Abstract
An apparatus for controlling the temperature of a heater provided in a liquid crystal element is configured to apply a drive voltage which is set to a value relatively higher than when the liquid crystal element is operated at a rated voltage value and/or a rated frequency, to at least a partial region of the liquid crystal element, and detects current consumption flowing through the partial region. The apparatus variably sets a temperature control target value of the heater according to the detected magnitude of the current consumption.
