The invention relates to the field of automation and can be used for the analysis of biological objects.

The aim of the invention is to improve the accuracy of the device.

1 shows a diagram of the device; Fig. 2 is a control block diagram; on fig.Z - temporary diagrams

we work. devices; FIG. 4 shows the number of chords of the upper response measures, illustrating the operation of the device.

The device contains a television sensor 1, a control unit 2, a quantization unit 3, the first element is NOT 4.15

the first switch 5 is the memory block 6, the second element is NOT 7, the object signal extraction block 8, the second switch 9, the delay block 10.

The control unit contains an element 20 OR 11, the first trigger 12, the first element And 13, the counter 14, the second trigger 15, the second element And 16, the third trigger 17, the fourth trigger 18.

The device works as follows 25 times.

On the Reset signal, the first 12, second 15, and third 17 triggers of the control block 2 are set to match. It cannot exceed the number of lines in the frame.

Since the output of the first trigger 12 is the third output of the control unit 2, simultaneously passing through the second switch 9 of the signal from the output of memory block 6 and passing the signal from the output of the second element HE 7 is allowed (fig.4b). The inverted signal arrives at the first input of the block 8 for selecting the object signal and through the block 10 of the delay performing the delay for the horizontal scanning period to the second input of the block 8 for extracting the signal of the object. The signal from the output of the first trigger 12 is fed to the D-input of the fourth trigger 18, to the counting input of which is received XI. This trigger is a formative state. On the falling edge of the cad-30 start pulse corresponding to the high-frequency sync pulses (XI), the fourth trigger 18 is reset, since its input is connected to the output of the first trigger 12. The outputs of these triggers are output 5. management Thus, all outputs of the control unit 2 at the beginning of operation are in the initial (zero) state. In this case, the signal from the output 40 of the quantization unit 3 through the first switch 5 is allowed and the signal from the output of the first element HE 4 is not allowed to pass through, the signal from the output 45 of the memory block 6 through the second switch 9 is simultaneously allowed and the signal from the output of the second element is NOT 7. From the fourth output of the control unit 2, the operation mode of the memory block 6 is allowed, in which the information recorded in the previous frame is constantly read. The original multiplex image signal is input to the block.

8 isolating an object signal directly from the output of the second switch

9i through block 10 delay. To obtain a single image of operation

the beginning of the frame (fig.Ze). The output of the fourth flip-flop 18 is the first output of the control unit 2. Thus, a start pulse is fed to the third input of the object signal extracting unit 8. The signal of the selected object corresponds to the background figure. The signal from the output of the first trigger 12 times solves the passage through the first element AND 13 XI to the subtracting input of the counter 14. If the contents are equal to zero, the counter 14 produces a pulse (Fig. 3g), including the second trigger 15 (Fig. 3b), which allows the passage XI through the second element AND 16 to the input of the third trigger 17 and through the element OR 11 to the second input of the first trigger 12.

Thus, after the frame after turning on the second trigger 15, the third trigger 17 (FIG. 13) is turned off and the first trigger 12 (FIG. 3b) is turned off. The output of the second trigger 15 is the second output of the control unit 2, therefore, it prohibits the passage of the signal from the output of the quantization unit 3 through the first switch 5 and allows the signal from the output of the first electrolyte to be pressed by pressing the Start button of the control unit 2 to translate the first trigger 12 (FIG. ) in one state and at the same time sets in the counter 14 the number of frames n necessary for the complete selection of the object signal. For the proposed device, njfm, where m is the number of lines in the frame,

Left can not exceed the number of lines in the frame.

Since the output of the first trigger 12 is the third output of the control unit 2, simultaneously passing through the second switch 9 of the signal from the output of memory block 6 and passing the signal from the output of the second element HE 7 is allowed (fig.4b). The inverted signal arrives at the first input of the object extraction unit 8 and through the delay unit 10, delaying the horizontal scanning period, to the second input of the object detection unit 8. The signal from the output of the first trigger 12 is fed to the D-input of the fourth trigger 18, the counting input of which receives XI. This trigger generates a trigger pulse corresponding to .5 0 5

0

the beginning of the frame (fig.Ze). The output of the fourth flip-flop 18 is the first output of the control unit 2. Thus, the trigger pulse is fed to the third input of the object extraction unit 8. The signal of the selected object corresponds to the background figure. The signal from the output of the first trigger 12 permits the passage through the first element AND 13 XI to the subtracting input of counter 14. If the contents are equal to zero, the counter 14 produces a pulse (Fig. 3g), which includes the second trigger 15 (Fig. 3b), which allows the XI to pass through the second element AND 16 to the input of the third trigger 17 and through the element OR 11 to the second input of the first trigger 12.

Thus, after the frame after turning on the second trigger 15, the third trigger 17 (FIG. 13) is turned off and the first trigger 12 (FIG. 3b) is turned off. The output of the second trigger 15 is the second output of the control unit 2, therefore, it prohibits the passage of the signal from the output of the quantization unit 3 through the first switch 5 and permits the passage of the signal from the output of the first eleven1474

HE 4, which forms the inverse signal of the object selected by block 8 (Fig. Ad). The output of the third flip-flop 17 is the fourth output of the control unit 2. Thus, after the frame, after the memory 6 of the inverse signal of the object corresponding to the single-image images arrives at the input, the memory block 6 is transferred to the read mode. The last frame recorded in it is the signal of a single-connected object. Simultaneously, the third output of the control unit 2, associated with the output of the first trigger 12, prohibits the passage of the signal from the second element NOT 7 through the second switch 9 and the passage of the signal from the output of the memory block 6. A signal of monovalent objects is received,. thus, the output of the device for further processing.
