Abstract:
1. A time-series data recording device for recording time-series data, comprising: a control unit including a first characteristic detecting unit detecting a first characteristic from said time-series data, a temporary storage unit storing and updating a first time point representing occurrence of the first characteristic when the first characteristic is detected by said first characteristic detecting unit; a second characteristic detecting unit detecting a second characteristic; a first recording unit automatically recording, upon detection of the second characteristic, the time-series data after a second time point representing detection of the second characteristic; and a second recording unit retroactively recording automatically, upon detection of the second characteristic, the time-series data between the first time point and the second time point, wherein said first characteristic is a candidate starting time point for starting recordation of time-series data, and wherein said second characteristic is an actual starting time point for starting recordation of time-series data.
