[fprint] Fingerprint not recognized

[Иванов Михаил]

Greetings! I tried libfprint under debian unstable. When I run verify_live
my fingerprint is always reported as invalid. I try to capture the fingerprint
with img_capture and I see that the quality of the fingerprint is very poor,
namely it is very dark. Is there a way to adjust image brightness?

I have hp nw9440 laptop with AuthenTec AES2501 sensor. I have applied
aes2501 fix from mailing list.

Best regards!
