Smart synchronization method of a web inspection system

A smart synchronizing method of a web inspection system for monitoring a moving web and comprising a master camera configured to act as a synchronizing device and at least one slave camera, and at least one lighting device arranged to illuminate an area of the web arranged to be imaged, the method comprising:

• transmitting a synchronizing signal to the at least one slave camera by the synchronizing device, wherein the synchronizing signal comprises at least a start pulse and serial data comprising additional information for the at least one slave camera, which additional information is configured to be used for combining of images of adjacent cameras, and wherein all the cameras of the web inspection system are configured to be synchronized with each other based on the start pulse indicating a synchronization moment when integration of the cameras ends,
• transmitting a light synchronizing signal to the at least one lighting device by the synchronizing device, wherein a light controlling pulse of the light synchronizing signal indicates switching on and off times of the at least one lighting device, which switching off time corresponds to the synchronization moment, and
• calculating a starting time of integration based on an individual integration time of a camera and the synchronization moment common for the cameras of the web inspection system.
