The Samsung ISOCELL HP2 sensor, which is used in the Galaxy S23 Ultra and potentially in other models like the Galaxy S25 Edge (though the S25 Edge is rumored to use the ISOCELL HP5 for its main camera), offers several unique features that enhance its performance and capabilities:
1. Pixel Size and Format: The ISOCELL HP2 sensor features 200 million 0.6-micrometer (μm) pixels in a 1/1.3-inch optical format. This size is typically found in 108MP main smartphone cameras, allowing for a higher resolution without a large camera bump[1][4].
2. Tetra²pixel Technology: This technology allows the sensor to merge up to 16 pixels into one, effectively creating larger pixels for better low-light performance. It can operate as a 1.2μm or 2.4μm unit pixel, providing flexibility in different lighting conditions[4][9].
3. Dual Vertical Transfer Gate (D-VTG): This technology enhances the full well capacity of each pixel, allowing it to capture more light before clipping. It helps prevent blown highlights and improves color reproduction, especially in bright conditions[1][4].
4. Super QPD (Quad Phase Detection): This feature enables fast and accurate autofocus even in low-light environments by recognizing both horizontal and vertical patterns. It supports capturing moving objects with high frame rates[4][9].
5. Dual Slope Gain (DSG): In 50MP mode, the ISOCELL HP2 applies two separate conversion values to the analog signal received at the pixel level. This results in "super HDR performance," capturing images with detailed shadows and highlights without the risk of detail loss typically seen in conventional HDR modes[1][4].
6. ISOCELL Zoom Anyplace: This feature uses AI to track and film a selected subject, allowing for seamless zooming without losing resolution. It supports real-time remosaic capabilities, enabling the capture of both full-screen and zoomed-in views simultaneously[7].
However, it's worth noting that the Galaxy S25 Edge is rumored to use the ISOCELL HP5 sensor for its main camera, not the ISOCELL HP2[2]. The ISOCELL HP5 sensor is expected to have its own set of features tailored for the S25 Edge's camera setup.
