OnePlus 9’s IMX789 sensor detailed in early video, unique dual camera system teased

The first promo video for the Sony IMX789 is already out. In case you missed it, this sensor has been custom designed for the OnePlus 9 phones and their Hasselblad cameras. It has dual native ISO, full-pixel omni-directonal autofocus, it can record 4K video at 120 fps and supports real time HDR video processing.

The sensor will also feature Sony’s Digital Overlap HDR (DOL-HDR). Unlike staggered HDR, DOL is able to capture several exposures simultaneously, which helps remove ghosting caused by moving objects.

The first thing that the video demonstrates is the freeform lens for the ultra wide-angle camera. It suffers from much less distortion – 1% vs. 10-20% for a typical aspheric lens.

The system is actually quite unique as it uses two cameras placed lengthwise along the phone with two prisms redirecting light 90°. The image processing system will stitch the image in real time to create the extra-wide panorama with a 140° field of view.

The IMX789 will have a 16:11 aspect ratio, making it equally adept at shooting 4:3 photos and 16:9 video. 12-bit RAW will be supported for photography and Hasselblad will share its technology for capturing true to life colors.

OnePlus is bringing some upgrades for the selfie camera as well. The new autofocus system can get a lock 5-10 times faster than a traditional camera, it only needs 1 millisecond. The minimum focus distance has been shortened to 15 cm (6 inches) and the fast reaction times of the AF system allow it to keep a focus lock even as you move your hand.
