Description

high output) at the output of the second adder A generates a signal a) s 0.5 (high output 1 + high output) and at the output of the second subtraction unit 7 a signal ui high output 2 is generated (oz.

The signals from the outputs of the first and second 7 subtraction blocks are fed to the inputs of the color vector module determining unit 9 and the color vector phase determining unit 1.0. At the output of the color vector module determining unit 9, a signal p equal to

p V

Wl 2 -f ftЈ 2

and at the output of the color vector phase determination unit 10, a signal p equal to

p arctg wi / Ofe

The signal p, proportional to the color vector module, about the output of the module for determining the color vector module 9, is supplied to the corresponding input of the divider 8, to the other input of which the total signal U 2 ™

 Ueuxi + out2 + 1) Exit from the output of the first adder 3, and at the output of the divider 8, a saturation (or color purity) signal is generated, which is fed to the first comparison element 11, where it is compared with the saturation reference and if the measured value matches the reference in within a certain tolerance, the output of the first comparison element 11 shows the level of a logical unit. With a significant discrepancy (excess or understatement) of the measured saturation value with respect to the reference output of the first comparison element 11, a logic level of zero is established).

The channels of color tone (blocks 12 and 15) and brightness (13 and 16) work similarly. Meanwhile, a color vector phase signal is supplied to the second comparison element 12 through the first delay element 17. A signal proportional to the brightness of each point of the analyzed image from the output of the third adder 5 is supplied to the third comparison element 13 through the second delay element 18.

At the same time, the signal of the color components from the output of block 1 goes to the inputs of the third adder 5 and to the information inputs of the keys 24-25 through delay elements 19-21. The control inputs of the keys 24-26 receive a logical unit signal from the output of the And 23 element at that time when the color characteristics of the same or another area of the frame coincide with the reference values of a given color within certain limits.
