Abstract

PURPOSE: To facilitate macroscopic and perceptive measurement by extracting a moving (fluctuating) component signal from a picture signal, emphasizing the moving component signal with shading and the like, and indicating the same together with the picture signal in an overlapping manner.

CONSTITUTION: A picture input circuit 1 is a circuit inputting the picture at a sampling cycle necessary for measuring the vibration of a substance to be measured. The output of the picture input circuit 1 is given to a fluctuation detecting circuit 2 and subjected to sampling and only a fluctuating part between the pictures coming in time series is detected and taken out. At this time, a fluctuating picture is obtained, and on the occasion, the fluctuating picture of a part whose fluctuation is large turns to be large and the area of fluctuation of a part whose fluctuation is small turns to be small, while the fluctuating picture of a part which shows no fluctuation turns to be zero. And, the fluctuation picture thus obtained has informations on the distribution and size (amplitude) of fluctuation thereof. This flucutating picture and the output of the picture input circuit 1 are given to a overlapping circuit 3 and thence to an indicating circuit and thereby the part of the output picture of the input circuit 1 and the part of the fluctuating picture turn possible to be discriminated clearly from each other.
