How Many Pixels Does The Best Camera Have
Buy whatever smartphone, and 1 of the headline features will exist the megapixel count of the cameras that come on the device. Often the front "selfie" camera volition accept a lower megapixel count than the camera (or cameras) at the rear of the telephone, because yous're usually belongings the photographic camera a lot closer to your face up at the front than the subject area you're shooting at the rear.
We've reviewed and tested the market place's acme smartphones, looking at low-lite performance, front-and-rear facing cameras, picture settings, detection AI and more. The best cameras we've tested to date are on the Huawei Mate 20 Pro, the Samsung Milky way S9+ and the Apple iPhone XS Max.

To understand what a megapixel is, yous need to understand what a pixel is. A pixel is, in visual and technology terms, a unmarried dot in a visual image.
Thinking back to the bad onetime days of CRT TVs, if you stared really closely at the screen, y'all could make out the individual piddling scarlet, blue and green onscreen dots. Each of those was a pixel. Stare closely at your LCD or OLED Tv and you probably won't see the same thing, because today's TVs (and any other digital display) tend to pack in millions of pixels into the same space, leading to crisper images that appear more natural.
Each pixel'due south job in a digital camera of any type is to capture the image information of whatsoever you're pointing the camera at, relative to the reflected light from that object. A megapixel (MP) is a count of the number of pixels in an epitome, where the mega- prefix denotes a 1000000. So an 8MP smartphone photographic camera contains a sensor with 8 1000000 pixels, a 16MP camera has xvi million pixels on its sensor so on.
In that location's no absolute hard and fast answer to this question, considering it depends on how you define "need". In the context of images, the most important consideration is how and where you intend to display them.
It's feasible to print lower-megapixel photos at larger sizes, but typically a college megapixel count will let you to more comfortably print A4 or poster-sized photos simply because in that location's less "stretching" needed to expand the paradigm to the desired size.
What about if you're just ever showing your photos on a digital screen? There, you tin can use some elementary maths to determine a minimum megapixel count. A Full HD TV, for example, has a pixel count that equates to but 2MP, and then anything higher than that will be scaled down when shown on the screen. If yous're viewing images on a 4K brandish, that figure bumps upward to 8MP.
These days, the reality is that but well-nigh any phone that isn't a pure budget handset is likely to shoot at 8MP or amend, and that's non a tendency that'south going to contrary all of a sudden. If y'all never programme on press physical photos, a college megapixel count isn't going to exist quite as critical a factor, although there are other areas where it tin be surprisingly handy.
Using a higher megapixel rating to create a zoom is ane of those areas. Nosotros have seen a smattering of photographic camera/smartphone hybrids, such equally Samsung'due south Galaxy Zoom or Panasonic's Lumix CM1, but for the most role, true optical zoom in a higher place 5x isn't something you become on a smartphone. What you can do withal is the digital equivalent of zooming in past cropping a higher megapixel photo down to a lower megapixel equivalent.
That sounds confusing, and then here'due south a quick example. If you lot took a photo of a bird that was flying far abroad, you might only get one shot with a 16MP camera. That gives y'all a shot with four,920 past 3,264 pixels in it, but the bird might be the bodily point of involvement in the shot, with a lot of blue sky that you don't really want. On a traditional camera with optical zoom, you lot'd simply zoom in to brand the bird more of a focal point.
Using digital zoom, on the other paw, you might cutting down the image to say 3008 by 2000 pixels, making the bird much more than of the focus of the shot and ending up with what is finer a 6MP photo from your 16MP original. Crop in closer to, say, 2048 by 1536, and you'd have an even closer shot of the bird at 3MP resolution. It's entirely feasible that even with so much cropping, the resulting image could be reasonably pleasant, although it will manifestly not pack quite so much detail as if you lot were able to get up shut with your avian friend.
Where this becomes a bigger upshot is if y'all're using a phone with a less-powerful camera. On a 3MP camera, for example, cropping in would bring the resolution much farther down, leaving y'all with a blurry bird shot potentially acceptable as an online avatar pic only not useful for impress purposes.
The 1 notable downside to a larger megapixel photo is that you've got to store all those pixels somewhere. If you lot're ever shooting at the maximum capability of your smartphone, you'll use up a lot more space than if you shoot at lower resolutions. (If you set your telephone to automatically upload pictures to a cloud service like iCloud, Google Bulldoze or Dropbox, y'all'll besides chew through a lot of data.)
Most smartphone photographic camera apps allow you lot to prepare the megapixel count of each shot, so if you're using a phone with fixed storage, similar an iPhone of any generation or one of Google'due south Pixel phones, turning the resolution down on your shots tin be a bang-up way to save local storage space. Comport in mind with the Pixel phones that Google provides (for the time being) unlimited online storage to lessen the strain on your local storage.
What's important to realise is that when it comes to paradigm quality, it's non just a raw numbers game.
A smartphone with an eight megapixel photographic camera might actually take better pictures than ane with a 21 megapixel camera, irrespective of camera operator skill.
That's because in that location's more than to taking images in a variety of situations than just cramming a higher megapixel count into a camera.
Outset of all, there'due south the size of the individual pixels to take into consideration, especially if you're shooting in low-lite situations. Some smartphones such as Apple's iPhones take cameras with lower megapixel counts but larger individual pixel sizes inside that overall count.
That matters, because the part of each pixel is to capture the light from any you lot're pointing the camera at. A larger pixel size – measured in nanometers – allows more light to make its way to the sensor, which means information technology's more than sensitive to low-cal in most situations. The larger the pixel size, the larger the overall sensor and the better the general capabilities of the smartphone photographic camera.
Software can besides play an important function here. Many smartphones offering camera apps finely tuned to the specifics of the onboard camera optics on that phone, making them better or worse than other smartphones even with the aforementioned raw megapixel count.
And then in that location's the issue of phones with dual lenses, each with their ain optical quality. Dual lens camera phones are very large right now, merely there'south a wide array of approaches when it comes to what you lot do with that secondary lens. Nosotros're even starting to encounter more phones emerge with up to 3 lenses, providing a lot of potential photographic flexibility, although information technology's important to know the specifications and uses of those lenses considering there'due south a wide number of approaches to the multi-lens trouble.
Some phones, such as the Apple iPhone XS or Samsung Galaxy S9 Plus offer a secondary telephoto lens. Others offer wide angle lenses, such as LG's G7 ThinQ.
Some phones take experimented with lenses that only shoot in monochrome, as is the case with Huawei's P10 Plus and Mate x handsets. This is both for the effect and in society to mix colours betwixt both lenses for a more pleasing overall film.
Some dual lens cameras in the mid-range tend to have very low megapixel secondary cameras that are there purely to provide photographic "bokeh", or background focus mistiness, and on those phones you typically can't access the secondary camera every bit a separate entity. Instead, information technology'south just a depth sensor to give your portrait photos a little more refinement.
Above that, dissimilar camera apps give yous varying levels of control over your smartphone's functionality, from whether or non it'll shoot in RAW format to shutter timing and even specific modes for selfie shots to "beautify" your confront – although results at that place can vary quite widely.
Information technology'south worth pointing out that it is perfectly feasible to take very good photographs with a lower quality or smaller sensor. There are always the issues of composition skill and timing to take into account. Having more tools in your camera toolbox, fifty-fifty with a smartphone photographic camera, gives you more than possibilities, just it won't automatically make you a improve photographer.
Some smartphone cameras also characteristic optical image stabilisation. This packs tiny sensors into the camera lens to notice and correct for the infinitesimal vibrations that your hands make when taking photos. The practical effect of all that applied science should be a significant reduction in the amount of blur in your shots, although again the small scale of smartphone cameras means that they can't apply as much correction as on a "full" lens photographic camera such every bit a DSLR.
In that location really isn't a hard and fast rule that tin declare a given camera "best" for, say, Instagram, Facebook or Flickr, considering the reality of each given photograph should be judged on its ain merits.
Mobile data usage figurer
Scared of excess data charges on your mobile?
We'll estimate how much mobile data you need and how to manage your usage.
If, nevertheless, you're very serious near your smartphone photography, you're going to largely want to concentrate on the premium end of the sector, because this is where near phone manufacturers combine the majority of their smartphone camera design smarts.
Again, you can take great shots with an ordinary smartphone camera, merely the cheaper models often take very slow startup times, so you miss shots, or slow focus speeds, so you may stop upwards with blurry photos.
With so much variation in megapixel count from smartphone to smartphone, it'south piece of cake to forget where your current phone sits in the hierarchy of camera resolutions. If that's the instance, there are a few different ways to check the megapixel count on your camera depending on what information you have handy and what specific device y'all're using.
The simplest style to determine the megapixel count of your phone'south cameras is to check the manual. Most manufacturers provide technical specifications in the documentation that comes with your phone, then provided y'all've kept information technology and can ferret it out of the closet, yous should exist able to cheque the megapixel counts for all the cameras on your current handset.
Of course, there's a skillful gamble that documentation went out with the trash or into the nighttime recesses of your wardrobe shortly later on you unboxed your new telephone. Don't fret: you even so have plenty of options for getting the information yous want.
Checking megapixel count on an Android telephone
If you've got a relatively recent Android smartphone, checking the megapixel count is quite easy. Merely open the camera app, click the settings icon (the modest cog) and you should observe the megapixel information listed under the heading "Photo size". This settings page provides information specific to the camera you're currently using, so you'll have to back out and swap between the front and rear cameras from the main camera app to view the megapixel counts for both.
Older versions of Android and some specific photographic camera apps might not display the megapixel count so clearly. In this instance, you lot tin can calculate information technology yourself by taking a photo, opening your telephone's gallery and clicking the information icon (a lower-instance i). Here you should find the resolution of the photo in the form of width x length. By multiplying the two values together, you'll reach the megapixel count of your camera. For example, if the resolution of the image was 3024 10 4032, the result would exist 12192768, or 12MP.
Checking megapixel count on an Apple iPhone
Since there are far fewer iPhone models than in that location are Android smartphones, determining the megapixel count of your current handset is relatively elementary. Open the Settings app, click General so click Most. Hither you'll find your iPhone's Model number (probable in the form of A1234). Compare this number against Apple tree's list of iPhone models to determine what model of iPhone you have.
In one case yous know which iPhone y'all're rocking, employ the table below to ostend the megapixel count of your iPhone's forepart and rear cameras:
No, or at least not yet. Yous tin easily buy a smartphone for a couple of hundred bucks with a megapixel count that'southward identical to that of a loftier-end DSLR that could cost several 1000 for the camera body alone, permit alone the lenses to go with it, simply the gulf in terms of photographic possibilities is immense.
What is clear with the current ingather of smartphone cameras, peculiarly in the premium infinite, is that they're certainly skillful enough for near everyday purposes, particularly if yous're simply sharing shots online or viewing them on a smartphone screen. There's very piffling instance for most compact point and shoot digital cameras because of this fact. Where nosotros've seen the biggest leaps in contempo times has been in low-light operation on the smaller sensors on premium phones, making it easier to become pleasing shots even afterward the sun has gone down.
In the more budget-centric space, while you may run into a camera touted every bit existence anywhere from 8 to 21 megapixels in pure pixel count, it'south non the but consideration to bear in mind when assessing its overall photographic quality.
