1. A power control apparatus for an in-vehicle camera, characterized by comprising:
a temperature sensor which is installed inside a camera equipment of an in-vehicle camera and which measures the temperature of the camera equipment;
a temperature data acquisition circuitry which periodically acquires temperature data from the temperature sensor;
a predicted temperature calculation circuitry which, based on the temperature data, calculates a future predicted temperature of the camera equipment;
a power supply circuitry which supplies power to component parts configuring the camera equipment;
a temperature determination circuitry which determines whether or not the predicted temperature is within an operation guarantee temperature of the component parts; and
a power supply control circuitry which, based on a result of the determination of the temperature determination circuitry, issues a control command to start or stop the power supply to the component parts from the power supply circuitry.
