Advanced image sensors for next-generation mobile imaging
Samsung Electronics has introduced two new mobile image sensors offering advanced ultra-fine pixel technologies.

The ISOCELL HP1 is offered as the industry’s first 200-megapixel (MP) image sensor with 0.64µm pixels, while the ISOCELL GN5 is the first image sensor to adopt all-directional focusing Dual Pixel Pro technology with two photodiodes in a single 1.0µm pixel.

“Samsung has been pioneering ultrafine pixel technologies that are taking high-resolution image sensors to the next level,” says Duckhyun Chang, executive vice president of sensor business at Samsung Electronics. “With the ISOCELL HP1 that is breaking barriers and ISOCELL GN5 bringing ultrafast auto focus, Samsung will continue to lead the trend for next-generation mobile imaging technologies.”

Based on Samsung’s most advanced 0.64µm-sized pixels and offered as the industry’s first mobile image sensor to support 200MP, the ISOCELL HP1 brings ultra-high resolution in a small package that fits comfortably in today’s handheld devices. With the ISOCELL HP1, says the company, pictures hold an astonishing amount of detail that helps the image stay sharp even when cropped or resized.

For ultimate low-light photography, the ISOCELL HP1 features an all-new ChameleonCell technology - a pixel-binning technology that uses a two-by-two, four-by-four, or full pixel layout depending on the environment. In a low-lit environment, the HP1 transforms into a 12.5MP image sensor with large 2.56µm pixels by merging 16 neighboring pixels. The newly formed 2.56µm pixel is capable of more light absorption and sensitivity, producing brighter and clearer photos in indoors or in the evening. In bright outdoor environments, the sensor’s 200-million pixels can capture ultra-high-definition photography on mobile devices.

The ISOCELL HP1 can take 8K videos at 30 frames-per-second (fps) with minimum loss in the field of view. The HP1 merges 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 second device, the ISOCELL GN5, is offered as the industry’s first 1.0µm image sensor to integrate Dual
