Change iso value?

I can manualy set exposure value, but I would also like to gain the image like a higher iso value would do so that I can keep good fps with sharp image.

When using autoexposure the camera keep good fps even in a dark room by . How do I do the same manualy with constant exposure value?

I have tried using ColorGain without luck. The change is where small and I don't get that noise that I get when using autoexposure in low light.

An example. When using autoexposure I can hold my hand very very close to tha camera and I get a bright of my hand with good framerate. If I set exposure manualy like -2 that would give me a image that is as bright as with autoexposure but I get very low framerate.

Hi Ankan,

 

 

Thank you for getting in contact. Let me try to help you with your question.

 

I was looking for other thread regarding changing/setting the ISO value for the cameras and found one from April, you might want to take a look at it /thread/113611 https://communities.intel.com/thread/113611. Let us know if you find that information helpful.

Hi, Pablo,

I have already read that thread but it didn't help me much. Instead I tried to change multiple properties and got it working good enough.

I used setColorGain to start with but I also had to change setColorExposure, setColorGamma and setColorSharpness to get a brighter image without changing exposure.
