[fprint] How to increase delay for reading the fingerprint ?

[Kleyson de Sousa Rios]

Hi,


How do I increase the waiting time between placing the finger on the reader and the driver capture the image ?


I noticed that when I have more time with the finger on the reader before the image be capture, I get a fingerprint image with a higher quality.


To conclude that, I did the following experiment:


(1) Execute the examples/img_capture and then put the finger on the reader

(2) First put the finger on the reader and then execute the examples/img_capture program


The image captured from (2) has a higher quality than the image captured from (1).



Best Regards.

Kleyson Rios.
