing means for combining and synchronizing the monochrome and color signals and transmitting the combined signal to the monitor, whereby the monitor displays a monochrome image of the scene with true color highlights imposed thereon.

A night vision enhancement system comprising:
- a color monitor,
- means for displaying on the color monitor a monochrome image of a dimly lighted scene with a true color image of bright objects superimposed on the monochrome image, including
- an infrared imager viewing the scene and generating a black and white monochrome signal representing warm objects in the scene as dark images and cold objects as light images,
- a color pickup viewing the same scene from the same viewpoint and generating a color signal representing lighted objects in the scene, and
- mixing means for combining and synchronizing the monochrome and color signals and transmitting the combined signal to the monitor, whereby the monitor displays a monochrome image of the scene with true color highlights imposed thereon.

A night vision enhancement system comprising:
- a color monitor;
- means for displaying on the color monitor a monochrome image of a dimly lighted scene with a true color image of bright objects superimposed on the monochrome image, including
- an infrared imager sensitive to the far infrared spectrum and insensitive to visible light for viewing the scene and generating a monochrome signal,
- a color pickup viewing the same scene from the same viewpoint and generating a color signal representing lighted objects in the scene, and
- mixing means for combining and synchronizing the monochrome and color signals and transmitting the combined signal to the monitor, whereby the monitor displays a monochrome image of the scene with true color highlights imposed thereon.

A night vision enhancement system comprising;
- a color monitor,
- means for displaying on the color monitor a monochrome image of a dimly lighted scene with a true color image of bright objects superimposed on the monochrome image, including
- an infrared imager sensitive to the mid infrared spectrum for viewing the scene and generating a monochrome signal independently of visible light,
- a color pickup viewing the same scene from the same viewpoint and generating a color signal representing lighted objects in the scene, and
- mixing means for combining and synchronizing the monochrome and color signals and transmitting the combined signal to the monitor, whereby the monitor displays a monochrome image of the scene with true color images imposed thereon.
