Samsung has officially announced that it is producing a mobile phone sensor with a whopping 200 megapixels - setting a new record for cellphone camera resolution. The Samsung Isocell HP1 uses photosites that measure just 0.64μm across - the same size as found in Samsung's own JN1 50MP chip that was introduced earlier this year.
The jump in pixel count is designed to use with Samsung's improved pixel binning technology - that clusters photosites together to increase image performance. The company says that its all-new ChameleonCell technology deploys a pixel-binning algorithm that uses a two-by-two, four-by-four or full pixel layout depending on the environment. Furthermore, in lowlight, the HP1 transforms into a 12.5MP image sensor with large 2.56μm pixels by merging 16 neighboring pixels.
The Isocell HP1 image sensor can shoot 8K videos at 30fps with minimum loss in the field of view, the company says, by merging four neighboring pixels to bring the resolution down to 50MP or 8,192 x 6,144 to take 8K (7,680 x 4,320) videos without the need to crop or scale down the full image resolution.
The new 200 megapixel sensor is already expected to be used in Xiaomi's next flagship mobile phone, according to recent rumors. There has also been speculation that Samsung may use this new sensor on the Samsung Galaxy S22 Ultra, that industry pundits expect to be announced later this year - but could well not actually be put into action by Samsung until 2022.

Also announced by Samsung Electronics semiconductor division is the Isocell GN5, which claims to be the industry’s first 1.0μm image sensor to integrate Dual Pixel Pro - which is designed to boost autofocus performance.
This technology places two photodiodes, within each 1.0μm photosite of the sensor either horizontally or vertically to recognize pattern changes in all directions. With one million phase-detecting multi-directional photodiodes covering all areas of the sensor, the sensor’s autofocusing is described as "instantaneous, enabling sharper images in either bright or low-lit environments".
The image sensor applies Front Deep Trench Isolation (FDTI) on a Dual Pixel product for the first time in the industry. Despite the microscopic photodiode size, FDTI enables each photodiode to absorb and hold more light information, improving the photodiodes’ full-well capacity (FWC) and decreasing crosstalk within the pixel.
