First thing was that the proportions seemed to be wrong. So I inked my finger, got a print on paper, scanned it and compared it with the image from the FPS. That seemed to be too short (ore too wide). Additionally I had the impression, as if every now and then in the image a line was missing. Then I remembered some stuff I learned in earlier days about television. I googled for some more information and everything fits. In NTSC a picture is 384 pixel high and 576 pixel wide. The picture is transmitted in two halfs with one picture ending in the middle of the line and starting in the middle of the next first line. Digital Persona is using a simple chip from a video-camera and the camera in the FPS is turned by 90 degrees. Good and extremely cheap solution! There aught to be another half picture in the transmitted data and this one should end with half a line. Additionally I saw pictures from the same sensor using other SDK´s with the proportions looking right. Best regards. I did some tests with the program.

But, How to use it next? I'm using gnome and gdm for example...how to log into gnome with my fingerprint? Thanks a lot for your job, Best regards.

You are free to contribute code to convert that into whatever format you desire.
