Title:
時系列データ圧縮装置
Document Type and Number:
Japanese Patent JP6461029
Kind Code:
B2
Abstract:
A data compressing apparatus includes a polygonal line approximating circuit receiving first time series and outputs second time series by performing a polygonal line approximation process on the first time series. The polygonal line approximating circuit includes a first multiplier and a second multiplier performing multiplication having a first value calculated based on a difference between a time component of first data and a time component of second data in the time series data as input, and a third multiplier and a fourth multiplier performing multiplication having a second value calculated based on a difference between a sensor component of the first data and a sensor component of the second data as input.
