Abstract:
1. An image processing method, comprising: scanning an original document to generate image data corresponding to the scanned original document; dividing the image data of the scanned original document into a plurality of image data blocks; compressing the plurality of image data blocks into respective compressed image data blocks, such that data of each compressed image data block is independent of data of each other compressed image data block; storing each compressed image data block in a first memory with a respective predetermined beginning address; accessing a first compressed image data block, having a first predetermined beginning address, from the first memory and decompressing the first compressed image data block into a first decompressed image data block; and performing at least one image processing function on the decompressed first image data block; and storing the decompressed first image data block in a second memory after performing the at least one image processing function, wherein one of the at least one image processing functions is to rotate the image data, wherein a second compressed image data block is stored in the first memory and has a second predetermined beginning address that is offset by a predetermined amount from the first predetermined address, the method further comprising: accessing the second compressed image data block from the first memory and decompressing the second compressed image data block into a second decompressed image data block; performing the at least one image processing functions on the second decompressed image data block; and storing the decompressed second image data block in the second memory after performing the at least one image processing function.
