Point Grey GS3-U3-15S5M-C 2/3" Grasshopper-8 bit only?

Post by Maxtrixbass » Sun Jun 30, 2019 3:06 am

I am able to get Sharpcap 3.2 to run my Point Grey grasshopper camera only in mono 8. The camera specs say its a 14 bit mono camera.If I pick raw 16 or mono 16 the display is a pure mess of pure black and white, no grey at all. If I pick 12 bit it freezes.

Is there something I am missing? Do all 14 bit cameras capture in 8 bit?? Is it a display problem, that is it is capturing 16 bit but my monitor won't display it correctly?

Many thanks.

Hi,

Thanks for reporting this issue – I was unaware of it but I can certainly seem to reproduce at least part of it with the blackfly camera that I have to test with. The 12 bit mode also hangs for me. For me the 16 bit mode does give correct greyscales, but I find I often have two close down SharpCap and restart it to get the 16 bit mode to work. I'm sure used to work better than this – but it is quite a long time since I have done any work on the PGR cameras.

Cheers, Robin

Hi,

I found some problems with the 12 bit mode not being handled correctly so I have removed 12 bit modes in the latest version - in theory the 16 bit mode should give the same results. I also made some other changes to the code that supports PGR cameras.

Please have another go with the very latest version in 16 bit and see if it is improved. If not, please send a screenshot and a single frame capture (FITS format) so I can investigate further.

thanks,

Robin
