Zusammenfassung:	PURPOSE: A method for controlling the color temperature of a projector is provided to prevent a projector from being excessively heated by reducing an input current and to easily control the brightness of a primary color light. CONSTITUTION: A method for controlling the color temperature of a projector is as follows. Target values about a mixing light are set(S110). Chromaticity coordinate values of the mixing light, composed of primary color lights, are measured(S120). Target brightness values of the primary color lights are calculated using the target values and the measured values(S130). The outputs outputted from a projector are controlled based on the calculated target brightness values.
