Frame Sync Between Cameras


I am seeking to make a project that captures a still photo from 2 to 4 cameras at the same time in complete frame sync.

Is there a way to share clock among multiple cameras and capture at the same time using the same settings?

Thank you for any advice you can offer!

Yes, it’s kinda janky however and only works for the OV7725 camera (the OpenMV Cam H7).

You need to connect the FSYNC input on the camera to a master clock source that runs at 60/120 Hz. The PLL inside the camera will sync up to that for frame output.

The clock should be like 60 Hz for VGA and 120 Hz for QVGA or less.

Awesome, thanks!
