question on SDK function - ASIStartExposure

[deleted]

Hi,

I'm a new visitor to this site.

I'm a software engineer writing some custom software for my ASI120MM camera running on my Raspberry Pi. I'm using the ASICamera2.h interface. Everything is working nicely and I'm able to take some nice timelapse images.

My question is: what is the second parameter to ASIStartExposure() used for?

The documentation in the header file is rather cryptic:

ASIStartExposure(int iCameraID, ASI_BOOL bIsDark)

// bIsDark: means dark frame if there is mechanical shutter on the camera. otherwise useless

I assume this has something to do with dark frame subtraction. But how do I use it?

Is dark subtraction done within the library (software) or within the camera itself (hardware) ?

Thanks for any info.

Hi Derek

this is a future feature

currently it's useless because we don't have camera build in mechanical shutter
