ABSTRACT:
The invention describes systems and methods to obtain and present imaging data in absolute units. The systems and methods convert relative image data produced by a camera to absolute light intensity data using a compensation factor. The compensation factor accommodates for hardware and specific imaging conditions in the imaging system that variably affect camera output. The present invention determines the compensation factor based on assessing the output of the camera against a known light source for a specific set of imaging conditions in the imaging system. The compensation factor is then stored in memory corresponding to the specific set of imaging conditions. Upon subsequent imaging with the set of imaging conditions, the corresponding compensation factor is called from memory and applied to the camera output. A compensation factor may be determined and stored for each hardware state and imaging condition available to the imaging system.
