Abstract
Current reading means detects an output current of a current source whose output current varies with a variation in temperature and outputs a value proportional to the output current. The temperature of the current source corresponding to the output value of the current reading means which is proportional to the output current of the current source is measured, and a parameter for converting the output value to temperature information is determined from the output value of the current reading means and the measured value of the temperature of the current source corresponding to the output value. The output value of the current reading means is converted to the temperature information using the determined parameter.
