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.

Last week, a user-generated Reddit post created controversy on Samsung Space Zoom technology with the blame for producing AI-generated fake images of the Moon. In an email reply to Tom’s Guide, the company confirmed that the AI-derived feature doesn’t apply any image overlaying to the photo.

Here is the official response from Samsung, delivered via email to Tom’s Guide:

“Samsung is committed to delivering best-in-class photo experiences in any condition.

When a user takes a photo of the Moon, the AI-based scene optimization technology recognizes the Moon as the main object and takes multiple shots for multi-frame composition, after which AI enhances the details of the image quality and colors. It does not apply any image overlaying to the photo.

Users can deactivate the AI-based Scene Optimizer, which will disable automatic detail enhancements to the photo taken by the user.”

Samsung Space Zoom Controversy:

A Redditor posted his experiment of testing Samsung phone’s camera feature, especially the Space Zoom and Moon Shot. The user used a downloaded image of the Moon, downscaled it, and blurred it further (mentioned below) to test what changes the artificial intelligence makes.

He displayed the Moon on a monitor and went back to the second corner of the room (to increase the gap) and pointed the camera with the zoom at the monitor. Samsung phone’s AI-based Scene Optimizer feature identified the Moon and optimized the image with sharpness and colors.

There are blames that Samsung is cheating with Space Zoom and Moon Shots by applying an overlay on the image. The reports are completely fake and there’s no cheating in the Space Zoom feature of your Galaxy. Even, the company itself announced the use of Scene Optimizer, starting with the Galaxy S21 series.

Users of both non-Ultra Galaxy S23 devices complain that whenever they capture images using the primary camera, the focussed part looks sharp, while the edges and sides get blurred. Also, it has been reported that the affected models are manufactured in Vietnam.

Seeing complaints by Galaxy S23 users, some Galaxy S22 users said that this problem also exists on their models, however, they have not reported it at that time. However, we suggest you reach out to the authorized Samsung support center and send it for repair if they identify the issue.

Well-known tipster IceUniverse recently revealed that at the end of March 2023, Samsung will release a big camera firmware update for the Galaxy S23 series. Since the devices would celebrate their second monthly birthday on April 1st, Samsung appears to be fixing the emerging problems.

If it is a hardware defect, sending your Samsung phone for repair is the only solution left. Meanwhile, we believe that the company will fix the problem with the next firmware update. Until then, you can continue rocking with your phone using the manual focus feature before hitting the shutter button.

Galaxy S23 and S23 Plus Camera

The Galaxy S23 and Galaxy S23 Plus bring triple rear cameras including a 50-megapixel (F1.8) wide-angle sensor, a 12-megapixel (F2.2) ultrawide, and a 10-megapixel (F2.4) telephoto. The telephoto camera is capable of 3x optical zoom as well as up to 30x digital zoom.

Recently, a user-generated Reddit post has become a controversial thread, claiming that Samsung is cheating with Space Zoom and the Moon shots by using AI. The user used an image of the Moon, went some steps backward, and captured the displayed Moon to check what happens.

Samsung Galaxy Camera uses AI to upscale the image of the Moon so it looks clearer in images. To do so, the company has applied an intelligent method, which consists of shots of a real Moon in all of its shapes. Machine learning helps the shot to be nourished further during processing.

In his Reddit post, the user said that he has downloaded a high-resolution image of the Moon from the internet, downscaled it to 170×170 pixels, and applied a gaussian blur. That way, the user removed all the details of the image of the Moon downloaded from the web.

This technical yet tricky procedure further added the upscaling of the image by 4 times so the phone can consider it as a long-distance natural Moon. The user later full-screened the image on the monitor, turned the room dark, and captured the screen through a Samsung phone from a distance.

The Samsung phone identified the displayed moon as the real Moon and the Artificial Intelligence refined the shot and delivered a clear and vibrant image of the Moon. For the user, it might be the first time to see the AI technique as generally we don’t try to test the camera and space zoom.

There’s nothing like cheating nor Samsung phones are producing fake Moon images. The company already revealed that an intelligent camera technique and different kinds of machine learning work behind the shot so user can get the most adorable variant in Space Zoom.

AI is being used everywhere. What do you think, is Samsung really cheating with Space Zoom? Let us know through Twitter.

Samsung Space Zoom Camera Technology (Moon Shot)

The post Samsung Space Zoom camera uses AI, is it controversial? appeared first on Sammy Fans.

Today, we discuss how your Samsung phone’s Space Zoom photography feature works. Regardless, hardware is the key factor to introduce a huge zooming/magnification range, but, well-optimized software significantly improves the overall experience. That’s what Samsung does, others not.

Way back in 2019, Samsung introduced AI technology to the mobile camera when it launched the Galaxy S10 series. The company developed a Scene Optimizer feature that helps AI to recognize the subject and provide you with the best photography experiences regardless of time and place.

Specifically for Moon photography, Samsung Galaxy S21 series debuted even better optimization with artificial intelligence. Galaxy flagships starting the Galaxy S21 series recognize Moon as the target using learned data, multi-frame synthesis, and deep learning-based AI technology at the time of the shooting.

In addition, a detail improvement engine feature has also been applied, which makes the picture clearer. If you don’t want to capture photos using AI technology, you can do it by just disabling the Scene Optimizer from the camera viewfinder.

Data learning process for Moon recognition engine

Samsung developers created the Moon recognition engine by learning various shapes of the Moon from full to crescent, based on images that people actually see with their eyes on Earth. It uses an AI deep learning model to show the presence and absence of the moon in the image and the area (square box) as a result.

Moreover, the pre-trained AI models can detect lunar areas even if other lunar images that have not been used for training are inserted. However, the Moon can’t be normally recognized if it is covered by a cloud or something else (non-lunar planets).

Brightness control process

Well, AI enhances photography of the Moon, but better results require powerful hardware part as well. As it’s difficult to detect a small Moon in regular AI photography, the Moon’s photography is possible from 25x zoom or higher.

As soon as your Galaxy phone’s camera recognizes the Moon in the high-magnification zoom, the brightness of the screen is controlled to be dark so that the Moon can be seen clearly on the camera viewfinder, alongside maintaining optimal brightness.

If you shoot the Moon in the early evening, the sky around that is not the color of the sky you see with your eyes, but it is shot as a black sky. The tech behind this function is that when the Moon is recognized, it changes the focus to infinity to keep the moon in focus.

Shake control

Starting the Galaxy S20 series, Samsung shipped the Ultra variants (S20 Ultra/S21 Ultra/S22 Ultra) with the capability of magnification up to 100x. When the user shoots the Moon with 100x zoom/magnification, it looks greatly magnified, but it is not easy to shoot because the screen shakes due to shake of hands.

For this, Samsung created a functionality called Zoom Lock that reduces shaking when the Moon is identified so it can be stably captured on your Galaxy phone’s screen without a tripod. Zoom Lock unites OIS and VDIS technology in order to maximize image stabilization to radically surpass shaking.

If you touch the screen at high magnification or shine the Moon without moving for more than 1.5 seconds to lock, the zoom map border (in the upper right of the screen) changes from white to yellow, and the Moon no longer shakes, making it easy to shoot.

Tips to take Moon shots in 100x zoom:

1. After rotating the Galaxy in landscape mode, hold the phone with both hands.
2. Check the position of the Moon through the zoom map and adjust it to the center of the screen.
3. When the zoom map border changes to yellow, press the capture button to picture the Moon.

Learning process of lunar detail improvement engine

Once the Moon is visible at the proper brightness, your Galaxy Camera completes a bright and clear moon picture through several steps when you press the capture button. At first, the application double-checks whether the Moon detail improvement engine is required or not.

Second, the camera captures multiple photos and synthesizes them into a single shot that is bright and noise-reduced via Multi-frame Processing. Due to the long distance and lack of light in the environment, it was not enough to give the best image even after compositing multiple shots.

To overcome this, the Galaxy Camera uses a deep learning-based AI detail enhancement engine (Detail Enhancement technology) at the final stage to effectively remove noise and maximize the details of the Moon to complete a bright and clear picture.

Moon filming process

Samsung’s stock Camera application utilizes various AI technologies, which are detailed above, to provide clear Moon photos through various processes. Once focussed, AI automatically realizes the scene being shot and uses scene optimization technology to adjust settings for Moon quality.

To make Moon photography stable and easier, the Zoom Lock function, an image stabilization function, is used to provide clear moon photos on the preview screen. Once the Moon is positioned within the screen in the desired composition, press the shooting button to start shooting.

At this time, the Galaxy Camera combines multiple photos into a single photo to remove noise. As result, a bright and clear moon picture is completed by applying detail improvement technology that brings out the details of the moon pattern.

Update – March 12.

Samsung itself revealed that multiple processing techniques work before the Galaxy phone produces a crispy image of the Moon. Meanwhile, there’s a thread posted on Reddit that makes the shooting technology controversial, which shouldn’t be there.

According to the leak, Samsung Galaxy Z Fold5 will continue to use the same camera module (primary) as the Galaxy Z Fold4. In addition, the source noted that the HP2 camera installation in the next Fold is impossible, suggesting the sensor’s exclusivity to S23 Ultra throughout the year.

The sketchy leak just tells us the Galaxy Z Fold5 could be equal to its sequel in the camera department. However, it’s also reported that the primary camera sensor will remain the same. And the company might bring new Telephoto and ultrawide lenses with the Fold5.

For your info, the Galaxy Z Fold4 uses an ISOCELL GN3 sensor, featuring a 50-megapixel resolution. More key specs of this camera sensor include an f/1.8 aperture, 1.0-micron pixels, and benefits from Dual Pixel PDAF (Phase Detection Auto Focus) and OIS (Optical Image Stabilization).

Since the vanilla and Plus Galaxy S23 models don’t have upgraded primary cameras, Samsung did a pretty impressive job by enhancing the algorithm code. We hope, the same will happen with the Galaxy Z Fold5 and the company may amaze fans with software-derived tricks.

On March 16, the Korean tech giant is expected to launch the Galaxy A54 5G smartphone along with the Galaxy A34. For the next-gen foldable phones, we believe, Samsung may pick the August/September 2023 release timeline, continuing its conventional strategy.
