Abstract

The present invention provides a plurality of interchangeable modules each of which is adapted to interface with at least one image receptor having predetermined physical interface parameters, including means for receiving image data from the at least one image receptor, processing means for converting the received image data into a converted, common format, and bus means for adapting to and communicating with a mother board. The interchangeable modules can be embodied in a plurality of daughter boards that are adapted for electrical connection to a mother board. Each daughter board can include the physical interface corresponding with the image receptor for which it has been programmed to receive data, with the physical interface being adapted for extending outwardly from a cabinet enclosing the daughter board and the mother board.
