IPC: G01R13/22
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To prevent the lack of information and prevent a signal waveform from being not reproduced on a picture image faithfully even if data is thinned out when a picture image represented by less number of sampling points is formed by using many sampling data which sample signal waveforms. SOLUTION: Sampling data (a) to (r) is divided into partial row a to c, d to g, h to k,..., and line picture image data which connects the maximum value and the minimum value in each partial row is arranged in the direction of time axis to form picture image data which represents signal waveforms. When the line picture image data is determined, all amplitude values in each partial row are taken into considerations, and the information that each amplitude value existed is left. That is, the line picture image data represents the whole scope of fluctuation of the amplitude values in each partial row, and the picture image data which is obtained in this way reproduces an outline of the signal waveforms with precision.
