Abstract
This invention provides a system and method for enabling control of an illuminator having predetermined operating parameters by a vision system processor/core based upon stored information regarding parameters that are integrated with the illuminator. The parameters are retrieved by the processor, and are used to control the operation of the illuminator and/or the camera during image acquisition. In an embodiment, the stored parameters are a discrete numerical or other value that corresponds to the illuminator type. The discrete value maps to a corresponding value in look-up table/database associated with the camera that contains parameter sets associated with each of a plurality of values in the database. The data associated with the discrete value in the camera contains the necessary parameters or settings for that illuminator type. In other embodiments, some or all of the actual parameter information can be stored with the illuminator and retrieved by the camera processor.
