RVC2 supported resolutions

Resolution name	Resolution size	Max FPS	MIPI lanes	Mode
`THE_48_MP`	5312x6000	10	4	Full resolution and maps to THE_5312X6000 (not supported)
`THE_5312X6000`	5312x6000	10	4	Width is cropped - QBC remosaic’ed mode
`THE_4000X3000`	4000x3000	30	4	Full FOV - QBC Binning
`THE_4_K`	3840x2160	42	4	QBC Binning (to 4000x3000) then Cropping

RVC4 supported resolutions

Resolution name	Resolution size	Max FPS	MIPI lanes	Mode

`/`	4000x3000	30	4	Binning 2x2

RVC2 driver limits

Sensor driver adds support for that sensor to the RVC2. Here are RVC2 driver specifications for this sensorPart of the ISP (Image Signal Processor) is also the 3A (Auto Exposure, Auto White Balance, Auto Focus) algorithm. They are enabled by default, but you can also disable them and manually set the exposure, gain, white balance, etc.

Manual limits

Min FPS: 1.67
Min exposure time: 1 μs
Max exposure time: 1 / CAM_FPS seconds. Eg. 33ms @ 30FPS

Auto limits

Min exposure time: 101 μs
Max exposure time: Depends on the Anti-Banding mode:
- Anti-Banding mode OFF: 33 ms
- Anti-Banding mode 50Hz: 30 ms
- Anti-Banding mode 60Hz: 25 ms

Max AE exposure time depends on the Anti-Banding (AB) mode, which helps to avoid flickering when using artificial lighting. We can configure the AB using the API:

Python

1cam = pipeline.create(dai.node.ColorCamera) # Or MonoCamera
2# "OFF", "MAINS_50_HZ", or "MAINS_60_HZ"
3cam.initialControl.setAntiBandingMode(dai.CameraControl.AntiBandingMode.OFF)

IMX582 RAM consumption

At highest resolution, the IMX582 image sensor produces 32MP frames, which can consume a lot of RAM. As OAK cameras are embedded devices, they don’t have a lot of RAM to begin with. In most pipelines, even just the color camera with default pool sizes will be too large, so you need to be very cautious when it comes to RAM and we suggest reading the RAM usage documentation . For ColorCamera node, you’d likely need to change pool sizes, example here:

Python

1cam = pipeline.create(dai.node.ColorCamera)
2cam.setResolution(dai.ColorCameraProperties.SensorResolution.THE_5312X6000) # 32MP
3# Decrease pool sizes for all outputs (raw, isp, preview, video, still):
4cam.setNumFramesPool(2,2,1,1,1)

High Dynamic Range (HDR)

IMX582 sensor supports on-sensor HDR, so it can be leveraged by the Robotics Vision Core 2 (RVC2) as well. In the comparison image below we are using OAK-1 Max.HDR image comparison in different exposure settings:

For the HDR image above we used the following argument for cam_test.py:

Command Line

1python3 cam_test.py -cams rgb,c -rs -cres 12mp -fps 10 -misc hdr-exposure-ratio=4 hdr-local-tone-weight=75
