METHOD OF GENERATING AND DISPLAYING COLOUR, SPECTROZONAL AND THERMAL IMAGE SIGNALS Russian patent published in 2015 - IPC H04N7/18 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to communication engineering and can be used for industrial television, for video surveillance of objects in surrounding space and combined generation of colour, spectrozonal and thermal images. The method comprises, after splitting input radiation flux into two identical streams, passing said streams through two broadband optical filters, the first having a spectral characteristic overlapping a spectral portion in the visible spectral region, and forming the radiation flux at the output of the first optical filter; the spectral characteristic of the second optical filter overlaps the spectral portion in the visible and near infrared IK₁ spectral region; and forming radiation flux at the output of the second optical filter, followed by generating colour television video signals, generating spectrozonal television video signals, further setting up a third channel, for which input radiation flux is transmitted through an infrared lens, obtaining thermal imaging video signals corresponding to detection areas of the thermal portion of the spectral region, further amplifying and performing separate and combined digital processing of the generated video signals, displaying said signals for visual perception of images or automatic analysis of video information.

EFFECT: improved video information support and efficiency of the surveillance process and reliability of analysing objects of multi-component images.
