An imaging module is described that acquires images of objects and outputs a digital image of the objects that is corrected for aberrations and flaws due to design, manufacturing constraints and variability, and, the local environment (temperature and humidity). The imaging module includes memory to store adjustment parameters, environmental sensors, and, a computing device that processes the raw acquired image into a corrected processed image. The imaging module is used with a test apparatus to calibrate the imaging module and calculate empirically determined correction factors that are stored in memory within the imaging module.
