20100023625 | TERMINAL UNIT FOR HANDLING SESSION ON THE BASIS OF SESSION INITIATION PROTOCOL, METHOD OF TRANSMITTING AND RECEIVING THEREOF - According to the present invention, a service is configured by a plurality of sessions and respective session negotiation requests defined by different media formats can be performed without influencing existing connected sessions, and hence it is easy to add, delete, and change the media, the contact of session negotiation can be specified, and the response to the session negotiation request can be processed easily with the service acceptance or rejection of the contact. | 01-28-2010 |
20100277478 | Image processing apparatus and method - A selector of an image processing apparatus may select, from a plurality of sub-pixels included in a first pixel, at least one sub-pixel to be anti-aliased. A processor of the image processing apparatus may calculate a color value of the first pixel by performing an anti-aliasing process with respect to each of the selected at least one sub-pixel. | 11-04-2010 |
20110187714 | IMAGE PROCESSING APPARATUS AND METHOD OF RENDERING USING A RAY TRACING SCHEME - Provided is an image processing apparatus. Ray tracing may be performed using a general scheme with respect to a plurality of reference pixels among pixels of an image to be rendered. With respect to a pixel excluding the reference pixels, geometry information may be interpolated based on a ray tracing result of adjacent reference pixels. | 08-04-2011 |
20120069021 | Apparatus and method of early pixel discarding in graphic processing unit - A method to discard pixels early includes a first early depth test maintaining a depth value on a pixel to be discarded by a discard instruction, and a second early depth test updating the depth value on a pixel not to be discarded by the discard instruction. Because of the first and second early depth tests, a number of pixels to be processed by a pixel shading process may be reduced. | 03-22-2012 |
20120075287 | Image processing apparatus and method - Provided is an image processing apparatus. The image processing apparatus may perform an intersection test for rendering of a ray tracing scheme. The image processing apparatus may include a first calculator and a second calculator. The first calculator may perform a ray-plane test to determine whether a ray intersects a plane including a primitive and a barycentric test to determine whether the ray intersects the primitive. The second calculator may calculate a hit point based on the ray which intersects the primitive. | 03-29-2012 |
20120075288 | Apparatus and method for back-face culling using frame coherence - Disclosed are an apparatus and a method for back-face culling using coherence between chronologically adjacent frames. The apparatus and the method determine whether face properties of polygons are changed based on a matrix reflecting three-dimensional motion of a frame. When the face properties are not changed, face properties of the polygons used in a process of a previous frame are reused to cull back-face polygons. | 03-29-2012 |
20120081368 | Image rendering apparatus and method - An image rendering apparatus may include a buffer memory unit and a processor. The buffer memory unit may store input ray data for image rendering according to a ray tracing scheme while shape data corresponding to the input ray data is being fetched from a cache. The processor may output the received shape data together with the input ray data to an operation apparatus. | 04-05-2012 |
20120081370 | METHOD AND APPARATUS FOR PROCESSING VERTEX - A method and apparatus for processing a vertex may fetch pieces of position information of vertexes, may extract pieces of target position information from the fetched pieces of position information, may perform tile binning on the pieces of target position information, may fetch pieces of attribute information having same indexes as the pieces of target position information, and may shade the fetched pieces of attribute information. | 04-05-2012 |
20140237403 | USER TERMINAL AND METHOD OF DISPLAYING IMAGE THEREOF - A user terminal and a method of displaying an image that includes displaying a plurality of display layers having different depths that are overlapped with each other, and in response to a user input being sensed, changing a depth of at least one of the plurality of display layers according to the user input, and providing a visual effect in response to the user input. | 08-21-2014 |
20140285494 | DISPLAY APPARATUS AND METHOD OF OUTPUTTING TEXT THEREOF - A display apparatus and a text output method thereof are provided. The text output method of a display apparatus acquires character information, determines character correction information for character information according to at least one of a characteristic of the display apparatus and a characteristic of an input character, generates a contour line of the character based on the character information and the character correction information to perform rendering, and outputs the rendered character. | 09-25-2014 |
