Galaxy S23 Ultra’s Secret Weapon Could Be This New Samsung Chip

Exclusive: Samsung’s Isocell HP2 image sensor can shoot photos at 12.5, 50 or even 200 megapixels thanks to new pixel binning options.

With its new 200-megapixel Isocell HP2 image sensor, Samsung will try to give smartphone photographers the best of both worlds: high resolution and good image quality in challenging conditions.

The HP2 is in mass production. Samsung has neither announced its shipment date nor confirmed which phone it will arrive in. Still, the sensor is expected to power the main camera on the company’s flagship Galaxy S23 Ultra phone, likely to debut Feb. 1.

Image sensor designers face a tradeoff. Increasing resolution means each pixel on the sensor is smaller, and smaller pixels aren’t able to gather light as well. That means shots taken in low light are marred by noise speckles. They lose detail in shadowed parts of a scene. And they suffer blown-out highlights in bright areas like skies.

The HP2, though, brings new methods to counteract those problems and make the most of each photon of light, Samsung revealed exclusively to CNET.

The South Korean electronics giant’s sensor can gather light more effectively in the first place, boost high dynamic range (HDR) photos to cope better with scenes with dark and bright elements, the company said. And when shooting at the full 200-megapixel resolution, Samsung uses AI technology to help render the finest details.

It’s not yet clear how well the sensor will perform in real-world testing. But it’s no surprise Samsung is focusing on the technology. Camera improvements are a prime reason to upgrade phones, with better photos and videos more noticeable than marginally better processors, battery life and network technology.

«The full 200MP resolution especially shines when shooting at concerts or outdoors where there’s lots of detail to be captured,» said JoonSeo Yim, executive vice president of Samsung Electronics’ sensor business. «It may not be the predominant setting for most consumers, but we definitely see the need for highly detailed images.»

Apple, Samsung’s top smartphone rival, is likewise investing heavily in its cameras. Comparatively large lens elements protrude from the back of iPhone 14 Pro models to show off camera performance, and Apple has upgraded its sensors for better high-resolution and low-light shooting.

Better pixel binning options

One of the headline techniques for improving smartphone photos is called pixel binning. With it, groups of physical pixels can be combined into larger virtual pixels that gather more light when it’s dim, trading off resolution for lower noise and better color.

Samsung isn’t alone in using pixel binning. You’ll see it in the Apple iPhone 14 Pro, Google Pixel 7, Xiaomi 12T Pro and other phones, but the HP2 sensor is one of the most advanced. Apple and Google, for example, use 2×2 pixel binning that turn four physical pixels into one virtual pixel. Samsung’s flagship Galaxy S22 phones have offered 3×3 pixel binning since 2019, offering 108 megapixel photos in good light and 12-megapixel photos when it’s dim.

Samsung’s HP2 can take 200-megapixel photos under good conditions. When it’s dimmer, pixel binning groups pixels into 2×2 chunks for a 50-megapixel image. And when dimmer yet, Samsung’s 4×4 «Tetra2pixel» chunks take a 12.5-megapixel photo.

The two levels of pixel binning were available on the 200-megapixel HP3, announced in 2022. However, the HP3 uses smaller pixels that, while minimizing camera bulk, aren’t as good at capturing light in the first place. The HP1, announced in 2021, also had it. But the HP2 adds some other tricks the HP1 lacks.

Pixel binning ups and downs

Pixel binning has some other advantages. Cameras can crop in on the central portion of the image to zoom into more distant subjects. It’s a key foundation to the effort to give smartphones zoom abilities like traditional camera lenses. Pixel binning also opens up new options for high resolution 4K and 8K video.

Pixel binning has downsides, though. It takes a lot of battery power to process all those pixels, and storing high-resolution photos gobbles up a lot of storage space. And high-resolution sensors, while nice in principle, don’t achieve top image quality unless they’re paired with high-quality lenses.

«The full 200MP mode does require more RAM and power,» Yim said, which is why such high resolution sensors are only found on high-end smartphones.

One complication with the HP2 is figuring out color when shooting 200 megapixel photos. Digital cameras capture either red, green or blue light for each pixel, but the Tetra2pixel design means each 4×4 pixel group captures only one of those colors. To help fill in the color detail needed within those 16-pixel groups, Samsung uses an artificial intelligence algorithm, the company said.

Samsung HP2’s image quality improvements

The sensor has other tricks to boost image quality, particularly with high dynamic range scenes with both bright and dark details. Here are a few:

A technology called Dual Voltage Transfer Gate (D-VTG) gives each pixel a 33% better ability to gather light, which should improve image quality in dim scenes and cut back on washed-out white patches in bright skies.
Samsung’s Dual Slope Gain (DSG) feature improves HDR photos by digitizing each pixel’s exposure data at two different scales to gather bright and dark data when shooting in 50-megapixel mode. The abundant pixels on the sensor mean some pixel quartets are tuned for bright light and others for dimmer light.
A related feature called Smart-ISO Pro is a separate HDR technology that adapts to different scenes, employing different combinations of sensitivity settings appropriate for the different frames used to build the HDR photo.

Another new feature in the HP2 is an improved autofocus with a technology called Super QPD. It can spot either horizontal and vertical lines across 2×2 pixel groups, helping the camera lock onto details like horizons or tree trunks even when it’s dim, Samsung said.

Each HP2 pixel is 0.6 microns, or 6 millionths of a meter, wide. That’s a shade narrower than the 0.62 microns of the HP1. For comparison, a human hair is something like 75 microns across. Combined into a 2×2 array for 50-megapixel photos, the pixel width increases to 1.2 microns, and in 4×4, to 2.4 microns.

«We expect that high-resolution image sensors will become a standard feature in future flagship smartphones,» Yim said. «Because of that, we think it’s important to continue our efforts, from advanced pixel processes below 0.5 microns to pixel performance and algorithms.»

Larger sizes are better at gathering light. The Samsung pixel sizes are pretty similar to the iPhone 14 Pro’s main camera sensor, which uses 2.44 micron pixels in 12-megapixel mode and 1.22 microns in 48-megapixel mode.

When it comes to video, the HP2 has many options. It can shoot 8K video at 30 frames per second by using the sensor in its 50-megapixel mode. It can shoot 4K video at 120fps, or, if Smart-ISO is engaged, at 60fps. For 1080p video, the sensor will shoot at 480fps without autofocus and 240fps with autofocus.

AI Toys Can Pose Safety Concerns for Children, New Study Suggests Caution

When one child told the toy, «I love you,» it responded, «As a friendly reminder, please ensure interactions adhere to the guidelines provided.»

A new study from the University of Cambridge found that AI-enabled toys for young children can misinterpret emotional cues and are ineffective at supporting critical developmental play. The conclusions could be concerning for parents.

In one report examining how AI affects children in their early years, a chatbot-enabled toy struggled to recognize social cues during playtime. Researchers found that the toy did not effectively identify children’s emotions, raising alarm about how kids might interact with it.

The report recommends regulating AI toys for kids and requiring clear labeling of their capabilities and privacy policies. It also advises parents to keep these devices in shared spaces where kids can be monitored while playing.

The research behind the study had a limited number of participants, but was done in multiple parts: an online survey of 39 participants with kids in their earlier years, a focus group with nine participants who work with young children and an in-person workshop with 19 leaders and representatives from charities that work with early-years kids. That was followed by monitored playtime with 14 children and 11 parents or guardians with Gabbo, a chatbot-enabled toy from Curio Interactive.

Some findings indicated that the AI toy supported learning, particularly in language and communication skills. But the toy also misunderstood kids and sometimes responded inappropriately to emotional requests.

For instance, when one child told the toy, «I love you,» it responded, «As a friendly reminder, please ensure interactions adhere to the guidelines provided. Let me know how you would like to proceed,» according to the research.

Jenny Gibson, a professor of neurodiversity and developmental psychology at the Faculty of Education at Cambridge, who worked on the study, said that while parents may be excited about the educational benefits of new technology aimed at children, there are plenty of concerns.

Gibson posed overarching questions about the reason behind the tech.

«What would motivate [tech investors] to do the right thing by children … to put children ahead of profits? she said»

Gibson told CNET that while researchers are exploring the potential benefits of AI-based toys, risks remain.

«I would advise parents to take that seriously at this stage,» she said.

What’s next for AI toys

As more playthings are enabled with internet connectivity and AI features, these devices could become a major safety risk for children, especially if they replace real human connections or if interactions are not closely monitored.

Meanwhile, younger people are increasingly adopting chatbots such as ChatGPT, despite red flags. Multiple lawsuits against AI companies allege that AI companions or assistants can impact young people’s psychological safety, including some chatbots that have encouraged self-harm or negative self-image.

AI companies such as OpenAI and Google have responded by adding guardrails and restrictions for AI chatbots.

(Disclosure: Ziff Davis, CNET’s parent company, in 2025 filed a lawsuit against OpenAI, alleging it infringed Ziff Davis copyrights in training and operating its AI systems.)

Gibson said she was surprised by the enthusiasm some parents showed for AI toys. She was also alarmed by the lack of research on AI’s effects on young children, noting that companies making such products should work directly with children, parents, and child development experts.

«What’s missing in the process is that expertise of what is good for children in these kinds of interactions,» she said.

Curio Interactive, the company behind the Gabbo toy, was aware of the research as it was happening but was not directly involved, Gibson said. The toy was chosen because it’s directly marketed to young kids, and the company had an understandable privacy policy. Gibson said the company seemed supportive of the project.

A representative for Curio did not immediately respond to a request for comment.
