Our library supports setting camera IQ (Image Quality) tuning blob, which would be used for all cameras. By default, cameras will use a general tuning blob, which works great in most cases - so changing the camera tuning blob is not needed for most cases.
import depthai as dai pipeline = dai.Pipeline() pipeline.setCameraTuningBlobPath('/path/to/tuning.bin')
Available tuning blobs¶
To tune your own camera sensors, one would need Intel’s software, for which a license is needed - so the majority of people will only be able to use pre-tuned blobs.
Currently available tuning blobs:
Mono tuning for low-light environments here. This allows auto-exposure to go up to 200ms (otherwise limited with default tuning to 33ms). For 200ms auto-exposure, you also need to limit the FPS (
Color tuning for low-light environments here. Comparison below. This allows auto-exposure to go up to 100ms (otherwise limited with default tuning to 33ms). For 200ms auto-exposure, you also need to limit the FPS (
rgbCam.setFps(10)). Known limitation: flicker can be seen with auto-exposure over 33ms, it is caused by auto-focus working in continuous mode. A workaround is to change from CONTINUOUS_VIDEO (default) to AUTO (focusing only once at init, and on further focus trigger commands):
