Argus Auto-Exposure Region of Interest not working

Our custom application argus code for auto exposure region of interest worked on previous releases on TX2 4GB. Running it on L4T 32.2 and Argus Version: 0.97.3 seems to ignore the region of interest and expose for the whole frame.

I’ve replicated the issue in the eglImage Argus sample with this diff:

diff --git a/main.cpp b/main.cpp
--- a/main.cpp
+++ b/main.cpp

+    IAutoControlSettings *iAutoControlSettings = interface_cast<IAutoControlSettings>(iRequest->getAutoControlSettings());
+    if (!iAutoControlSettings)
+        printf("Failed to get IAutoControlSettings interface\n");

+    regions.push_back(testRegion);
+    Argus::Status result = iAutoControlSettings->setAeRegions(regions);
+    printf("iAutoControlSettings->setAeRegions result = %d\n", result);
     // Start the EGLImage rendering thread.
     EGLImageRenderingThread renderingThread(outputStream.get(), options);

When the sensor is running with a well-lit scene, physically covering one corner with black should ramp up the exposure a lot, resulting in blown out whites. This does not happen.

Can anyone else confirm this? Is this a bug in Argus 0.97.3?

hello davidkh1m9,

it’s a duplicate issue, please keep this in the original discussion thread, Topic 1064309.
