Optical Sensor

[Bala Subramaniyan]

Dear all,

I'm trying to capture the video frames from the optical fingerprint sensor using v4l4j files. But i'm getting a black screen display only. The output of the fingerprint scanner will be a gray scale image of size 240 X 320 with a resolution of 500 dpi.  How can i get a clear fingprint image?

Thanks for your reply in advance.
