1. A system for processing image data in a digital image device, said system comprising:

  • a bus;

    a central processing unit coupled to said bus;

    an image processing subsystem coupled to said central processing unit for processing said image data using a particular processing mode;

    a memory unit coupled to said bus, said memory unit having stored therein an operating system comprising instructions executed by said central processing unit to manage said image processing subsystem;

    said memory unit further having a data structure corresponding to said processing mode, said data structure comprising a plurality of buffers for managing said image data for said image processing subsystem during image processing, said data structure providing an interface between said operating system and said image processing subsystem, such that said operating system is independent of said processing mode used by said image processing subsystem; and

    a data storage element coupled to said bus for storing said image data after image processing.
