METHOD AND APPARATUS FOR INTERPOLATING DATA IN THE VIDEO PICTURE FIELD

摘要

The present invention relates to a method for interpolating N data from n values (n < N and N/n = p, p being an integer), the n values corresponding to points on a curve which can be linearly approximated, said method comprising the following steps: a) calculating n offset values such as: Offsetk = data (k+1)*p - data k*p with k = 0, 1, 2, ....n, b) storing the n offset values and a start value in a memory, c) interpolating the N data, by calculating: datap*k+a = data p*k + a*offsetk /p where a varies between 1 and p. The invention is mainly applicable to plasma display panel.
