Title:
Apparatus and method for generating time-series data, apparatus and method for editing curves and recording medium having program recorded thereon
Abstract:
An apparatus and a method for generating time-series data, an apparatus and a method for editing curves and a recording medium having a recorded program in which the corresponding relation between curves at different time junctures is obtained from given corresponding points such as to prevent the curve shape from becoming dull due to smoothing. A candidate point string extraction unit checks the relation between the input point coordinate and the corresponding relation information to set each group of input points having the corresponding relation as a corresponding point string. An interpolation curve generating unit calculates an interpolation curve C(t) interpolating the corresponding point string along the time axis. An extraction time juncture extraction unit extracts the extraction time junctures ts of the corresponding point string for which the corresponding points are not acquired and calculates the curve I2(t) at the extraction time junctures ts and the passage position C(ts) of the interpolation curve I2(ts). The corresponding point calculating unit 105 calculates the corresponding point P(ts) at the extraction time juncture ts from the curve I2(t) and the passage position C(ts) of the interpolation curve I2(ts). A curve editing device is also provided by employing this time-series data generating device.
