Abstract: To avoid unintentionally turning off a backlight, a device includes circuitry that is configured to control a backlight to illuminate a display panel of the device; store a first preset time interval for reducing brightness of the backlight; determine that an input has not been received within the first preset time interval; acquire one or more signals from a sensor device corresponding to movement of the device; estimate whether the device is in use based on the one or more signals; and postpone a reduction in the brightness of the backlight based when a result of an estimate indicates that the device is in use.

Abstract: Discussed herein is an information processing device that displays information in an effective manner on a display screen of the device. A portion of the total data is displayed on the screen when the total data exceeds the amount of data that can be displayed on the screen at a given time. The information processing apparatus characterizes the potions of data as already-read data portions and unread data portions, based on a speed of a scrolling operation performed when the corresponding data portion is displayed on the device. Further, the apparatus also provides a visual indication for each already-read data portion on the display screen of the device. Thus, a user can correctly identify data portions that have been already read and data portions that are yet to be read.

Abstract: There is provided a communication terminal including an acquisition unit that acquires, from another communication terminal, meta-information associated with content stored in the other communication terminal, and a playlist management unit that manages a playlist which is shared with the other communication terminal and which is for playing back content corresponding to the meta-information acquired from the other communication terminal.

Abstract: There is provided a communication terminal including an information acquisition unit that acquires, from another communication terminal, first information that includes connection information for connecting to a communication service and identification information of a user of the other communication terminal, and an information generation unit that, on the basis of the first information acquired by the information acquisition unit, generates second information that includes the connection information and identification information of a user of the current terminal.

Abstract: There is provided an image processing device including a person recognition unit that recognizes a person included in each of a plurality of captured images, an image evaluation unit that evaluates one or more captured image groups extracted from among the plurality of captured images, on the basis of a degree of appearance for each person of interest recognized by the person recognition unit, and an image selection unit that selects a captured image group having the highest result of the evaluation by the image evaluation unit.

Abstract: There is provided a communication terminal including an acquisition unit that acquires service identification information associated with a communication service from an information processing device that manages shared content, a user identification information issuing unit that issues service user identification information associated with the service identification information to another communication terminal, and a transmission control unit that causes a communication unit to transmit the service identification information, and the service user identification information issued by the user identification information issuing unit to the information processing device.
