An electronic device comprises a body and a band being able to attach the body to a part of a human body. The body comprises first and second detectors and at least one processor. The first detector detects illuminance on an upper surface of the body. The second detector is located in a position distant from a position of the first detector in a short-side direction of the band and detects the illuminance on the upper surface of the body. The at least one processor executes predetermined processing if the at least one processor determines that at least one of first illuminance detected by the first detector and second illuminance detected by the second detector changes.

This invention is a wrist-worn device with at least one camera on a movable component that flips-up or pops-up from a wrist band or sleeve. It can be embodied in a smart watch. In an example, there can be two cameras on the flip-up or pop-up component, one that faces toward a person wearing the device and one which faces away from the person wearing the device. The angle of the movable component and the focal direction of a camera can be adjustably locked by the person into different positions.

A method for updating images displayed on an electronic display of a mobile device includes determining a time interval between successive updates of an image frame. The image frame is displayed on the electronic display, and the mobile device is configured to be in a low power mode between the successive updates. The method also includes receiving one or more application updates within the time interval after a first update of the image frame, and updating the image frame after the time interval based on the one or more application updates.

There is provided a wearable device comprising at least one processor; and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the wearable device at least to perform: obtaining a starting time of a latest sleeping period; obtaining an ending time of the latest sleeping period; displaying, on a display of the wearable device, a first line illustrating an average starting time of a sleeping period calculated based on a plurality of sleeping periods over a plurality of days; displaying a second line illustrating an average ending time of a sleeping period calculated based on the plurality of sleeping periods over the plurality of days; and displaying the latest sleeping period graphically as a bar such that a first end of the bar indicates the starting time and a second end of the bar indicates the ending time, wherein the first end and the second end are displayed relative to the first line and the second line, and wherein a length of the bar indicates a length of the latest sleeping period.

A wearable device includes a multi-use circuit that includes a terminal provided so as be able to be close to a subject and that is capable of being used for both (i) a determination function that determines whether the wearable device is being worn on the subject and (ii) a predetermined function other than the determination function, and a processor configured to execute the determination function.

An imaging device includes a lens that guides, to an imaging element, light reflected from a subject, a wearing tool for wearing at least the lens on a wearing target, and at least one processor. The processor determines whether a first condition based on a positional relationship of the lens with respect to the wearing target is satisfied, determines whether a second condition that includes a condition based on the positional relationship of the lens with respect to the wearing target is satisfied, the second condition differing from the first condition, and makes an imaging parameter of at least one of the imaging element or the lens for when the first condition is satisfied and for when the second condition is satisfied different from each other.

A device for monitoring athletic performance of a user has a wristband configured to be worn by the user. An electronic module is removably attached to the wristband. The electronic module has a controller and a screen and a plurality of user inputs operably associated with the controller.

An operating device may include an operating element that is axially moveable about an axis of rotation, and a display unit arranged radially inside the operating element with respect to the axis of rotation and stationary with respect to the operating element. The display unit may be at least partially surrounded by the operating element. A control unit may control the display unit such that at least one selection region is displayed, which can be selected based on a displacement of the operating element. When a selection region is selected using the operating element, an operating function currently associated with the selection region is triggered. The operating device supports intuitive operation based on the immediate proximity of the operating element to the display unit.

A watch-type mobile terminal including a display; a bezel forming a rim of the display and including a touch sensor; a crown; and a controller configured to display first content on the display, sense a rotation input on at least one of the crown and the bezel when the first content is displayed on the display, and display second content associated with the first content on the display in response to the rotation input.

An electronic device is communicatively connected to an electronic terminal configured to display an output value of a sensor. The electronic device includes a storage unit and a processor. The storage unit is stores a first city to be set in the electronic terminal. The processor fixes or changes a display-unit of the output value of the sensor to be displayed on the electronic terminal, based on the first city and a display language set in an OS of the electronic device.
