Touptek driver problem

[T-Studio]

Thank you for providing such great software.

I'm using the latest SharpCap 4.1,
There is a problem with the Touptek camera driver.

Format→Mode

1. Color balance cannot be adjusted in Raw8 and Raw16.

2.The binning function is not working with RGB24.

I would like to use the binning function in RGB24 mode.

The camera is
It will be IUC26000KPA.

Hi,

I'm sorry to say that this is pretty much how it is supposed to work for the RAW modes...

In RAW modes, there is no colour balance adjustment allowed by the ToupTek SDK. The point of these modes is to read and save the exact image data created by the camera sensor. If you want to adjust colour balance it's far better to save the unadjusted data then adjust in post processing.

I'm surprised by the binning problem - all the ToupTek cameras I have seem to allow me to use binning in RGB24 mode and it seems to work correctly (you get an image which looks the same as the unbinned image, but has smaller pixel dimensions). Note that the binning function *does not* make the image brighter for these cameras (if you want that, turn up the gain or exposure) - it averages the binned pixels together, so it reduces noise in the image.

cheers,

Mr.Robin

thank you for your reply.

In RGB24 mode binning, the camera's processor generates a color image and bins it, resulting in a change in brightness.

If you use ToupViewToupSky distributed by Touptek, the brightness of the image will change significantly.
Binning adds ratings instead of averaging them.

Both modes seem to be available in ToupView and ToupSky, but what's useful with EAA is the addition.

SharpCap has also changed in previous versions. (However, there was a bug that made it impossible to use anything other than 2 binning)

This mode is useful because it can brighten images by adding and combining pixels with EAA, so I would like to be able to use it like ToupView and ToupSky.

I purchased this camera with a plan for how I would use this blog post.

I also own a ZWO camera and use the RGB24 binning mode to shorten exposure times.

Hi,

there's actually no difference in terms of image Signal/Noise ratio between additive binning and averaging binning, so either will do the job quite nicely. If your camera uses averaging binning and you really wanted the image to get brighter, you can achieve an essentially identical output to 'additive' binning by using the averaging binning and turning up the gain to brighen the image by the required amount. This is covered in more detail in the SharpCap user manual - https://docs.sharpcap.co.uk/4.1/#Binning

Hope this helps,

Robin

thank you for your reply.

When using the genuine ToupSky, it supports both averaging and additive binning with binning in RGB24 mode.

Previous versions of SharpCap and the Linux INDI driver only support Additive binning mode.

In my operating method described in my blog, I want to increase the gain to the maximum and use binning to make it even brighter, so averaging is not useful. . .
Additive binning is common for RGB24 mode, so we would appreciate it if you could support it. (Many people use binning to obtain brightness rather than to reduce noise.)

The result will be the same even if you increase the upper limit of the gain with a multiplier that corresponds to the binning process, so it is a good idea to specify that the upper limit of the gain also increases according to the binning process. . . . However, this is not a common use of binning.
