Abstract
A data processing apparatus includes: a data input section for receiving input of a plurality discrete data arranged at predetermined time intervals; a first-derivative adding section for adding a first derivative to each input discrete data; using a plurality of the discrete data with the additional first derivative, when a difference between one or a plurality of discrete data interposed between two discrete data and a value on a curve passing through the two discrete data points generated on the basis of the two discrete data, the first derivative, and time interval information of the two discrete data is within an allowable error, a homogeneity/heterogeneity conversion section for obtaining a plurality of discrete data having heterogeneous time intervals and the additional first derivative by thinning one or a plurality of the discrete data interposed between the two discrete data; and a heterogeneous-data generation section for generating the heterogeneous data.
