Here’s how Galaxy HDR works on the latest Samsung Galaxy S23
Samsung Galaxy S23 series comes with a new design, new features, and the latest software. In addition, the Galaxy S23 series shows Samsung’s groundbreaking photographic capabilities such as stand-out selfies, cinematic video with less noise even in dark conditions, Auto Exposure with HDR, detailed photos, and more.
Let’s talk about the Galaxy HDR technology implemented in the Galaxy S23 series. But do you know what HDR is? If you do not know, then let us tell you that HDR (High Dynamic Range) is a technology that expresses bright and dark areas as widely as possible.

When we take pictures or videos, we get images with suitable brightness through AE (Auto Exposure) operation which adjusts the exposure. However, when shooting indoors in backlit conditions or while looking out a window, bright and dark scenes coexist, resulting in images that are bright or dark depending on the scene.
Samsung Galaxy S23 HDR Technology
In Samsung Galaxy S23, the company uses the MF-HDR (Multiple Frame HDR) compositing method. It is a technology that takes pictures of different brightness by continuously adjusting the exposure, and then extracts the video information of the bright part from the bright picture and the video information of the dark part from the dark picture, and combines them into one picture.
Since the image is created by selectively combining bright and dark object information, an image with optimal brightness is created. However, since MF-HDR captures multiple consecutive scenes, there is a lag between scenes.
It means that a moving subject is prone to ghosting when the motion vector and image overlap, so it is recommended to use it in a shooting mode where the subject moves little.
On the flip side, in motion picture mode, SF-HDR (single-frame HDR) technology is applied, and image sensor IDCG (Intrascene Dual Coverage Gain) technology is used to capture and synthesize bright and dark scenes simultaneously.
Image sensor iDCG technology generates electrons, that is, electrical signals, according to the brightness when light is incident on the photodiode of the image sensor, and the image sensor’s internal circuit (ADC: Analog Digital Converter and Logic Circuit) is used to convert the image sensor does for voltage. It goes through a process of change.
During the conversion of light into an electrical signal, electrons are placed in a cup called FD (Floating Diffusion) to measure the number of electrons. Determine a specific ratio based on the capacity of the cup and convert it to a voltage signal.
In the case of existing sensors, the capacity of the cup is limited to one, so it is difficult to take great pictures in environments with frequent changes in light and dark.
If the cup potential is large in a dark environment, it will be difficult to clearly express the dark part because the small light information cannot be converted into a sufficient voltage. It’s hard to articulate the bright parts well.
iDCG technology converts the existing one cup into two cups of different capacities, selects the smaller cup in a dark environment, selects the larger cup in a bright environment, measures twice, synthesizes in real-time, and HDR improves the performance of the image.
In the case of SF-HDR using 1 exposure, it is better for shooting moving images than MF-HDR using 2 exposures because of the sharpness of the subject’s movement. In addition to this, the company is preparing to bring HDR performance closer to the human eye through camera image sensors and ISP technology.
Samsung and Apple are the biggest rivals in the smartphone industry, fighting for the global crown. Apple has mastery in some aspects such as longer updates support and well-optimized software, while it’s nothing without the help of Samsung for displays.
According to a TheInformation report, there are complicated relationships in the tech industry and then there is the rocky marriage between Apple and Samsung for displays. The former needs cutting-edge displays for iPhones which makes it dependent on Samsung, while it blames Samsung for patent infringement.

An ex-Apple employee revealed how Samsung is concerned to protect its display technology supremacy. The company naturally wishes to keep the biggest rival away from its cutting-edge display technology, by preventing Apple engineers to visit manufacturing facilities.
It’s reported that a team of Apple engineers went to South Korea to meet the Samsung display division’s team in 2017. Instead of a meeting, the company didn’t allow the workers to reach the display manufacturing units and even the office buildings.
Samsung reportedly asked Apple employees to return to their hotel rooms to communicate with their Samsung counterparts remotely. In addition, an incident happened in the past when Samsung was sending millions of LCD displays to Foxconn to be utilized in the Retina version of the iPad mini.
The US tech giant reportedly found a few minor defects in the screens, but Samsung declined to amend them, so Apple had to go ahead and deploy the supplied panels. No doubt, Samsung achieved mastery in display technology, which forces Apple to keep this unhappiest marriage alive.
Samsung is the biggest supplier for Apple’s iPhone 14 Pro panel orders, beating LG Display and China’s BOE. For the next-gen iPhone models, it is reported that the Korean tech giant will have a sweeping order from Apple, thanks to the ultimate OLED panels!

Last year, Samsung launched its first Ultra tablet with a monster size display and powerful hardware. And it’s now almost confirmed that Samsung will launch the Galaxy Tab S9 Ultra along with the vanilla Galaxy Tab S9 and Galaxy Tab S9 Plus.
Folks over at GalaxyClub revealed that the Samsung Galaxy Tab S9 series consists of three models including vanilla, Plus, and Ultra. It’s also reported that the upcoming flagship tablet lineup will make its entry at the Galaxy Z Fold 5 and Flip 5 launch conference.
Galaxy Tab S9 model numbers
- Galaxy Tab S9: SM-X710 (Wi-Fi), SM-X716B (5G Global), SM-X718U (5G US)
- Galaxy Tab S9+: SM-X810 (Wi-Fi), SM-X816B (5G Global), SM-X818U (5G US)
- Galaxy Tab S9 Ultra: SM-X910 (Wi-Fi), SM-X916B (5G Global), SM-X918U (5G US)
As per the report, all three Galaxy Tab S9 models will be available in WiFi-only and WiFi + 5G network support. Like last year, the US availability of these tablets is almost confirmed, while there’s currently no information about further details and price.
In the recent past, it was revealed that the Galaxy Tab S9 devices feature the IP67 rating for dust and water resistance. It’s a big development by Samsung for its tablet portfolio as it’s going to be the first time when Galaxy tablets would support IP rating.
Apart from Android 13-based One UI 5.1.1 software, the Galaxy Tab S9 lineup is rumored to bring Qualcomm’s latest Snapdragon 8 Gen 2 for Galaxy processor. Compared to predecessors, the devices should feature better cameras, enhanced speakers, and refined performance.
At the Galaxy Unpacked, Samsung revealed that it’s working in collaboration with Qualcomm and Google to develop “extended reality” hardware in the near future. And recently, Samsung filed new trademarks with the US authority for “Galaxy Glasses” AR/VR headsets and “Galaxy Ring” smart rings.
Galaxy Glasses
The trademark reveals the brand name “Galaxy Glasses” which comes as the first fruitful outcome of Samsung and its friends. The name alone evokes smart glasses similar to Focals by North or the Ray-Ban Stories, while the full application also covers “headsets” for both AR and VR use.
GALAXY GLASSES™ trademark registration is intended to cover the categories of virtual reality headsets; Augmented reality headsets; Headphones; Smartphones; Smart glasses.
By submitting trademark applications, the South Korean tech giant indicates that it’s quite serious about the growth of this product portfolio. However, there is no confirmation or input on whether Samsung will bring slim smart glasses or a full-on VR headset experience.
Galaxy Ring
Galaxy Ring is the second trademark application filed by Samsung Electronics. The document description reveals that the Galaxy Ring device would collect health, fitness, and sleep data, in order to end the need of wearing a fitness tracker on the wrist.
SAMSUNG GALAXY RING™ trademark registration is intended to cover the categories of wearable smart devices in the nature of a smart ring for tracking, measuring, monitoring, and uploading health, fitness and sleep related information; smart rings; smartphones.
Since Samsung has not yet officially disclosed its plans for extended reality products, we have to wait for an official confirmation. It’s also a mystery whether the Samsung Galaxy Glasses and Ring are related to each other or will be commercialized as separate products.
