Samsung has announced the ISCOCELL HPX, a new 200MP sensor in China. This follows the June announcement of the ISOCELL HP3 200MP sensor. The ISOCELL HPX has 0.56-micron pixel size, which can reduce the camera module area by 20%, making the smartphone body thinner and smaller.
Furthermore, Samsung employed Advanced DTI (Deep Trench Isolation) technology, which not only separates each pixel individually, but also increases sensitivity to capture crisp and vivid images. Furthermore, the Super QPD autofocus solution enables ISOCELL HPX to have ultra-fast and ultra-precise autofocus.
Tetra-Pixel technology in ISOCELL HPX sensor
Additionally, the Tetra pixel (16 pixels in one) technology is used in this new sensor that will give positive shooting experience in low light. With the help of this technology, the ISOCELL HPX is able to automatically switch between three different lighting modes depending on the available light: in a well-lit environment, the pixel size is maintained at 0.56 microns (μm), rendering 200 million pixels; in a low-light environment, the pixel is converted to 1.12 microns (μm), rendering 50 million pixels; and in a low-light environment, 16 pixels are combined to create a 2.24 micron (μm) 12.5 million pixel sensor.
According to Samsung, this technology enables ISOCELL HPX to deliver a positive shooting experience in low light and to reproduce sharp, sharp images as much as possible, even when the light source is constrained.
The ISOCELL HPX supports seamless dual HDR shooting in 4K and FHD modes and can capture 8K video at 30 fps. Depending on the shooting environment, Staggered HDR, according to Samsung, captures shadows and bright lights in a scene at three different exposures: low, medium, and high. Then it’ll combine all three exposure photos to produce HDR images and videos of the highest quality.
Additionally, it enables the sensor to render the image at over 4 trillion colours (14-bit colour depth), which is 64 times more than Samsung’s forerunner’s 68 billion colours (12-bit colour depth).
There’s no official wording from the firm regarding the availability. We should know in the coming weeks.

I wonder if the color filter array is fixed, how does a 'red' or 'blue' filter to be treated as 'green' when binning as illustrated in the figure above.
ReplyDeleteThat's a fundamental suspicion about remosaicing.
DeleteWhen sensor manufacturers show pixel arrays with filters, they always show sharp boundaries between adjacent colors. This is how the filters are fabricated, but it is not the effective coverage of the pixels after demosaicing, which smears the boundaries over two or three pixels and produces overlaps. Remosaicing doesn't do anything with the physical filters, it just changes the demosaicing arithmetic by taking more pixels into the calculation, producing a little lower noise and more smear.

Does someone know what's the difference with HP3 as 200M, 0.56um pixel (tetra design)?
