Hello everybody, me again with another question. I have my Quickcam up and running beautifully now, however, I've run into another problem today..
I'm trying to take every two successive frames with completely different lighting conditions. The lighting is controlled by a hardware setup connected to the parallel port. Now, I've noticed that the flash that should be visible only in the odd-numbered frames is most of the time also visible in the even-numbered frames. I have to add a delay of up to 30 ms before and after taking the image, only then the separation between the two different lighting conditions is acceptable. So, my question is: can the camera actually cause a variance of up to +- 30 ms? I'm using mmap IO with 2 buffers. I've tried up to 16, without a noticeable change. Any hints? Thanks, Yours, Florian
