Samsung has introduced ISOCELL HP1 and ISOCELL GN5 image sensors. The ISOCELL HP1 is equipped with a 200 megapixel image sensor with 0.64 micron pixels and a new pixel binning technology called Chameleon Cell. The ISOCELL GN5 is considered the first image sensor to adopt Dual Pixel Pro fully directional focusing technology with two photodiodes in a single 1.0 micron pixel. It’s a super-thin 1.0 micron, 50 megapixel sensor that delivers ultra-fast autofocus. Samsung claims Samsung ISOCELL HP1 and ISOCELL GN5 samples are available to suppliers.
The Samsung ISOCELL HP1 sensor is considered the first mobile sensor to support 200 megapixels. It is based on Samsung’s advanced 0.64 micron pixels to deliver ultra-high resolution in a small smartphone package. The company says the ISOCELL HP1 can record 8K videos at 30fps with minimal loss in field of view.
Samsung ISOCELL HP1 introduces a new Chameleon Cell technology, a pixel-binning technology that uses a two-by-two, four-by-four, or full-pixel layout, depending on the environment. In low light, the HP1 switches to a 12.5 megapixel image sensor with pixels large at 2.56 microns, blending together 16 neighboring pixels. The newly formed 2.56 micron pixel is capable of greater light absorption and sensitivity, producing clearer, brighter photos indoors or at night.
In bright outdoor environments, the sensor’s 200 million pixels can capture ultra-high definition stills on smartphones. Samsung ISOCELL HP1 merges four neighboring pixels to reduce resolution to 50 megapixels or 8,192×6,144 pixels to record 8K videos (7,680×4,320 pixels) without the need to crop or reduce the total image resolution.
Coming to the Samsung ISOCELL GN5 sensor, it is said to be the first 1.0 micron image sensor to integrate Dual Pixel Pro fully directional autofocus technology for ultra-fast autofocus. New Dual Pixel Pro technology places two photodiodes within each 1.0 micron pixel of the sensor horizontally or vertically to recognize pattern changes in all directions. With a million multi-directional phase-detection photodiodes covering all areas of the sensor, the ISOCELL GN5’s autofocus becomes instantaneous, allowing for sharper images in bright or dimly lit environments.
In addition, Samsung claims that the image sensor also uses Samsung’s Deep Front Trench Isolation (FDTI) to allow each photodiode to absorb and retain more light information, improving total photodiode capability (FWC) and decreasing crosstalk inside the pixel.
We can expect these sensors to be delivered on smartphones in late 2021 or early 2022. Samsung may also introduce the ISOCELL HP1 sensor in its supposed flagship Samsung Galaxy S22 series.
