Chronos User Discussion / Mixed images in segmented mode
« on: January 26, 2022, 09:04:34 AM »
Hi,
We use a Chronos 1.4 (0.6 firmware) to shoot typically 50 blocks (segments) of 400 images at close to max frame rate (995fps). FWIW each segment is started at about 5 seconds interval, using an external TTL trigger on the BNC input of trigg1.
I would expect the exported images to be frame_000001.tiff->frame_000400.tiff for the first block, then 401->800 for the second block and so on. But instead the first block only has 398 images (frame_000001.tiff->frame_000398.tiff) while the second and the others (except the last) have the expected 400 images (399->798, 799...). Finally, the last block contains 403 images, the last 3 of which seem to belong to the beginning of the first block.
Is this a known issue and if so is there a workaround?
Since my explanation may be confusing, don't hesitate to ask for details.

Chronos User Discussion / Re: Can the pictures taken by the Chronos 2.1 camera be named automatically by time?

This is an interesting feature, but will the name refer to the time the image was shot or to the time it was written to disk?

Chronos User Discussion / Image patchwork issue
« on: January 26, 2022, 08:46:35 AM »
Hi,
We are using a Chronos 1.4 camera (version 0.6 of the firmware) for scientific purpose (mainly particle tracking) and we are observing a very annoying issue: some images are corrupted and look like a patchwork of other images. I attached an example image which we found in the middle of a 20000 images video exported as a collection of 8bit tiff files.
This happens once in a while and we have not been able to devise precise conditions in which this happens. Is this a known issue? If so, is there a workaround?
