Abstract
A print monitoring system is disclosed using combination of analog signal processing circuits and signal processors on the slave processing boards to avoid the need for analog-to-digital converters and dedicated frame buffers between the slave processor and the video capture device. Additionally, the division of labor between the slave processors and the master processor is configured such that the slave processors perform a larger portion of the data manipulation, data analysis for the captured images. The master processor can be simply used to collect the decoded data and/or data analysis results from the slave processors and to run the interface to the operator to communicate the data/results. Finally, a graphical user interface between the user and the master processor is used to facilitate the calibration of the system and specifically the images captured by each of the video cameras.
