ABSTRACT:
A signal-level calculating unit calculates a signal level based on a gain signal. A sample generating unit associates heater power with the signal level and generates samples used for determining the maximum power. An approximation-line determining unit determines an approximation line of the samples in a two-dimensional coordinate system. A line shifting unit shifts the approximation line and determines a line for determining a signal level when the heater power is increased by one step. A comparative-value calculating unit calculates a comparative value based on the line. An upper-limit determining unit compares the comparative value and an actual signal level, and determines whether the heater power has reached the maximum power.
