1. A method for displaying a high-resolution distribution of physical parameters in form of pressures or forces acting at right angles on a stage having a matrix of sensors, comprising the steps:
- measuring said parameters with said sensors having an electrical output signal, said parameters being displayed on a display monitor;
converting said output signal to digital values when said output signal is an analog signal;
storing digital values of each sensor in a respective address in a results memory;
generating from the digital values stored in the results memory a first virtual image in form of a matrix of squares with sides of a first predetermined length and representing locations of said sensors, each stored digital value being associated with pixel values from a pixel memory;
generating from the pixel values a second virtual image in form of a matrix of squares with sides of a second predetermined length differing from said first predetermined length, one virtual image being superimposed on the other virtual image;
calculating each pixel value by a processor from a square area surrounding centrally said pixel value in said second virtual image by determining each area in said first virtual image;
weighting each area with stored digital value in said first virtual image by forming products with areas of surrounding squares and summing all products;
summing all areas of said surrounding squares;
dividing the sum of all products by the sum of all areas of said surrounding squares and forming a quotient;
storing the quotient in a corresponding address in said pixel memory; and
displaying contents of said pixel memory on said display monitor.
