Apparatuses and methods for processing a picture frame are provided. The apparatus comprises a decoder, a memory, and an image processing unit. The decoder decodes blocks of the picture frame and deblocks decoded blocks to generate deblocked blocks. The memory stores the decoded blocks and deblocked blocks. The image processing unit acquires decoded or deblocked blocks through different paths, for example, from the decoder or from both the decoder and memory depending on whether a next MB row is required for deblocking.
