Re: IR strobe for piNoir in sync with raspivid

I'm on my way with coding. As a start I've adapted the PiCamera recipe and can now retrieve the presentation time stamps (PTS) from each video frame. The times are in uS, so the least significant digit will be several clock cycles. In the default 30fps the stamps increase by about 33314 with very li...

Re: IR strobe for piNoir in sync with raspivid

@6by9 Thank you for answering my post. I was hoping that the average of processing time accumulated before the end of frame flag would be a constant. But I now consider my expectations have been managed ;) I welcome your thoughts on an alternative where the time offset between strobe pulse and camer...

IR strobe for piNoir in sync with raspivid

Previously elsewhere on these forums: https://www.raspberrypi.org/forums/viewtopic.php?p=941630#p941630 ... I modified the lights with my own drive circuit to be strobe lights that run at the frame rate of the camera, so even fast-moving objects appear as crisp still frames instead of motion-blurred...

Thank you again billw for your comprehensive help. For me pikrellcam is doing a great job in daylight hours.
