Moon images taken with the “Area Zoom” of Samsung’s flagship smartphone fashions seem like extra a feat of AI trickery than the rest, a Reddit person’s investigation into the characteristic claims.
Samsung’s flagship Galaxy smartphone lineup, together with the Galaxy S23 Extremely, has an extraordinarily excessive degree of zoom for the rear cameras. With a 100x zoom degree, created by augmenting 3x and 10x telephoto cameras with a digital zoom aided by Samsung’s AI Tremendous Decision expertise, it could actually seize pictures of issues very far-off.
That so-called Area Zoom might probably permit customers to {photograph} the moon, and plenty of do. Nonetheless, it could be the case that the extent of element within the moon pictures might solely be increased on account of software program shenanigans.
In Friday’s submit to the Android subreddit, “u/ibreakphotos” declared that Samsung’s Area Zoom “moon pictures are pretend,” and that that they had proof. The prolonged submit then demonstrates that perception, in a reasonably convincing method.
Referring to earlier reporting that the moon pictures from the S20 Extremely and later fashions are actual and never faked, the Redditor factors out that no-one has managed to reach proving that they’re actual or pretend, till their submit.
The person examined the impact by downloading a high-resolution picture of the moon, then downsized it to a 170 by 170-resolution picture, after which utilized a gaussian blur to obliterate any remaining particulars of its floor.
They then confirmed the low-res blurry moon at full display on their monitor, walked to the opposite finish of their room, zoomed in on the pretend celestial physique, and took {a photograph}. After some processing, a picture of the moon was produced by the smartphone, however the floor had significantly extra element for the floor than the doctored supply.

The person reckons Samsung “is leveraging an AI mannequin to place craters and different particulars on locations which had been only a blurry mess.” They go additional to emphasize that whereas tremendous decision processing makes use of a number of pictures to recuperate otherwise-lost element, this appears to be one thing completely different.
It’s proposed that it is a case “the place you’ve gotten a selected AI mannequin skilled on a set of moon pictures, with the intention to acknowledge the moon and slap on the moon texture on it.”
“This isn’t the identical type of processing that’s achieved if you’re zooming into one thing else, when these a number of exposures and completely different information from every body account to one thing,” they suggest. “That is particular to the moon.”
It’s reckoned that because the moon is tidally locked to Earth, “it is very straightforward to coach your mannequin on different moon pictures and simply slap that texture when a moon-like factor is detected,” and that the AI is “doing a lot of the work, not the optics.”
Referencing to an earlier failed try and bust Area Zoom’s high quality, Samsung assured that the characteristic used as much as 20 photos, then processed them as a composite with AI. That AI identifies the content material of the scene, after which performs a “element enhancing operate” on the topic.
On the time of a earlier investigation in 2021, makes an attempt to set off an overlay or AI processing on a clove of garlic on a black background or a desk tennis ball didn’t trick the smartphone. The 2023 take a look at utilizing a 170-by-170 decision picture of the actual moon might have given the AI processing simply sufficient fundamental element to make it suppose it was trying on the precise moon.
The brand new take a look at additionally eliminates any form of multi-frame sharpening from getting used, since it is a shot of the identical low-resolution moon for each body.
It stays to be seen if this temporary investigation will set off nearer scrutiny at the usage of AI in images, however the idea is one which has been employed throughout all the cell business. Even Apple leans on computational images to enhance the standard of pictures from its cameras.
Whereas the general public could also be satisfied that AI processing methods being utilized to photographs from smartphone cameras is an efficient factor normally, oddly particular cases akin to this may occasionally trigger some pause for individuals who care about images as an artform.
