Endoscope apparatus, endoscope, initialization method, and initialization program

The present invention relates to an electronic apparatus and a power supply controlling method with which input power source is switched efficiently in accordance with a load of a device. A power controller, upon detecting a USB connection, monitors power consumption of a CPUbased on the operation status of the CPU, and controls a switchin accordance with a current supplied from a USB cable. When the current is less than or equal to 500 mA, the switchis switched to a terminal a. Before configuration, when the current is less than or equal to 100 mA, the switchis switched to the terminal a, and then a regulatoris controlled so that the current will not exceed 100 mA. In USB suspend, the switchis switched to a terminal b, and a regulatorstops output to a backup battery. The present invention can be applied to a digital still camera supporting USB.
