Abstract:
A system for monitoring a process, said system comprisinga number of cameras (1) for imaging various positions in a presently monitored process; digital image processors (2) for storing digital image information as per camera and for analyzing each camera-specific image information so as to provide image variation data based on the level of variation in several sequential images; and a display or screen (11) which can be used for selecting images (10) stored from various camera positions for analysis, while using the screen (11) for displaying an image variation graph (8) representing the image variation data of images preceding and following the image (10) to be analyzed, characterized in that the system comprises standardizing devices (3) for standardizing the output levels of the image variation data from various camera positions to be mutually comparable; comparator elements (4) for a mutual comparison between said standardized image variation data from various camera positions; and selector elements for selecting the camera position with the highest-level image variation for automated display; said selector elements (5) being in communication with the digital image processors (2) for receiving image data from various camera positions, and said comparator elements (4) being adapted to control the selector elements (5) in such a way that the image data representing the highest-level variation and the image variation graph (8) consistent therewith are selected for an automated display on the screen (11).
