Smart ISO Pro is an HDR technology that captures one high ISO and one low ISO shot simultaneously. As both are captured at the same time, this avoids the ghosting of moving objects that is a problem for sequential HDR.
Then the two shots are combined into a single 12-bit image. Thatโs 12-bits per channel, meaning the RAW image contains 64 times more color information than a 10-bit image.
The HM3 also features a Low Noise mode, which improves light sensitivity by up to 50%. Alternatively, in good lighting conditions an enhanced remosaic algorithm can output full resolution 108 MP images.
Super PD Plus adds micro-lenses to the Phase Detection elements used by the sensor for autofocus. The lenses improve the measurement accuracy of those elements by 50%, which allows the sensor to accurately track moving objects even in the dark.
For video, the ISOCELL HM3 can capture 8K footage at 30 fps, 4K at 120 fps and 1080p at 240 fps. Note that the S21 Ultra is limited to 24 fps at 8K resolution. On the plus side, you can use an S Pen when editing videos for more precise manipulations of the timeline with frame-level accuracy
The 1/1.33โ sensor lays out its pixels in a 12,000 x 9,000 grid. However, the Nonapixel Bayer pattern allows for 9-to-1 pixel binning, so the effective pixel size becomes 2.4 ยตm and the resolution 12 MP.
