The device for filtering the images of the mobile microbiological objects contains the source of illumination and microscope. The sample is examined in Petri dish with nutrient medium. The uniform temperature in Petri dish is maintained with the aid of thermostatic device. The microscope is connected to television set. The device also contains the recording unit, the generator of timing pulses, the time-delay element, the first and the second memory storage units, the subtracting unit. The first output of TV sensor is connected to the input of the first memory storage unit, the second output of TV sensor is connected with the first input of the time-delay element. The second input of the time-delay element represents the first output of the generator of timing pulses with its second output connected to the second input of TV sensor. |
