DATA PROCESSING DEVICE AND DATA PROCESSING METHOD

A data processing device and a data processing method are provided to reduce a characteristic amount extracted from moving picture contents, thereby effectively searching the moving picture contents. A registration moving picture characteristic amount extraction unit(310) extracts a chain point interval from moving picture contents registered by a characteristic amount database(320) as a characteristic amount. An input moving picture characteristic amount extraction unit(330) extracts the chain point interval from moving picture contents input as a search target as the characteristic amount. If the registration moving picture characteristic amount extraction portion extracts the chain point interval of the registration moving picture, an interval list of a chain point interval and contents ID of registered moving pictures are supplied to a DC dictionary registering unit(321) and a CD dictionary registering unit(322) through a signal line(319). When the input moving picture characteristic amount extraction unit extracts the chain point interval of input moving pictures, an interval list of chain point intervals and contents ID of the input moving pictures are supplied to a DC dictionary registering unit(323) and a characteristic amount comparison unit(340) through a signal line(339).
