ABSTRACT:
A digital convergence apparatus detects the presence/absence, frequency and the number of scanning lines of inputted synchronizing signals, performs an interpolation between adjusting points corresponding to the detection signal to prepare a correction data, and performs a cursor display of a center position between adjusting points, extrapolating operation control and difference data storage, writing of the same data into n-planes, and time sharing the interpolation processor so as to accommodate multimedia with a high accuracy.
