FIELD: physics. ^ SUBSTANCE: device for filtration of television images comprises serially connected detector of analog video signal (1), analog-digital transducer (2), and method for connection of counting delay units and electronic keys provides for combination of pixels that makes it possible to perform operation of discrete compression of image inlet signal and pulse characteristic of filter, at that device also comprises unit (8), in which with the help of amplifiers and summators value of image filtered pixel brightness is calculated, unit (7), which defines moment of beginning and ending of frame processing, unit for control of amplification ratio values of amplifiers. ^ EFFECT: increased accuracy of filtration, with the possibility to adjust filter to separate different structures on background of reflections from area. ^ 5 dwg |
