<p>A temperature data coding unit 100 increases the data resolution in a high temperature range and reduces the data resolution in a low temperature range, and makes the data length of the temperature data a fixed length. When carrying out numerical estimation of the fixed length code value in terms of a 2's complement numerical code value, the temperature data coding unit 100 generates coded data that increases with an increase of the pre-coded temperature data in terms of the 2's complement numerical code value.</p> |
