20120159428 | METHOD OF DETERMINING MULTIMEDIA ARCHITECTURAL PATTERN, AND APPARATUS AND METHOD FOR TRANSFORMING SINGLE-CORE BASED ARCHITECTURE TO MULTI-CORE BASED ARCHITECTURE - A method and apparatus for authoring an architecture for transforming a single-core based embedded software application to a multi-core based embedded software application, and a method of determining an architectural pattern in a multimedia system. It is possible to perform an architecture authoring operation by using an architectural decision supporter, without prior knowledge and accumulated knowledge regarding a software architecture. Additionally, it is possible to prevent an error from occurring during authoring of an architecture, by using a concurrency-related software architectural pattern that is already evaluated. Thus, it is possible to improve overall quality of software, and to reduce a development time. | 06-21-2012 |
20120328193 | METHOD FOR ENHANCING IMAGE EDGE - Disclosed is a method for enhancing an image edge. An edge filter is applied to a photographed image, and the determination is performed with respect to whether pixels having edge possibility are noise or form an edge. The determination for the noise and the edge is performed once more with respect to pixels having vagueness for the noise and the edge by using a 3×3 mask. An edge enhancement process is performed through a simple algorithm. | 12-27-2012 |

20130002941 | METHOD OF CONTROLLING ADAPTIVE AUTO EXPOSURE BASED ON ADAPTIVE REGION WEIGHT - Provided is a method of controlling adaptive auto exposure. In the method, a digital photograph captured from an object and a background is divided into an object region where the object is mainly located and a background region where the background is mainly located. Average luminances of the object and background regions are calculated, and a luminance difference between the average luminances of the object and background regions is calculated. If the luminance difference is within a predetermined range, an average luminance of the entire photograph is calculated by applying a weight to the average luminance of the object region, and exposure is controlled based on the calculated average luminance of the entire photograph so as to emphasize the object region. | 01-03-2013 |
