20140055160 | APPARATUS AND METHOD FOR INSPECTION OF MARKING - An apparatus and method for inspecting whether marking of a target chip in a wafer has been performed normally are provided. The apparatus includes a voltage application detector which detects application of a voltage to an external circuit, an image pickup unit which captures an image, and a controller which controls the image pickup unit to capture an image at at least one predetermined point when the application of the voltage is detected by the voltage application detector and determines whether the marking of the target chip has been performed normally based on the captured image. Accordingly, extra time is not required to inspect whether the marking of the target chip in the wafer has been performed normally and the inspection is performed without using a prober operation program. | 02-27-2014 |

20140097763 | APPARATUS FOR CONTROLLING THE OPERATION OF AN LED, AND METHOD FOR CONTROLLING DRIVE CURRENT THEREOF - The present invention relates to an apparatus for controlling the operation of an LED and to a method for controlling the drive current thereof. More particularly, the present invention relates to an apparatus for controlling the operation of an LED, which is capable of driving a direct current-operated LED module or an alternating current-operated LED module using alternating current power, and to a method for controlling the drive current of the apparatus. According to the present invention, the drive current of an LED array can be output in the form of a sine wave by a constant-current regulation or constant-power regulation even when input voltage varies, thus suppressing harmonics, improving the power factor, minimizing flicker, and preventing a temperature increase in the LED array and in an LED operation control circuit. | 04-10-2014 |

20130237973 | LASER EMISSION SYSTEM AND ROBOT LASER EMISSION DEVICE COMPRISING THE SAME - The present invention discloses a laser emission system comprising a laser emission device for irradiation a laser to an area of a targeted object; a monitoring device; a display unit for displaying an image captured by the monitoring device; and a control unit connected to the monitoring device and the display unit. Here, the control unit receives the information on a movement direction and a moving distance of the laser emission device and distinguishes between an area emitted with a laser by the laser emission device and an area which is not emitted with a laser, and then displays them on the display unit. Regardless of the perceived skill of the operator, the present invention prevents the irradiation of the area from being omitted and prevents the area from being excessively or insufficiently emitted in the laser treatment. | 09-12-2013 |

20100086199 | METHOD AND APPARATUS FOR GENERATING STEREOSCOPIC IMAGE FROM TWO-DIMENSIONAL IMAGE BY USING MESH MAP - Provided are a method and apparatus for generating a stereoscopic image from a two-dimensional (2D) image by using a mesh map and a computer readable recording medium having recorded thereon a computer program for executing the method. Also provided are a method and apparatus for generating a stereoscopic image by reading a 2D image, displaying the 2D image and a mesh map by overlapping the 2D image and the mesh map, and editing mesh shapes and depth information (depth values) of the mesh map by a user, and a computer readable recording medium having recorded thereon a computer program for executing the method. The method of generating a stereoscopic image includes receiving a 2D image; displaying the 2D image and a mesh map by overlapping the 2D image and the mesh map; editing mesh shapes and depth information (depth values) of the mesh map by a user in accordance with shapes of a displayed image; calculating relative depth information of pixels included in the 2D image in accordance with the mesh shapes and the depth information of the edited mesh map; and generating a stereoscopic image file by using the calculated relative depth information of the 2D image. The present invention may be used in a system for generating a stereoscopic image from a 2D image including a general still image or moving picture. | 04-08-2010 |
