Can an infrared TV camera distinguish the color of an object?

There are two kinds of infrared photography: black and white and color.

Infrared photography is to distinguish infrared wavelength light, infrared light wave is invisible, and color is visible light with different wavelengths, so color infrared photography cannot reflect the actual color.

Black and white pictures in infrared photography generally use white for high temperature and black for low temperature, but the color of the actual object may be just the opposite. For example, if a black object absorbs heat well and has a high temperature, it will appear white when viewed in an infrared photographic picture.

Similarly, in infrared images of color photography, warm colors such as red and yellow are used to represent high temperature, while cool colors such as blue and green are used to represent low temperature. In fact, black objects have good heat absorption, and if the temperature is high, they may tend to be red or yellow in color images.

So if you wear black clothes, you can't escape the night vision device at night. No matter what color clothes people wear, they may be translucent in infrared photographic images.

In addition, the night vision function of the camera:

Active infrared night vision means that in the night vision state, the camera will emit infrared rays invisible to the naked eye to illuminate the photographed object, and the infrared rays will enter the lens for imaging after being reflected by the object. The characteristic of this kind of night vision is that it can be shot without light at all, but because infrared photography is adopted, the color cannot be restored, so the shot picture is black and white.

Color night vision camera does not emit any light, but it prolongs the exposure time of CCD, so that the charge generated by CCD light can be accumulated, and the camera circuit can be used for high gain work. Its characteristic is that the shooting location must have at least 1LUX light (about the brightness of a candle), and the shot picture is color. However, due to the extension of CCD exposure time, the shot picture is discontinuous, which will cause the picture tailing phenomenon.
