IMX582

IMX582 (previously LCM48) is a 48MP (8000x6000) rolling shutter color image sensor. It’s the highest resolution sensor that depthai currently supports. It’s integrated into the OAK-1 MAX.

Same as THE_5312X6000

Currently the full resolution (THE_48_MP) is center cropped to 5312x6000 due to ISP width limit. So at the moment the image at full resolution (THE_48_MP) has narrower HFOV than the camera actually is (see image below), just because of this limitation on line width.

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 ColorCamera node 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:

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

FFC compatibility

With OAK FFC boards you can easily evaluate different sensors and optics, as you can connect FFC camera boards to any OAK FFC baseboard (OAK-FFC-4P, OAK-FFC-3P) via a flexible cable. FFC camera boards are carrier boards for the CCM (additional information below), so it can easily be connected to any OAK FFC baseboard. The following FFC camera boards contain this sensor:

AF, NFOV

Sensor CCMs

Compact camera modules (CCMs) can be integrated directly into a custom product. CCMs are used in the final camera product. CCMs vary in optics and FPC connector. The following CCMs have been built using this sensor:

  • Arducam short FPC:

    • NFOV - 82° DFOV, 68° HFOV, 55° VFOV, EFL: 4.74, F. NO: 1.79±5%, Distortion: < 1.5%, Lens Size: 1/2”

      • AF: PY080

      • AF NoIR: PY101

      • AF IR notch filter (IR650+940): PY102

      • FF: PY106 (Focus: 50cm+)

    • WFOV FF (PY080) - 120° DFOV, 96° HFOV, 89° VFOV, EFL: 2.75, F. NO: 2.8±5%, Distortion: < -14.6%, Lens Size: 1/2”, Focus: 50cm+

Image quality comparison

Here’s an image comparison between different image sensors captured from OAK-FFC-3P. For more information, see Improving Image Quality docs.

Click on the image for the unencoded full-resolution sensor comparison image. Note that these images are about 8x digitally zoomed, and you can find full-resolution uncropped frames here (300 MB). Image specifications: Grocery items are at 4m, 33LUX, sensitivity 100ISO. Images were taken at 200ms,300ms,400ms,500ms exposure and combined with an HDR script (on the host). OAK Series 3 cameras will have native HDR support on the camera itself.
