Abstract:
An apparatus and methods for recognizing an image with an increased image recognition rate are provided. The apparatus includes a plurality of illuminators for illuminating a surface. The apparatus also includes an image sensor for outputting an image frame obtained by converting an optical image of the surface into an electrical signal. The surface is illuminated one of the plurality of illuminators. The apparatus further includes a switch for selecting any of the plurality of illuminators for illuminating the surface. The apparatus additionally includes a controller for receiving the image frame from the image sensor, determining whether the image frame has a region of reflected light, and controlling the switch to select another of the plurality of illuminators to illuminate the surface when the image frame has the region of reflected light.
Abstract:
Apparatuses and methods which provide synchronized data using visible light communication are described. In one method, a first Light Emitting Diode (LED) lighting apparatus, which has a checked Identification (ID), receives a synchronization signal from a mobile communication network. This synchronization signal is analyzed in order to synchronize the first LED lighting apparatus with at least one second LED lighting apparatus adjacent to the first LED lighting apparatus. A synchronized time slot is prepared using the synchronization signal and a period of the time slot is determined, using the checked ID of the first LED apparatus, for transmitting data of the first LED lighting apparatus to a mobile terminal.

Abstract:
A method and an apparatus acting as a server for estimating parameters of data transfer across a communication network are provided. The server includes a transceiver which enables data transfer operations and an estimator which estimates throughput as one of the parameters of the data transfer operations. The estimator further determines an indicator value of the throughput corresponding to an estimated bottleneck bandwidth (eBnBW) calculated from data traffic measurements. The indicator value is attributable to and indicates optimal parameters of the data transfer operations, calculated from measurements associated with the data traffic. The server apparatus includes a processor, in communication with the transceiver and the estimator, and the processor is configured to control for preparing succeeding data transfer operations to a client apparatus through the communication network based on the estimated bottleneck bandwidth determined by the estimator.
Abstract:
A display apparatus is provided that includes a plurality of color filters corresponding to subpixels forming pixels of the display apparatus, and a black matrix formed among the plurality of color filters. The plurality of color filters includes a pattern indicating an absolute location of each pixel of the display apparatus.
