ABSTRACT:
An apparatus for reducing display size whilst substantially maintaining display information content, the display comprising a graph plot of a number of data values, which plot extends in a first direction, each data value having an associated magnitude, the apparatus reducing the extent of the graph plot in the first direction. The apparatus comprises a digital signal processor (1), a data store (3), and a display system (5). The digital signal processor (1) comprises a program sequence unit (7), an arithmetic unit (9), and an address generator unit (11). The processor (1) divides up the data values into a series of groups of five adjacent data values each, selects from each group two data values having predetermined positions within that group for the purpose of preserving the presence in the graph plot of these two selected data values, and discards one of the three not selected data values from each group in dependence on the relative magnitudes of these three data values. The data store (3) stores the data values prior to the discarding of data values and the data values remaining after the discarding of data values. The display system (5) compresses in the first direction the graph plot of the remaining not discarded data values.
