FIELD: physics, optics.
SUBSTANCE: invention relates to means of generating spectrozonal electronic images. In the method, decomposition of an optical image into spectral zones is carried out using a variable interference filter located in the plane of the optical image. During the period of generating one video frame, the variable interference filter is shifted relative to the optical image by the value of a spectral zone. Spectrozonal video frames are formed from the stored video frames by sampling, from the stored frames, arrays of lines with video images obtained in the same spectral zones.
EFFECT: real-time variation of the spectral width of spectrozonal video frames.
