Abstract: A bispectral pick-up and false color display system which comprises a bispectral camera for analyzing a picture in the visible range and a picture in the infrared range, and outputting two respective video signals, one for the visible range and one for the infrared range. A mixer then mixes these two video signals and derives, therefrom, three color control signals, each color control signal being a linear combination of the two video signals given by the bispectral camera. A manual setting device then sets or adjusts the coefficients of each of the combinations. A standard color television monitor then can display a picture as a function of the three color control signals. The disclosed device can be applied to target-sighting and target-tracking devices for land vehicles.
