Device and method for decompressing compressed video image |
摘要 |
A method and device for decompressing a compressed video image and capable of enlarging or contracting the image at the same time. The method utilizes an enhancement/contraction pre-processor to perform enlargement or contraction processing on the compressed data in the vertical direction. Then, at a later stage, an enhancement/contraction post-processor is used to perform enlargement or contraction processing on the decompressed data in the horizontal direction. By dividing the whole video image into a number of rows and dealing with each row sequentially, memory for storing a single row of video data is only required. Therefore, a whole image can be decompressed without using large amount of memory for storing the decompressed data; a large amount of memory is saved.
