Abstract
Basic data obtained by thinning-out data to be written in a look-up table are previously operated by a computer and stored in a basic memory table. Coefficient data required for linearly interpolating the basic data are stored in a coefficient memory table. The basic data and the coefficient data are read in accordance with address designation by an address generator while being related with each other and subjected to interpolation operation by an interpolation computer element, and data thus obtained are sequentially written in the look-up table.
