Abstract:
A data storage device comprising;time-series data input means for inputting time-series data containing at least one of audio data and image data, wherein the time-series data is input during both important intervals and other intervals;time-series data storing means for storing time-series data input from the time-series data input means;user input means for inputting user-input data,user-input data detection means for detecting user-input data input from the user input means, wherein the detected user-input data is used to designate an important interval;correspondence relationship storing means for storing a correspondence relationship between at least the user-input data and a position in the time-series data storing means where the time-series data corresponding to the important interval is stored;a condition-matching interval detection means for detecting a condition-matching interval in which the time-series data matches a predetermined condition unique to an event;compression means for compressing the time-series data which is stored in the time-series data storing means, wherein the time-series data corresponding to an important interval is compressed differently than the time-series data corresponding to the other intervals.
