The source said that the ISOCELL HW1 will have a 1/1.05-inch, single-pixel point of 0.56μm, and can reach a resolution of 432 megapixels.

The ISOCELL HW2 will be 1/1.07 inches with 0.5μm individual pixels and the same 432MP resolution.

@Tech_Reve did not reveal the launch date of the ISOCELL HW series of sensors. In the same tweet, it was stated that the Galaxy Z Fold 6 will continue to use the GN3 sensor, while the Galaxy Z Fold 7 will only use the S5KHP5 sensor.

The ISOCELL HP2 has a 0.6 micron (μm) sensor size in a 1/1.3-inch optical format that can accommodate 200 million pixels.

With Samsung’s pixel merging technology, Tetra²pixel (Sixteen-in-One Pixel Technology), the HP2 can simulate different pixel sizes to accommodate different light levels, making the camera useful in more scenarios, Samsung said. In low light conditions, the HP2 converts the sensor to a 1.2-micron (μm) 50-megapixel (50MP) or 2.4-micron (μm) 12.5-megapixel (12.5MP) image sensor by merging four to 16 adjacent pixels.

If one wishes to shoot full 8K video at approximately 33 megapixels (33 MP) pixels, the HP2 will switch to 1.2 microns 50-megapixel mode to facilitate minimizing frame loss and capturing more detail in the scene.

Thanks to Samsung’s new Dual Vertical Transmission Gate (D-VTG) technology, the HP2 is said to be able to reduce the problem of overexposure of photos in bright light conditions. A voltage transmission gate is set at the bottom of the photodiode within each pixel to transfer electrons from the pixel to the logic layer. d-VTG also adds a second transmission gate in the pixel exactly, increasing the pixel’s full well capacity by more than 33%. By absorbing more electrons and efficient signaling, this approach reduces overexposure and enhances color reproduction.

Samsung notes that the Super QPD (Super QPD Autofocus Solution) solution allows the HP2 to fully engage 200 million pixels for focusing in low-light conditions. In addition, the HP2 uses four adjacent pixels to recognize horizontal and vertical pattern changes. Even in dim conditions down to 1 lux (lux), the new HP2 sensor can recall pattern data and reference points to quickly autofocus on a target subject.

With a frame rate of 15 frames per second (fps), the HP2 can support ultra-high resolution photos from mobile devices with less shutter lag than Samsung’s predecessor.

To take advantage of HDR (High Dynamic Range) performance, Samsung has introduced a DSG function in the 50-megapixel (50MP) mode, which applies two separate conversion values to analog signals received at the pixel level. In addition, the HDR solution Smart ISO Pro, which can combine two high, medium and low ISO readings from a single exposure, allows the camera to capture 12.5-megapixel images and 60fps 4K video in HDR.

Currently, Samsung ISOCELL HP2 is in the process of mass production.

Interestingly, the name of the sensor on next year’s Galaxy flagships is still ISOCELL HP2, despite the HP3 model already being available.

The ISOCELL HP1 was the first 200-megapixel sensor, and we expect to see it debut in a Motorola smartphone this month. ISOCELL HP3 follows suit with a smaller sensor area of 1/1.4 inches, but faster autofocus thanks to a new design for each pixel, which features autofocus with each quad-pixel block group recognizing vertical and horizontal differences.

This is not the first time we’ve heard that the Galaxy S23 Ultra will receive a 200MP sensor. Another report suggests that while the main camera will be updated, the 10MP 10x periscope module is likely to remain the same.
