1. An apparatus for controlling the temperature of a heater provided in a liquid crystal element,
wherein the apparatus 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 detect current consumption flowing through the partial region, and
wherein the apparatus is configured to variably set a temperature control target value of the heater according to a detected magnitude of the current consumption.
