Abstract: An endoscope apparatus includes: a camera head configured to examine an interior of a subject and output a result of the examination; and a control apparatus electrically connected to the camera head and configured for the examination result to be inputted thereto from the camera head and to control operation of the camera head. The camera head includes a plurality of devices, and a CPU configured to perform initialization of at least one of the plurality of devices. The endoscope apparatus makes it possible to shorten start-up time of the entire endoscope apparatus.

Abstract: 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 50, upon detecting a USB connection, monitors power consumption of a CPU 44 based on the operation status of the CPU 44, and controls a switch 42 in accordance with a current supplied from a USB cable 2. When the current is less than or equal to 500 mA, the switch 42 is switched to a terminal a. Before configuration, when the current is less than or equal to 100 mA, the switch 42 is switched to the terminal a, and then a regulator 43 is controlled so that the current will not exceed 100 mA. In USB suspend, the switch 42 is switched to a terminal b, and a regulator 53 stops output to a backup battery 54. The present invention can be applied to a digital still camera supporting USB.
