ABSTRACT:
A power supply provides a voltage to a digital camera. If the power supply voltage falls below a predetermined threshold, a voltage sensor generates a signal to a power manager. In response, the power manager configures the camera into a lower power consumption state. As the power source weakens further, the power manager continues to place the camera into a lower and lower power consumption state, until the power source is exhausted. The method of the present invention preferably comprises the steps of monitoring the power source's voltage, generating a signal if that voltage falls below a pre-determined threshold, and reducing the camera's power consumption in response to the signal.
