LYYN Hawk Portable and the latest software revision of LYYN Hawk Board has a new feature: inverted lyynification window.
This new feature comes as a request from the inpipe inspection business, but can of course be usefull in many applications.
The reasoning behind the feature and how it works.
The whole idea behind the selection window is that there in certain situations might be very high contrast, color or visual disturbance differences across the image. You position the lyynification window where you want the enhancement, without having the rest of the image influencing the automatic optimization process.
Usually you enhance the center of the image even though you can position the enhancement window on the corners or sides of the image. When performing inpipe inspections you are usually more interested in the edges of the image than the center. The image has extremely high contrast with the center of the image being very distant and pitch dark while you inspect the walls of the pipe.
This example shows the difference (even though it has dark walls and very bright center):
How to control the Inverted Window:
In LYYN Hawk Portable this feature is only accessible through the serial interface (RS232 port for computer control). There are no manual controls, buttons or knobs for this feature.
In LYYN Hawk Board Integration Kit you can access this new feature either on the serial control interface or the touch control pad. By pressing and holding the “+” button while pressing the window button you toggle inverse on and off.
