Abstract:
1. A data converting device comprising a data converting unit configured to sequentially convert first data obtained by quantization with a first number of bits to second data extended to a second number of bits, the first data and the second data being data that can assume respective maximum values thereof, wherein when a value of the first data is the maximum value, the data converting unit converts the first data to the second data such that the second data is set to a value that takes into account the value of first data that precedes or succeeds the first data being converted, wherein the second number of bits is greater than the first number of bits, wherein when the value of first data pertaining to a present conversion is the maximum value and the value of first data pertaining to a last conversion is not the maximum value, the data converting unit performs the present conversion such that the second data is set to a value between a value of the second number of bits that is obtained by adding zeros on a lower-bit side of the maximum value and the maximum value of the second data.
