Samsung Introduces the 200-Megapixel Image Sensor in Flagship Smartphones

Samsung Electronics recently introduced its latest 200-megapixel (MP) image sensor, the
ISOCELL HP2, with improved pixel technology and full-well capacity for stunning mobile images
in tomorrow’s premium smartphones.
“The Samsung ISOCELL HP2 harnesses Samsung’s high-resolution image sensor technologies
and know-how at the cutting edge for epic details,” said JoonSeo Yim, Executive Vice President
of Sensor Business Team at Samsung Electronics. “Our leadership comes from innovative pixel
technologies that allow our sensors to go beyond the number and size of pixels. We will
continue to open new horizons and solidify our presence in the expanding ultra-high-resolution
sensor market.”
The ISOCELL HP2 packs 200-million 0.6-micrometer (μm) pixels in a 1/1.3” optical format, a
sensor size that is widely used in 108MP main smartphone cameras. This enables consumers
to enjoy even higher resolutions in the latest high-end smartphones without larger camera
bumps in their devices.
With Samsung’s advanced pixel-binning technology, Tetra2pixel, the HP2 adds more versatility
to the camera as it simulates different pixel sizes to accommodate varying lighting levels. When
in low-lit environments, the sensor transforms either into a 1.2μm 50MP or 2.4μm 12.5MP
image sensor by binding four to 16 neighboring pixels. For fuller 8K video, approximately at
33MP, the HP2 switches to 1.2μm 50MP mode to minimize cropping and capture more of the
scene. Filming 8K at 30 frames-per-second (fps), a wide field of view along with bigger pixel
size can produce sharp cinematic videos.
Washed out pictures from brightly lit environments can be significantly reduced with the HP2,
thanks to Samsung’s new Dual Vertical Transfer Gate (D-VTG) technology. In a photo diode
within each pixel, a voltage transfer gate is placed on the bottom to transport electrons from the
pixels to the logic layer. With high precision, D-VTG adds a second transfer gate in the pixel,
boosting the pixel’s full-well capacity by more than 33 percent. With more electrons stored and
efficient signal transfers, this method can reduce overexposure and enhance color reproduction,
especially in bright light conditions.
In low-lit settings, the HP2’s auto-focusing is taken to the next level with Super QPD, which
allows the sensor to use all its 200-million pixels for focusing agents. The ample amount of
focusing agents are grouped by four adjacent pixels to recognize both horizontal and vertical
pattern changes that delivers faster and more accurate auto-focusing. Utilizing the rich pattern
data along with the sheer number of reference points, the new sensor is capable of fast auto-
focusing, even in a dimly lit environment.
For superb HDR performance, Samsung is introducing the DSG feature for the first time in
50MP mode which applies two separate conversion values to the analog signal received at the
pixel level. In addition, the Smart-ISO Pro, an HDR solution that merges different levels of ISO

readouts from a single exposure, allows the camera to take 12.5MP images and 4K at 60fps
video in HDR.
In Sri Lanka, Samsung has been recognized as the ‘Most Loved Electronics Brand’ for three
consecutive years by Brand Finance Lanka’s review of the country’s most valuable brands. As
Sri Lanka’s No.1 smartphone brand, Samsung’s customer base in the country spans across all
age groups, particularly the Gen Z and Millennial segments.
