ISOCELL HM3 from Samsung conveys pro-grade photo capabilities to smartphones. It is designed for excellent color reproduction and low-light performance—the advanced pixel technologies aid you in capturing significant life moments.
All 108 million pixels combine to create superior quality pictures with refined detail. The 0.8 μm sized pixels are optimized to improve the clarity of images. The optical format of 1/1.33″ is analogous to a massive canvas regarding image sensor size. So, this sensor can absorb more light to assist you in capturing clear photos whenever you press the shutter button.
- With the Smart-ISO Pro, this sensor is built to capture various brightness levels within the frame accurately. It blends two images in which one highlights vivid areas, and another conveys details in dark regions.
- With the low-noise mode, this sensor helps you to capture clear and bright images with less noise in a dim light environment.
- Each shot expresses more colors because this sensor supports 12-bit color depth that elevates color reproduction in mobile photography to the next level.
- More than 68 billion colors are expressed, suggesting that image output shows 64 times more colors than the 10-bit color depth.
- This sensor virtually transforms pixel patterns based on the amount of available light. In bright light conditions, this sensor maximizes details through its enhanced remosaic algorithm, leading to brilliant 108MP photos.
- During low-lit environments, nine pixels absorb more light and produce vivid 12MP images.
- With the use of the AF-optimized micro-lenses, the Super-PD Plus increases the AF speed in low-light settings. This is done while simultaneously boosting its accuracy. The fast autofocus equips you with the ability to capture blur-free photos of any fast-moving object.
- This sensor transforms everyday scenes into amazing videos through 8K and 4K video recording support.
- 8K video recordings @ 30fps are optimized to improve and convey all details in the frame.
- While recording in 4K, this sensor records at a speed of 120fps. Hence, you can create slow-motion videos.

- The nine-pixel binning technology lets the sensor combine nine tiny 0.7μm pixels into a big 2.1μm pixel to absorb more light. So, this technology guarantees outstanding low-light performance and enables the sensor to generate excellent output in all lighting conditions.
- This sensor can capture bright, clear 12MP photos in low light conditions. On the other hand, the sensor makes the most of the full 108MP resolution to capture highly detailed photographs. Hence, the best results are guaranteed in any light environment.
- The high-dynamic range captures stunning images and video, although there is mixed-lighting condition.
- Three images captured at varying exposure levels are combined to generate HDR images in real-time.
- The output images are realistic through unique highlights, contrast, and shadows.
- This sensor finds the optimal ISO setting through Smart-ISO technology. So, noise is reduced, and picture quality is optimized.
- The high ISO is automatically selected to obtain clearer, brighter images in a dim light environment. No extra noise was added.
- The sensor shoots in low ISO in a bright light environment to present color-accurate images with high fidelity.
- With the Gyro Electronic Image Stabilization (EIS), this sensor ensures steadiness in your footage while you shoot a fast-moving scene on the go.
- The ability to shoot in 8K @ 24fps makes sure all videos you shoot will show cinematic, ultra-high-resolution detail.

- 64 MP effective pixel resolution is dependent on the image sensor effective pixel specification technique.
- The Quad Bayer color filter array helps the sensor to create a 16 MP high-resolution binned image with a pixel size of 1.6μm.
- Quad Bayer array provides high sensitivity and high resolution.
- The Quad Bayer color filter merges 2×2 adjacent pixels to generate a single large pixel. Therefore, pictures with 12 MP and 16 MP resolution are created.
- The 4-in-1 pixel-binning process increases the original edge length of every pixel. This increment is from 0.8 µm to 1.6 µm. So, it facilitates improved light absorption that shows all details in an image.
- 2×2 On-Chip Lens (OCL) solution utilizes a condenser lens at the uppermost part of four neighboring pixels that are organized in a Quad Bayer color filter array. This arrangement improves phase detection and ensures high accuracy for small objects. Moreover, it raises the focus performance in dim light environments.
- The cutting-edge sensor technology enables the sensor to improve low-light capturing ability by improving the light utilization factor.
