Abstract
본 발명은 특정 물체의 형상 정보만을 따로 검출하여 특정 물체를 구성하는 픽셀들의 픽셀값을 재 배열한후 부호화를 수행함으로서 부호화 효율을 높일 수 있는 영상 부호화 장치에 관한 것으로, 입력되는 영상의 특정 물체 형상 정보의 크기를 검출하는 수단; 상기 특정 물체의 크기에 상당하는 사각 형태의 메모리 공간에 재배열하는 수단; 상기 특정 물체의 각 수평 라인과 메모리 공간의 각 수평 저장 영역을 일대일 대응시켜 특정 물체의 픽셀값을 메모리 공간에 재 배열하되 특정 물체의 각 수평 라인의 시작점이 메모리 공간의 각 수평 저장 영역에서는 수직적으로 일치되게 배열하고 재 배열뒤에 남은 특정 물체의 잔여 픽셀값은 가상 메모리의 잔여 공간에 순차적으로 재 배열하는 수단; 상기 사각 형태로 재배열된 형상 정보를 8×8 블럭단위로 이산 여현변환하는 수단; 상기 이산 여현 변환 수단의 출력을 양자화하되 재배열 수단에 의해 잔여 공간에 재배열된 블럭은 상대적으로 높은 가중치를 부여하여 양자화하는 수단을 구비하여 구성함을 특징으로 한다.The present invention relates to an image encoding apparatus capable of increasing encoding efficiency by separately encoding only shape information of a specific object, rearranging pixel values of pixels constituting the specific object, and performing encoding. Means for detecting the size of the information; Means for rearranging the memory space in a rectangular shape corresponding to the size of the specific object; The pixel values of the specific object are rearranged in the memory space by one-to-one correspondence between each horizontal line of the specific object and each horizontal storage area of the memory space, and the starting point of each horizontal line of the specific object is vertically determined in each horizontal storage area of the memory space. Means for sequentially aligning and rearranging the residual pixel values of the particular object remaining after the rearrangement in the remaining space of the virtual memory; Means for discrete cosine transforming the rearranged shape information in 8 × 8 block units; The output of the discrete cosine transform means is quantized, and the rearranged blocks in the remaining space by the rearrangement means are provided with means for quantizing by giving a relatively high weight.
