Abstract
A lookup table device is provided which converts a digital input signal into a digital output signal previously defined with respect to the digital input signal. The lookup table device has a delimiter information storage unit 10 for storing delimiter information representing a delimiter in a section of the digital input signal corresponding to the digital output signal, a section deriving unit 12 for deriving a section to which a digital input signal belongs, based on the delimiter information stored in the delimiter information storage unit, when the digital input signal is inputted into the lookup table device, and a signal output unit 14 for outputting a digital output signal corresponding to the section derived by the section deriving unit.
