20100012186 | Bulb-Type Light Concentrated Solar Cell Module - Provided is a bulb-type light concentrated solar cell module that includes a reflective mirror unit that is concavely formed to convergingly reflect sunlight and has a first hole on a bottom thereof; a solar cell that generates electrical energy in response to light received from the reflective mirror unit; a socket that blocks the first hole at a lower part of the reflective mirror unit and is fixed on the reflective mirror unit; and a power control unit that is electrically connected to the solar cell to generate electricity in the socket. | 01-21-2010 |
20120161159 | Method of manufacturing silicon optoelectronic device,silicon optoelectronic device manufactured by the method, and image input and/or output apparatus using the silicon optoelectronic device - A method of manufacturing a silicon optoelectronic device, a silicon optoelectronic device manufactured by the method, and an image input and/or output apparatus including the silicon optoelectronic device are provided. The method includes preparing an n- or p-type silicon-based substrate, forming a microdefect pattern along a surface of the substrate by etching, forming a control film with an opening on the microdefect pattern, and forming a doping region on the surface of the substrate having the microdefect pattern in such a way that a predetermined dopant of the opposite type to the substrate is injected onto the substrate through the opening of the control film to be doped to a depth so that a photoelectric conversion effect leading to light emission and/or reception by quantum confinement effect in the p-n junction occurs. The silicon optoelectronic device has superior light-emitting efficiency, can be used as at least one of a light-emitting device and a light-receiving device, and has high wavelength selectivity. In addition, the silicon optoelectronic device panel having the two-dimensional array of the silicon optoelectronic devices can be applied in the image input and/or output apparatus capable of directly displaying an image and/or inputting optical information in a screen. | 06-28-2012 |
20120242975 | DEPTH SENSORS, DEPTH INFORMATION ERROR COMPENSATION METHODS THEREOF, AND SIGNAL PROCESSING SYSTEMS HAVING THE DEPTH SENSORS - According to at least one example embodiment, a depth information error compensation method includes outputting modulated light to a target object, detecting a plurality of first pixel signals at different detection time points in a first time interval, the first pixel signals representing light reflected from the target object during the first time interval, detecting a plurality of second pixel signals at different detection time points in a second time interval, the second pixel signals representing light reflected from the target object during the second time interval, comparing each of the plurality of first pixel signals with each of the plurality of second pixel signals and calculating depth information to the target object according to the comparing. | 09-27-2012 |
20140062864 | METHOD AND APPARATUS FOR EXTRACTING THREE-DIMENSIONAL DISTANCE INFORMATION FROM RECOGNITION TARGET - A method and apparatus for extracting three-dimensional distance information from a recognition target is provided, which enables a gesture input from a user to be correctly recognized using distance information from the recognition target, and at the same time makes it possible to efficiently save power required for detection of the gesture input. The method includes determining if a recognition target exists within a predetermined range; when the recognition target exists within the predetermined range, generating a 3D image for the recognition target; and calculating a distance to the recognition target by using the 3D image. | 03-06-2014 |
20140078311 | METHOD FOR GUIDING CONTROLLER TO MOVE TO WITHIN RECOGNIZABLE RANGE OF MULTIMEDIA APPARATUS, THE MULTIMEDIA APPARATUS, AND TARGET TRACKING APPARATUS THEREOF - Methods, systems, and devices for guiding a subject back within the recognizable visual range of a multimedia system are described. According to one of the described methods, when it is determined that the target has left the recognizable range of the multimedia system, sensor information is acquired from a portable electronic device (or controller) the user has been using to control the multimedia system, and the acquired sensor information is used to determine where the user is, relative to the recognizable range. In one example, the user is asked to make a gesture with the portable electronic device, and the sensor information concerning that gesture is used to determine the user's relative location. In another example, the sensor information recorded at the time the user left the recognizable range is used to determine the user's relative location. | 03-20-2014 |
20140096084 | APPARATUS AND METHOD FOR CONTROLLING USER INTERFACE TO SELECT OBJECT WITHIN IMAGE AND IMAGE INPUT DEVICE - A method for controlling a user interface of an apparatus to enable intuitive manipulation for an object included in an image is provided. An object with deeper depth in a rear image of the apparatus may become selectable when the user holds a user input means close to the apparatus, while an object with shallower depth in the rear image may become selectable when the user draws the user input means away from the apparatus, thereby allowing the user to intuitively select an object in the rear image. | 04-03-2014 |
20140341428 | APPARATUS AND METHOD FOR RECOGNIZING HUMAN BODY IN HYBRID MANNER - An apparatus and a method for recognizing a human body in a hybrid manner are provided. The method includes calculating body information used for recognizing a human body from an input image, detecting a region of the human body in a learning-based human body recognition manner by using the calculated body information, and tracing a movement of the detected region of the human body in a modeling-based human body recognition manner. Thereby, it is possible to quickly perform more accurate and precise recognition of the human body. | 11-20-2014 |
20140355830 | METHOD AND APPARATUS FOR PROTECTING EYESIGHT - A method and an apparatus for controlling a display in order to secure an appropriate viewing distance between a digital device and a user who is viewing the digital device is provided. Accordingly, the method determines whether an object exists within a hazardous viewing distance using a 3D camera function provided in the digital device. If it is determined that an object exists within the hazardous viewing distance, the digital device detects a face or eyes from 2D images photographed by the camera. Next, the direction of the face is determined on the basis of the detected results, and it is determined whether a user is viewing a display screen of the digital device based on the determination. If it is determined that a user is viewing a display screen of a digital device, the digital device generates a warning that the user is positioned within a hazardous viewing distance. | 12-04-2014 |
