How Samsung Galaxy Cameras Combine Super Resolution Technologies With AI Technology to Produce High-Quality Images of the Moon
Samsung is committed to delivering best-in-class camera experiences in all conditions. Since the introduction of the Galaxy S10, the Samsung Galaxy series has harnessed artificial intelligence (AI) technologies in its cameras to help users capture every epic moment anytime, anywhere.
As part of this, Samsung developed the Scene Optimizer feature, a camera functionality which uses advanced AI to recognize objects and thus deliver the best results to users. Since the introduction of the Galaxy S21 series, Scene Optimizer has been able to recognize the moon as a specific object during the photo-taking process, and applies the feature’s detail enhancement engine to the shot.
When you’re taking a photo of the moon, your Galaxy device’s1 camera system will harness this deep learning-based AI technology, as well as multi-frame processing in order to further enhance details. Read on to learn more about the multiple steps, processes and technologies that go in to delivering high-quality images of the moon.

Understanding Super Resolution and Scene Optimizer
In order to take a clear photo of the moon, Galaxy cameras harness Super Resolution to synthesize more than 10 images taken at 25x zoom or higher. The image taken at 25x zoom or above needs to eliminate noise and enhance clarity and other details.
Super Resolution technology helps produce images through multi-frame composition. When Scene Optimizer is turned on and the moon has been recognized as an object, the camera will deliver users a bright and clear image through the detail enhancement engine of Scene Optimizer on top of the Super Resolution technology.
AI Deep Learning for Moon Object Recognition
The engine for recognizing the moon was built based on a variety of moon shapes and details, from full through to crescent moons, and is based on images taken from our view from the Earth.
It uses an AI deep learning model to detect the presence of the moon and identify the area it occupies – as denoted by the square box - in the relevant image. Once the AI model has completed its learning, it can detect the area occupied by the moon even in images that were not used in training.
However, the moon will not be properly recognized by the camera and Scene Optimizer technology if it is obscured by clouds, or if the moon object itself is the side that is not visible from the Earth.
The Brightness Control Process
Once the device has recognized the moon after zooming in, it will control the brightness of the display in order to present the moon more clearly while maintaining optimal brightness.
Accordingly, when users take photos of the moon at early evening time, the sky around the moon will appear darker than the actual sky color because the device will darken the object background brightness in order to help make the moon appear more clearly. Once your device recognizes the moon, it will continuously adjust focus to stay directly on the moon.
Capturing the Most Stable Images Possible
Samsung introduced the Zoom Lock feature, which automatically reduces the effects of a shaking device without the need for a tripod. Combining OIS and VDIS technologies, Zoom Lock is able to minimize the image blur that can be caused by shaking hands and helps users take truly epic moon shots.
While zooming in and touching the display or maintaining a focus on the moon for longer than 1.5 seconds, the Zoom Lock feature will be automatically activated. The border line of the zoom map on the upper right side of the screen will change from white to yellow, and the moon will be fixed on the display.

Why not try out these tips when taking pictures of the moon at 100x zoom? ① Rotate your Galaxy device to landscape orientation and hold the phone with both hands. ② Use the zoom map to check the location of the moon and adjust the moon to be in the center of your screen. ③ When the zoom map border line changes to yellow, press the capture button to take a picture. |
AI-Based Detail Enhancement to Capture the Moon
When the moon recognized by the Galaxy device is at an appropriate brightness level, the user can press the capture button, following the camera takes several steps to deliver a bright and clear image of the moon.
First, Scene Optimizer reconfirms whether to apply the detail enhancement engine through AI processing.
Next, the camera takes multiple pictures and then synthesizes them into a single, bright image with reduced noise.
After Multi-frame Processing has taken place, Galaxy camera further harnesses Scene Optimizer’s deep-learning-based AI detail enhancement engine to effectively eliminate remaining noise and enhance the image details even further.
Samsung continues to improve Scene Optimizer to reduce any potential confusion that may occur between the act of taking a picture of the real moon and an image of the moon.
1 Scene Optimizer is available on Galaxy S series above S20 model and all Galaxy Z Fold series.
