Abstract
A power control apparatus for an in-vehicle camera includes a temperature sensor which measures the temperature in a camera unit; a temperature data acquisition section which acquires periodically measured temperature data; a predicted temperature calculation section which calculates a temperature gradient from the acquired temperature data group and, based on the temperature gradient, calculates a future predicted camera unit temperature; a power supply section which supplies power to an image processing section; a temperature determination section which determines whether predicted temperature is within an operation guarantee temperature of camera unit component parts; and a power supply control section which, based on a determination result, issues a control command to start or stop power supply to the component parts from the power supply section, the power supply being started or stopped with appropriate timing using the predicted temperature, thereby enabling expeditious protection of the component parts when at high temperature.
