Abstract:
PURPOSE: A deblocking filter calculation device and a method thereof including a common data pass structure are provided to integrate a data pass which performs strong intensity filtering and a data pass performing average intensity filtering. CONSTITUTION: A critical value generating unit generates a critical value from an inputted index value. An edge judging unit determines whether an edge, which is a current filtering target, is made due to an error because of a blocking artifact or not by using an input pixel data which will be filtered with the generated critical value. A filtering calculation performing unit selectively performs an average intensity filtering calculation or a strong strength filtering calculation according to an inputted boundary intensity coefficient. An outputting unit outputs an average intensity filtering calculation result or a strong intensity filtering calculation result.

PURPOSE: A deblocking filtering method is provided to perform a deblocking filtering operation in a spiral rotating order fro an image comprising plural macro blocks. CONSTITUTION: For the first and second macroblocks placed in the central portion of an image, a deblocking filtering operation is performed. One side of the first macro block contacts the one side of the second macro block. According to the spiral-rotating order in relation to the center of the first macro block, the deblocking filtering operation is performed for the boundary of the macro blocks which are adjacent to each other. For the vertical and horizontal direction boundaries in the macro block, the deblocking filtering operation is performed one time.

본 발명, 시선 인식을 이용한 풀 브라우징 방법 및 이를 적용한 휴대용 단말기는, 적외선 카메라를 통해 입력되는 신호를 통해, 사용자의 시선을 인식 및 추적하고, 상기 인식 및 추적된 사용자의 시선이 디스플레이부의 가상 경계범위를 벗어나는지 판단하며, 사용자의 시선이 디스플레이부의 가상 경계범위를 벗어나는 경우, 디스플레이부 상에 디스플레이 중인 이미지의 중심을 이동하여 디스플레이 함으로써, 화면의 터치나 버튼의 조작없이 시선의 이동만으로 기존의 화면터치방식보다 더 편리하게 신속하게, 작은 화면에서 원하는 정보를 찾고 조작 가능하도록 하여, 휴대용 단말 사용자의 편의성을 증대시킨다. 시선 인식, 풀 브라우징, 적외선 카메라, 휴대용 단말기, 좌표
Abstract:
PURPOSE: An apparatus and a method for recording accident information for a vehicle are provided to transmit driver information of a rear-ending assaulting car, thereby obtaining information of the car. CONSTITUTION: A wireless communication unit(74) performs wireless communication with a car or a main car accident management server. A collision detection sensor unit(75) detects generation of collision. A controller(71) exchanges car information and accident related information with a counterpart car which collides with the car. The controller requests the information of the counterpart car to the main accident management server.
Abstract:
PURPOSE: A method for determining boundary strength in a deblocking filter is provided to simplify some parts of a boundary strength generation process by an encoding/decoding condition. CONSTITUTION: An integrated comparison unit(240) compares the identity of a reference image and motion vector in X, Y directions among neighboring blocks. A logical unit(210) determines boundary strength by discriminating the coding type of a macro block. A second logic unit(220) determines boundary face intensity by using an encoding residual coefficient. A third logic unit(230) determines the boundary face intensity through the operation result of the integration comparison unit. According to the intra prediction coding of a processing macro block, a clock gating unit(250) controls the integration comparison unit and the operation of the third logic unit and the second logic unit.

PURPOSE: A de-blocking filter apparatus of a pipeline structure using a vertical filter and a horizontal filter reusing the data is provided to reduce the entire buffer occupancy by removing the use of pre-buffer. CONSTITUTION: A buffer memory(210) stores the row direction data of a macro block. A B buffer memory(220) stores the column direction data of the macro block. A horizontal filter(260) performs horizontal filtering operation about a vertical edge by one or more pipe stages by the row direction data. A vertical filter(270) performs vertical filtering about the horizontal edge.
