Notably, the HP9 excels in low-light conditions, addressing a common challenge for traditional telephoto cameras. The ISOCELL HP9 is Samsung's groundbreaking mobile image sensor with some impressive features:
- High Resolution: It boasts an industry-leading 200MP resolution, featuring 200 million 0.56-micrometer (μm) pixels in a 1/1.4-inch optical format. This makes it one of the most high-resolution sensors available for mobile devices.
- In-Sensor Zoom: The HP9 supports in-sensor zoom using Tetra²pixel technology. It can zoom in up to 4x while maintaining crisp detail. When combined with a 3x telephoto module, it can achieve extreme zoom capabilities, going up to 12x with just the camera module.
- Pixel Binning: The sensor optimizes pixel array for different lighting conditions. As light dims, it automatically merges neighboring pixels into one, allowing them to operate as a single 1.2µm-sized pixel with 50MP or a 2.4µm-sized pixel with 12.5MP. Even after zooming in at 4x, it still operates at 12.5MP, utilizing more pixels than 12MP sensors before zooming. This results in clearer low-light pictures with less noise.
- High Precision Microlens: The HP9 uses a highly refractive material applied to the microlens, allowing it to more precisely collect and guide light toward the photodiode. This reduces crosstalk, increases the signal-to-noise ratio (SNR) by 38% compared to its predecessor, and improves autofocus performance by 10%.
- Smart-ISO Pro: It can express over 4 trillion color combinations thanks to its 14-bit color depth, which is 64 times greater than 12-bit sensors. This was achieved by applying higher conversion gain for High ISO and merging two readouts: one with High/Mid ISO and another with Low ISO. Additionally, it uses Staggered HDR to capture images with a wider dynamic range.
- Effective Resolution: 16,320 x 12,288 (200M)
- Pixel Size: 0.56μm
- Optical Format: 1/1.4"
- Color Filter: Tetra²pixel RGB Bayer Pattern
- Frame Rate: 7.5 fps @ full 200 MP, 27 fps @ 50 MP, and 120 fps @ 12.5 MP.
These smartphones benefit from the HP9's impressive light sensitivity, vivid color reproduction, and improved focus, making these two smartphones stand out in mobile photography.
2. ISOCELL GNJ

The GNJ is a dual pixel sensor with 50 million 1.0-micrometer pixels in a 1/1.57-inch optical format. Each pixel houses two photodiodes, enabling fast and accurate autofocus, similar to human eyes. This sensor enhances overall imaging performance in smartphones.
Each pixel houses two photodiodes, enabling fast and accurate autofocus, similar to the way human eyes focus. The image sensor also simultaneously captures full color information for quick focusing with sustained image quality.
The GNJ combines dual pixel technology with an in-sensor zoom function to deliver clearer footage in video mode and higher-resolution images free from artifacts or moiré2 patterns in photo mode.
3. ISOCELL JN5:

The ISOCELL JN5 features 50 million 0.64μm pixels in a 1/2.76-inch optical format.
Dual vertical transfer gate (Dual VTG) technology increases charge transfer within pixels, substantially reducing noise in extreme low light conditions for clearer image quality.
Leveraging Super Quad Phase Detection (Super QPD), the JN5 adjusts focus by comparing phase differences both vertically and horizontally, catching even the smallest details of rapidly moving objects with minimal shake.
Additionally, the JN5 incorporates dual slope gain (DSG) technology to enhance its HDR. This technology amplifies the analog light information entering the pixels into two signals, converts them into digital, and then combines them into one data, expanding the range of colors that the sensor can produce.
