Abstract: When a three-dimensional image of a specific subject is acquired by means of an infrared camera and an external light (for example, external light such as sunlight at the time of outdoor photography) having a relatively large intensity exists, it is difficult to acquire the image. To this end, the present invention proposes an electronic device for reducing a current peak by adaptively changing optical power and an exposure time of an infrared camera according to the intensity of external light.

Abstract: An apparatus and a method for controlling an electronic device are provided. The electronic device includes a housing, a holder positioned in a first surface of the housing to mount an external electronic device thereon, a beam projector positioned in a second surface of the housing, a mirror positioned between the first surface and the second surface to reflect a content outputted from the beam projector, an input unit provided in the housing, a transceiver communicable with the external electronic device, and a processor. The processor is configured to control for receiving the content from the external electronic device, outputting the content using the beam projector, and adjusting a direction in which the mirror is positioned according to a rotation control signal on the mirror received from the external electronic device through the transceiver or received through the input unit to adjust a direction in which the content is reflected.

Abstract: A scheduling method in a distributed antenna system is provided. Each of a plurality of Mobile Stations (MSs), respectively corresponding to each subchannel, are classified as a Single Transmission (ST) MS or a Cooperative Transmission (CT) MS according to a CT criterion. An MS with a maximum channel capacity is selected from among the classified MSs. Resources are allocated to a corresponding subchannel when the selected MS is the ST MS, and resources are allocated using a CT scheduling technique when the selected MS is the CT MS. The classifying, selecting and allocating steps are repeated until allocation of resources is completed.

Abstract: A method for scheduling in a cellular system using a relay station (RS) through an inter-antenna cooperative transmission technology based on pre-cooperation information according to each channel in a cellular system using a cable RS in order to increase the throughput of the entire system. The steps include classifying all mobile stations (MSs) in a corresponding cell based into Cooperative Transmission (CT) MSs for cooperative transmission and Single Transmission (ST) MSs for to each channel; mapping channel-by-channel channel capacities of the CT MSs and ST MSs classified according to each channel, selecting a channel with a highest priority, and receiving a request message from a corresponding MS according to whether the capacity of the selected channel satisfies preset CT criteria and selecting an MS having a metric value of a highest priority according to a corresponding scheduling algorithm, from among multiple requesting MSs.
