Abstract: An electronic apparatus is disclosed. A display is configured to be able to change brightness of the display. A water detector is configured to detect water. A communication unit is configured to be able to communicate with another electronic apparatus. At least one processor is configured to, when the at least one processor detects, using the water detector, that at least part of the electronic apparatus is located in the water and detects, using the communication unit, that the another electronic apparatus is not located in the water, brighten the display compared with that when the at least one processor detects, using the water detector, that the at least the part of the electronic apparatus is located in the water and at least part of the another electronic apparatus is located in the water.

Abstract: An electronic apparatus, an electronic apparatus system, and a method for controlling an electronic apparatus are disclosed. An electronic apparatus communicates with an input apparatus worn on an operator body part being a part of a body of a user. The input apparatus includes a motion detector. The motion detector is configured to detect motion information indicative of a movement of the operator body part. The electronic apparatus includes a display and at least one processor. The at least one processor is configured to perform a luminance control in which a luminance of the display is controlled according to an inclination of a virtual input surface. The virtual input surface is a first surface on which a trace of the operator body part based on the motion information is drawn or a second surface parallel to the first surface.

Abstract: An underwater sensor is configured to detect an underwater state in which at least part of an exterior of the electronic apparatus is located in the water and an above-water state in which the at least part of the exterior is not located in the water. An acceleration sensor is configured to detect acceleration. An image sensor includes a transparent member located in the exterior and is configured to receive light entering through the transparent member and generate a captured image. At least one processor is configured to identify a water surface image among a plurality of captured images generated by the image sensor, based on the acceleration and a transition timing at which one of the underwater state and the above-water state changes to the other state, the water surface image being captured when the transparent member reaches a water surface.

Abstract: A mobile phone, a method for operating a mobile phone, and a recording medium are disclosed. In one embodiment, a mobile phone comprises a wireless communicator, a proximity detector, and at least one processor. The wireless communicator is configured to receive information from an input apparatus external to the mobile phone. The proximity detector is configured to detect an object in proximity. The at least one processor is configured to perform a voice call with a first phone apparatus external to the mobile phone and activate an input from the input apparatus when the proximity detector detects the object in proximity and the at least one processor performs the voice call.

Abstract: According to an aspect, a device includes a touch screen display and a controller. The touch screen display displays a lock screen provided with a display area in which any of a plurality of icons is displayed. The controller displays any of the icons in the display area according to a first touch gesture detected through the touch screen display while the lock screen is displayed.

Abstract: In one aspect, when detecting an event such as receiving emails, missed calls, a schedule notification, or the like, a mobile electronic device executes a process for expanding a first operation part associated with the event on a display module and displaying a second operation part indicating a detail of the event within the expanded first operation part. For example, upon detecting an operation applied onto the first operation part via the touch screen, the mobile electronic device executes a process associated with the first operation part, and upon detecting an operation applied onto the second operation part, the mobile electronic device executes a process associated with the second operation part.
