For capturing and analysing of fast moving objects (e.g. as in quality control of production lines) modern high speed cameras are frequently used.
By using a so-called "image trigger" this task can be done much faster and more accurately, without the cost and effort of additional equipment as in standard methods (for instance, via cable release).
The on-board "ImageBLITZ" image trigger uses the live picture of the camera itself as a flexible and accurate sensor, with the result that the process synchronisation takes care of itself.
[1] By using CMOS cameras (which provide the information of every single pixel in digitized form) a fast processing of the supplied data is ensured.
To prepare the ImageBLITZ, a line segment of a predefined length is set up in the field of view, just where the triggering event is likely to take place.
