ASI120MM camera and binning?
Posted 09 April 2013 - 06:18 AM
Where is the problem? Sam writes on his page camera can do 2x2 bin so it is problem with Fire Capture?
Thank you in advance for any idea.

It's not supported because FC uses a WDM library to drive the ASI and it's not available there.
I'll add binning to the next FC version. I would prefer using a native ASI SDK if Sam has fun implementing this If not I'll use simple software binning then.

And what about other programmes? Is 2x2bin working with any other capturing software?

So, maybe Sam hasn't enabled that feature yet through his driver, but the camera seems to support it.

Bird is right. MT9M034 support hardware binning.but CMOS's bin technical is different from CCD's which give twice sensetivity. that's why I used software bin in the driver.
@Torsten I really want to provide one Native ASI SDK. so FC can support it better.let's talk in email

I believe in an email you mentioned it is just a nearest neighbor technique, which would be even more useless as normal software binning.
To be honest, I don't really see an advantage of using software binning at all. Increasing the signal/noise ratio can be achieved using other more flexible methods.
(some background information on binning: http://www.andor.com...es-binning-mean . Summary: hardware binning is basically making one large pixel out of several smaller ones, with the same read noise as the smaller one. If you have a 5.6um camera at 640x480 with 10e read noise, and it supports 2x2 hardware binning, you now basically have a 320x240 11.2um with 10e read noise camera. In software binning you would have a 320x240 11.2um 20e read noise camera, not 40e as the read noise is added in quadrature)
