Title:
DATA INTERPOLATING DEVICE
Document Type and Number:
Japanese Patent JP3728759
Kind Code:
B2
Abstract:

PURPOSE: To provide a data interpolating device with which the number of times of calculation of a filter coefficient is decreased.
CONSTITUTION: A data selecting part 1 selects the combination of a first-term output point and an input point to share the filter coefficient out of input points required for calculating respective output points. A filter coefficient calculating part 2 calculates the filter coefficient to be commonly used. A filter arithmetic part 3 performs filtering processing to the combination of the input point and output point supplied from the data selecting part 1 by using the filter coefficient to be commonly used. Thus, the number of times of calculation of the filter coefficient is decreased.
