Samsung Unveils the World’s First 200MP Mobile Image Sensor
After taking the wraps off its 108MP ISOCELL HM3 image sensor earlier this year, Samsung unveiled two new image sensors today. Among these, the first is the ISOCELL HP1 sensor, which is the world’s first 200MP mobile image sensor. The other is the 50MP ISOCELL GN5 image sensor.
The company has shared details of its latest image sensors via a official blog. Industry-first 200MP sensor features tiny 0.64 micron sized pixels and offers support for 8K videos on mobile and portable devices. The 50MP GN5 sensor, on the other hand, is a lower end sensor with improved auto-focus characteristics.
Samsung 200MP ISOCELL HP1 Image Sensor
Now getting into the technical details of the 200MP sensor, it’s based on the company’s most cutting-edge camera technologies and features an all-new pixel binning technology dubbed the ChameleonCell technology. This pixel binning technology uses two-by-two, four-by-four, or the layout of pixels for full images depending on ambient lighting.
Therefore, in low-light environments, the ISOCELL HP1 coils in an image sensor with a large 12.5MP 2.56μm pixel. he basically 16 merge neighboring pixels to pick up the lighter and increase sensitivity. It allows users to capture bright and crisp images indoors and in dimly lit situations. The sensor, however, performs at full capacity in bright outdoor environments and delivers ultra-high definition images on mobile devices.
As for video capability, the 200MP ISOCELL HP1 supports 8K video recording at 30fps. The sensor allows minimal loss in the field of vision. Moreover, it merges four neighboring pixels to lower the resolution of videos to 50MP to capture 8K videos without cropping or reducing the full resolution of the image.
Samsung 50MP ISOCELL GN5 Image Sensor
Coming to the ISOCELL GN5 image sensor, the 50MP sensor is the industry’s first image sensor to come with built-in support for Dual Pixel Pro technology. This is essentially advanced technology that allows the sensor to focus automatically in all directions.
Dual Pixel Pro technology utilizes two of the industry’s smallest photodiodes between each 1um pixel. These photodiodes are either placed horizontally or vertically between pixels to account for configuration changes in all directions. So, with a million of these phase-detection photodiodes, the 50MP ISOCELL GN5 sensor is able to auto-focus instantly in both bright and low-light environments.
In addition, the GN5 image sensor also uses the company’s proprietary pixel technology that applies deep front trench isolation (FDTI). This makes it the first dual pixel product in the industry to apply FDTI technology. It essentially allows the tiny photodiodes between the pixels to absorb and retain more light information, despite their micro-sized form factor.
Now, coming to the availability of the new image sensors, Samsung is already shipping ISOCELL and HP1 GN5 image sensors to OEMs. So we can expect phone makers to launch phones with these sensors in late 2021 or early 2022.
