ELECTRONIC APPARATUS, METHOD FOR CONTROLLING ELECTRONIC APPARATUS, COMPUTER PROGRAM, AND RECORDING MEDIUM

摘要

The present invention provides an electronic device that can operate as long as possible even if the battery level is low and that can avoid an unexpected shutdown as much of the time as possible while data is being transmitted to, or received from, an external device. The electronic device has a particular mode of operation in which the electronic device is connected to an external device and can accept a request to read and/or write information sent by the external device. The electronic device includes: a battery; an interface, which is connected to the external device so as to get power from the external device and which accepts the request sent by the external device; and a control section for changing conditions for enabling that particular mode of operation according to a supply value, which is at least one of the values of current and voltage supplied by the external device, and a value representing a level of the battery.
