Hi,
We are developing a platform that uses Jetson TX2 along with IMX477 CSI image sensor for a lens-less holography project. We are using libargus api to receive frames from the image sensor.
However, as of now, each individual frame has different intensity. Values of individual pixels have deviation of up to 10 percent from the average value. That should not be the case since the lighting conditions are constant on our platform and we turned off automatic ISP gain. We also locked auto white balance and auto exposure.
The current settings look like this
ISourceSettings *iSourceSettings = interface_cast<ISourceSettings>(iRequest->getSourceSettings());
iSourceSettings->setFrameDurationRange(Range<uint64_t>(1e9/DEFAULT_FPS));
iSourceSettings->setExposureTimeRange(Range<uint64_t>(Settings::values[STG_EXPOSURE],Settings::values[STG_EXPOSURE]));
iSourceSettings->setGainRange(Range<float>(1.0,1.0));
IAutoControlSettings *iAutoSettings = interface_cast<IAutoControlSettings>(iRequest->getAutoControlSettings());
iAutoSettings->setExposureCompensation(0);
iAutoSettings->setIspDigitalGainRange(Range<float>(0,0));
iAutoSettings->setWbGains(0);
iAutoSettings->setColorSaturation(1.0);
iAutoSettings->setColorSaturationBias(1.0);
iAutoSettings->setColorSaturationEnable(true);
iAutoSettings->setAwbLock(true);
iAutoSettings->setAeLock(true);
Is there anything we have missed or set wrong?
Thank you all in advance
