摘要： A dual-port broadband light source is disclosed. In the dual-port broadband light source, a first beam splitter splits a first ASE at a first ratio into the second and third light paths and outputs the first ASE received from the second light path to the first light path. A second beam splitter splits a second ASE at a second ratio into the second and fourth light sources and outputs the second ASE received from the second light path to the first light path. A first reflector reflects input first and second ASEs in the first light path, and a second reflector reflects input first and second ASEs in the second light path. A first gain medium generates the first ASE between the first reflector and the first beam splitter, and a second gain medium generates the second ASE between the first reflector and the second beam splitter.

摘要： Disclosed are an apparatus and a method for text recognition capability using a camera provided in a mobile communication terminal. Image pre-processing discriminates a text color and a text-background color in an input image, and unifies regions except the text into the text-background color, so that a text region and a background region surrounding the text region can be precisely separated. The image pre-processing method is adaptive to a photographing environment, whereby stable text recognition capability can be expected even if the photographing environment is variously changed.

摘要： Disclosed is a method and an apparatus for recognizing characters using an image. A camera is activated according to a character recognition request and a preview mode is set for displaying an image photographed through the camera in real time. An auto focus of the camera is controlled and an image having a predetermined level of clarity is obtained for character recognition from the images obtained in the preview mode. The image for character recognition is character-recognition-processed so as to extract recognition result data. A final recognition character row is drawn that excludes non-character data from the recognition result data. A first word is combined including at least one character of the final recognition character row and a predetermined maximum number of characters. A dictionary database that stores dictionary information on various languages using the first word is searched, so as to provide the user with the corresponding word.

摘要： Disclosed is a self-healing apparatus and method of an optical receiver that is capable of avoiding error due to temperature variation in the optical receiver when determining the bit rate. The apparatus includes an optoelectric converting unit for converting an input optical signal into an electrical signal; an amplifying unit for amplifying the electrical signal outputted from the optoelectric converting unit; a bit rate discriminating unit for exclusively OR'ing the electrical signal with a delay signal that is delayed from the amplified receiving signal by a predetermined time, thereby outputting a recognition signal; a clock/data reproducing unit for receiving the electrical signal, and for reproducing clocks and data based on a reference clock; a bit rate signal generating unit for generating the reference clock in response to a bit rate change signal; a temperature sensing unit for outputting a temperature sensing signal that is indicative of the internal temperature of the optical receiver; and, a control unit for determining the bit rate of the receiving signal based on a value selected from temperature-dependent voltage level variation values that are previously stored, on the basis of the voltage level of the recognition signal outputted from the bit rate discriminating unit and the internal temperature of the optical receiver corresponding to the temperature sensing signal, and for outputting the bit rate change signal based on the determined bit rate.
