Until relatively recently, several big players in the manufacture including Apple and Google used 12MP cameras in their flagship devices. In fact, their respective mid-range smartphones still use a 12MP sensor. Considering 40 megapixels has been common for years and 108MP master sensors take too entered the market, what gives? Why has it taken so long for the big guns to put more than importance on the resolution of their cameras? Information technology’s quite simple: 12MP is the ideal resolution for smartphone sensors.
There are several reasons for this, including storage space, processing time, and low lite photograph quality. Video resolution and viewing devices also play into how large a photographic camera sensor should be. So there are indirect furnishings like battery life and photographic camera app functioning.
More pixels = more data

More pixels generally hateful more data to process (at to the lowest degree for full-resolution shots), resulting in slower processing times and shorter bombardment life. This is especially true in more demanding scenarios like taking Night Mode photos or Portrait Mode shots, where in that location’s a lot more processing involved.
In fact, it’southward non uncommon to find phones with 108MP modes that don’t strip away HDR, night mode, or other advanced modes. There’s simply besides much data to procedure. To apply these features, yous often demand to step down to the default setting (more on that afterward).
Not only does a college resolution need more than processing ability then, just it also demands more storage and bandwidth. With fewer phones sporting a microSD card slot these days, cloud storage is an increasingly attractive backup method.
The issue is that if you’ve got a low data cap, you may have trouble uploading a bunch of snaps when not on Wi-Fi. Y’all besides cease up needing to pay more for cloud storage plans if you shoot a lot of video regularly.
We view photos on sub-10MP displays

Here’southward another difficult truth for megapixel obsessives: Almost users aren’t viewing the high-resolution images that we share from our phones on Ultra Hard disk displays, and even if they were, that’s only an ~8.3MP canvas.
Ultra HD is still only ~8.3MP
12MP is more than enough resolution to look well-baked on pretty much any brandish — phone displays, digital photograph frames, computers, TVs, and even projectors! In fact, to get the most out of a 12MP paradigm on an Ultra Hard disk drive brandish, you’d demand to zoom in or crop. Fun fact: many telephoto cameras from the industry’s biggest names are 12MP or beneath, anyway.
The well-nigh popular video resolution caps out at ~viii.3MP
Ultra HD 4K video has been the standard in smartphones for well over 5 years now. If you don’t take it, you likely have a low-end smartphone. Since you lot don’t even need more 10MP to exist able to shoot at 4K, 12MP is more plenty to become you going — every bit long equally your SoC and ISP tin handle shooting 4K video. This means that whether you want to shoot UHD 4K at 60fps, or 720p video at 960fps, a 10MP sensor volition do you just fine.
That said, we’ve had support for 8K video recording since the release of the Snapdragon 865 in early 2020. Still, you’ll demand a sensor with a resolution of around 33MP or higher to shoot in 8K. One valid reason to record in 8K is that you lot can treat it like a burst mode, grabbing high-quality frames from a recorded clip. Nevertheless, 8K displays aren’t affordable or ubiquitous enough to justify the pick solely for video. Infinite is also a concern with 8K, even with new codecs that shrink file sizes down.
Resolution isn’t the exist-all and terminate-all
Comparing a 12MP photographic camera from 2016 to a more modernistic photographic camera is another great way to illustrate how important other aspects of photography are. Beneath is a shot comparing the original Pixel confronting the Pixel 4. They both sport 12MP photographic camera sensors, however the Pixel 4 captures much more than color information and offers dynamic range. This is less due to newer hardware, and mostly because of a bound forward in software processing on Google’s front, with HDR+ engineering science doing the majority of the heavy lifting.
Where Google’due south Pixel phones rely on the search giant’s software to reach the best results possible, many OEMs rely on a technique chosen pixel binning. The net result of this technique is that it brings the effective pixel count downwardly by four times (or by nine times with some 108MP cameras). This means that a 40MP sensor is going to produce a 10MP paradigm. So even though your phone may have 48MP stamped on the back of it, you’re only really getting 12MP photos when y’all press the shutter button.
With pixel binning, you’re getting one-quarter final image resolution
OEMs use pixel binning techniques to increase light gathering capabilities by merging data from four smaller photosites together. When you lot want a high-resolution image, you simply switch to the native resolution mode just sacrifice low-low-cal performance and dynamic range. The effects of pixel binning — higher dynamic range, more color information, better low-calorie-free functioning — can be had with natively larger photosites seen on most 12MP cameras.
Granted, you’d lose the selection to capture more detail with a 12MP camera, but in return, you’d get a lower toll and potentially brighter images from the first. Of course, this depends on the individual manufacturer and model of the phone due to different processing techniques.
Software and processing are more important
“AI camera” is a term thrown around past a lot of companies. Whether we’re talking about software from Google, Xiaomi, Apple, Samsung, or whatever other manufacturer, image processing plays a massive office in the final image.
Prototype processing plays an important role in prototype quality, frequently more than so than hardware specs.
Beneath is an example of a photo taken with the stock photographic camera app on the OnePlus seven Pro compared with one taken on the aforementioned phone using an unofficial Google Camera app. Yous can see how unlike the colors, sharpness, and dynamic range are. Google’s version of this paradigm has then much more than dynamic range which is most evident in the left half. The colors are also far more representative of real life in the Google Camera photo. OnePlus’ version features more contrast and saturation just ultimately lacks the clarity of the Google Camera movie.

What is dynamic range in photography?
Low light and pixel size
Equally we mentioned before, 12MP cameras usually let for larger individual pixels than super high-resolution sensors. The larger the pixel size, the more than light each pixel tin can capture. A 12MP half-inch sensor would produce far cleaner low-light shots than a 48MP half-inch sensor, given that every other variable is equal. Hither’s an example of Auto Mode vs. 48MP mode on the Xiaomi Mi 9. The results are staggering! Just look at how much colour data is lost when switching to 48MP mode, and the dynamic range falls through the floor.
Pixel size, and therefore sensor size, is very important. It’southward why nosotros’ve seen phones similar the Xiaomi 12S Ultra apply huge sensors compared to Google and Apple. It makes so much difference, especially in a pocket-size form cistron such as a smartphone. Night Modes accept been introduced to try and make upwards for the lack of sensor size, by taking multiple exposures and merging them together. These have helped low lite images dramatically, only they aren’t necessarily a direct replacement for a large photographic camera sensor.
12MP is plenty, for now
Given hardware limitations such as processing power, storage infinite, and lens quality, in that location actually isn’t a need to button for higher-resolution sensors correct now. Larger sensors with larger pixels provide a much more noticeable comeback to prototype quality than pure pixel count, while a wider focus on eyes and software has already enabled growth in the smartphone camera industry.
The Pixel 6 Pro is at present my real-fourth dimension magnifier for the world
When college resolution video, more powerful processors, and faster storage are all standard, we’ll start to see the need for 40MP or above. Until then, however, a 12MP camera will do me just fine.
