In the latest flagship, the Galaxy S23 series’ top-of-the-line Ultra model (Galaxy S23 Ultra), Samsung features its 200MP image sensor- ISOCELL HP2. It is the first time that Samsung has used this big image sensor in its Galaxy phone. The wonderful thing is this new sensor has been made by Samsung itself, which was a really tough task for the manufacturer. Let’s take a look at the journey of the development of this sensor.
Informatively, the Galaxy S23 Ultra’s this new advanced camera sensor capable of lending an incredible photography experience. The sensor will open up opportunities for professional and recreational photographers who want to take their photography to the next level. As per Kyungho Lee, the Vice President of the Pixel Development Team, they had dramatically increased the pixel storage capacity of this sensor.
ISOCELL HP2 200MP Sensor
If you are unaware, the Galaxy S23’s HP2 sensor is capable of capturing pictures in three modes- 12MP, 50MP, and of course, 200MP, depending on their tastes or the lighting conditions. The sensor features Tetra2pixel technology in it that can group 4 or 16 nearby pixels together depending on the lighting condition to produce bright and sharp images even in low-light conditions.
Let us inform you a new technology named Dual Verticle Transfer Gate has also been developed, which is capable of producing images with no ghosting and a wide dynamic range of brightness. Seungjin Lee from Sensor Design adds he has stated in that manner-
“A significant boost in analog-to-digital conversion (ADC) was crucial. Our developers devised a method to overcome this obstacle and applied it to ISOCELL HP2 for the first time, allowing us to anticipate and correct potential mismatches between ADCs in advance. As a result, we were successful in achieving all of our goals for the image sensor’s performance and reliability.”
Better results sure require a lot of efforts
However, making such an advanced and complicated product must not be easy, and the company sure faced many problems developing it. At first, Samsung thought that pixel shrinking had reached its limit, but then it continued to advance its ISOCELL technology, believing that there are no limits to creating new and cutting-edge technologies. Kyungho also made a statement in that manner-
“At Samsung, we devote all these efforts to deliver a camera experience that enables all mobile users to capture their precious moments and priceless events as vividly and clearly as if they were seeing them with their own eyes.” He also said, “As one of the team members who participated in the evaluation process, I would say it is one of the best ultra-high resolution image sensors we have ever released.”

Informatively, the developer team has achieved ISOCELL’s top-class image quality at the 200MP sensor by dramatically increasing the number of electrons that can be packed into each pixel. This new architecture is capable of reducing noise in both 12MP and 50MP modes and provides outstanding quality in both bright and dark environments. Seungjin has given credit for the sensors’ success to their excellent team and said-
“We were able to meet the deadlines and achieve all the desired performance outcomes by properly allocating focus and resources to high-priority objectives.”
The future will be full of surprises
As such bigger image sensors, specifically sensors with more than 100MP, are currently limited, and we are expanding them to expand with the time being. The South Korean firm is planning to strengthen its market leadership in terms of the ultra-hight resolution image sensor category with the help of its best image sensor lineup, including the 108MP, 200MP, and upcoming ones. Undoubtedly, the future will be full of surprises.
Nota bene, Kyungho said, “We are aiming for more pixels than the 576 million known to be the maximum effective pixels in the human retina. Soyoon Choi also predicts-
“If this trend and evolution continue, we’ll see amazing image sensors which perfectly mimic the human eye not only in terms of detail expression but also dynamic range and color reproduction in the near future.”
