Update: Samsung’s 600MP smartphone sensor may have been confirmed (via DPReview (opens in new tab)) from a recently leaked slide that describes the concept of a 600MP sensor in a smartphone. While this doesn't necessarily mean that Samsung will definitely be producing a 600MP camera for camera phones, it's definitely interesting that Samsung is still interested in this type of huge megapixel technology.
The current size of ISOCELL pixels is 0.8um, which if used to produce a 600mp sensor, would require a huge and impractical camera bump. To make such a sensor manageable, the size of each pixel would need to be a lot smaller than what it is right now. While Samsung may not be quite ready to produce such a sensor, it’s still enjoyable to ponder the ‘what ifs’ of camera phone technology.

ORIGINAL: We've had 150MP medium format cameras, 61MP mirrorless cameras and even a 108MP Xiaomi Mi Note 10 (opens in new tab) smartphone, but now it seems like all of this megapixel mania is going to be taken to the next level – with a 600MP Samsung smartphone sensor. Did anyone ask for this technology? Not necessarily, but Samsung isn't going to let a little thing like that stop it.
Samsung is known for pushing smartphone camera technology boundaries, having pioneered the industry's first 64MP smartphone sensor and releasing a 108MP smartphone in early 2020. Admittedly, these camera phones are very impressive pieces of technology, but is a 600MP sensor really the next step?
Samsung explains (opens in new tab) that our eyes "are said to match a resolution of around 500 megapixels. Compared to most DSLR cameras (opens in new tab) today that offer 40MP resolution and flagship smartphones with 12MP, we as an industry still have a long way to go to be able to match human perception capabilities."
However, while a high megapixel count is often held up as the gold standard for image quality, it's not actually that simple. As the Samsung release itself explains: "Simply putting as many pixels as possible together into a sensor might seem like the easy fix, but this would result in a massive image sensor…"
This means that the only way to increase the amount of megapixels for a set amount of space is to make them smaller, but this results in poor image quality due to the "smaller area that each pixels receives light information from". Samsung's solution to this problem is their 'Nonacell technology', which increases the amount of light absorption that pixels are capable of.
One of the biggest arguments against high megapixel cameras is the unwieldy file sizes. If you actually had 600MP image files, they would be absolutely huge. Not only would it require a massive amount of processing power, but your phone storage would be quickly clogged up by simply taking a couple of selfies and a few snaps of your dinner.
However, while a smartphone might have a high megapixel sensor, that doesn't necessarily mean it produces high megapixel images. The Samsung Galaxy S20 Ultra employs 9-in-1 pixel binning (opens in new tab), which means that the 108MP sensor actually produces 12MP photos. If Samsung produced a 600MP sensor that employed 9-in-1 pixel binning, then this would produce 66MP photos.
This would still be a massive file size for a smartphone, but what if Samsung was able to use something like 36-in-1 pixel binning, which would reduce 600 megapixels into a 16MP image. Not only would this be a perfectly serviceable file size, but the amount of detail this would offer would be incredible. Whether or not Samsung would be able to effectively counteract the difficulties with low light this sensor would inevitably encounter is probably the biggest question mark hanging over this concept.
While a 600MP smartphone sensor might initially sound a bit ridiculous, a combination of more advanced versions of Nonacell technology and pixel binning might actually produce some genuinely fascinating imaging technology. However, we'll likely have to wait a while before we see the fruits of Samsung's labor.
