PURPOSE: To interpolate input data with a natural feeling by a simple circuit constitution in an interpolation device which interpolates timewisely discreted and successively inputted data and generates interpolated output data. CONSTITUTION: This device is provided with a data input means 101, difference operation means 102 which calculates a difference between a newly inputted data to the data input means 101 and an output data, an adding data operation means 103 which performs filtering processing and coefficient multiplication processing of this difference and successively calculates an adding data for interpolation at each interpolation point at the data input time intervals, and an accumulation means 104 which adds this adding data to the output data and makes a new output data successively, while the filtering processing varies a differential width of the adding data smoothly so that a time-differential value varies smoothly. |
