ABSTRACT:
An improved error-diffusion image processing system and the method thereof adopt the block reading mechanism to replace the row reading mechanism employed in the conventional error-diffusion image processing. This can greatly reduce the memory space required for image processing and increase the operational efficiency. The problem of gaps existing in the block reading mechanism is solved by adding a required error sum (BEsum) in a summed pixel range according to specific position conditions of each block.
