Abstract
An effects processor for an effects module. The effects processor comprises a RISC processor, a DSP for fast integer multiplication and a small memory. The processor uses VARK language and a lookup table of VARK scripts to apply a variety of effects to images stored outside the effects module. The effects processor includes a serial bus interface which communicates with the Serial Bus of a compact printer system comprising one or more further modules. The Serial Bus communicates power and data between the effects module and one or more of the further modules. Methods of compositing, convolving, warping and color substitution are described.
Claims8
A compact printer system having an effects processor for an effects module that applies effects to stored images, said effects processor comprising:
- a central processing unit;
- a fast integer multiplication unit;
- program memory comprises VARK language software associated with said central processing unit, said program memory storing program steps for execution by said central processing unit to apply effects to said stored images;
- an interface unit communicating with components of said effects module;
- and
- a serial bus interface for reception of stored images and transmission of resultant images.
