Television (TV) Sensor
The TV sensor is a charge-coupled device (CCD) television camera that enables the F-16C to identify targets at
long-range during daylight hours only. Although the TV sensor only includes one optical field-of-view and is less
versatile than the FLIR, the magnification of the TV sensor facilitates target identification at further distances
than is possible with the FLIR sensor
The TV should have a black screen, just like the picture within the picture.
