How to turn off auto exposure from camera setting?

I'm trying to develop an application that is using the primary camera to take pictures. I hope I can control iso level and exposure but it doesn't seem CAMERA_PRIMARY_SUPPORT_EXPOSURE returns success with the line below.

r = MediaCapability::GetValue(CAMERA_PRIMARY_SUPPORT_EXPOSURE, Value);
 

I think it means my PQ device does't suport exposure. Then, could somebody please tell me what kind of options I have? I tried to use brightness but I couldn't see the difference that much for differnt brightness levels from camera inputs. What I want to do is adjusting exposure but I'm not so sure if I can get the different pictures with brightness adjustment.

I was wondering if it might be related to auto exposure mode so I tried to change auto exposure mode but it doesn't seem CAMERA_METERING_MODE_NONE is a valid input for MeteringMode.

Could somebody elaborate on Tizen camera exposure mode and level setting?

Thanks,

Hi Lee,

Yes looks like you dont have exposure feature in your device. you can try changing the brightness levels and contrast levels. Also make sure you have set the camera privilege and features as per the required feature in the manifest file. For more on camera options in Tizen API please go through this link.
