What Do You Mean By 12 Mp+ 12 Mp Camera

If you are looking for a new mobile telephone it'due south probable that a good camera will rank loftier on your list of must-have features. But how practice yous know if the camera on a phone is good or just ok? The style some phones and cameras are marketed, y'all'd retrieve that the more than megapixels they take the amend the camera, but megapixels isn't the best mode to approximate a smartphone photographic camera. Megapixels can be a useful differentiator betwixt unlike models, but there are other indicators of camera quality that yous should proceed in mind when choosing your next smartphone.

You might look at the range of smartphones on offer and wonder, 'Is a 12-megapixel camera good enough? What'due south the highest megapixel photographic camera phone' or you might be wondering 'How many megapixels practice I need for a good picture'. In this article nosotros will attempt and answer those questions, too as explain why it's not how many megapixels that matters, but rather how big those pixels are.

What are megapixels?

A megapixel (MP) is equal to one million pixels (more or less, information technology'due south really 1,048,576 pixels).

The word pixel is fabricated up of the words picture and element. Each pixel captures low-cal and turns it into data. The data from the pixels is then combined to recreate the image.

You'd think that would mean the more pixels available, the more detailed the image, merely not necessarily.

The data nerveless is made upwardly of both good and bad information. The bad information is what nosotros refer to equally 'racket', that grainy, depression color, saturated advent.

A 8 megapixel camera captures 8 million pixels, and a 12 megapixel camera will capture 12 one thousand thousand pixels.

Most phone cameras today offer 12MP. In that location are a few exceptions though, as we will discuss in our highest megapixel photographic camera phone section below.

Is it better to have more than megapixels?

Do more megapixels mean better photo quality? Not necessarily. If you are comparison an 8MP camera phone with a 12MP camera phone it may well be that the pictures you'd be able to take with the 12MP model would exist meliorate, but they could too exist worse if the sensor is the aforementioned size. If both phones take an identically sized sensor then the pixels on the 12MP phone would demand to be smaller in order to fit.

The problem here is that smaller pixels are more than affected by noise. This is considering while whatever size of pixel collects the same corporeality of noise, larger pixels also collect more of the other 'good' information needed to recreate the image.

Ane indication of how unnecessary it is to pile on the megapixels, Samsung's Milky way S5 and Galaxy S6 came with 16-megapixel sensors, while the S7, S8 and S9 models all offer 12MP. The central divergence hither was pixel size. Both phones had the same size sensor to pack all those pixels onto, so each pixel on the 16MP telephone had to be smaller. The 16MP S6 had a one.12µm pixel size compared to the 12MP S7 phone'south 1.4µm.

Another reason why you lot don't necessarily want more than megapixels is the file size. The more megapixels, the larger the file size and the more space the prototype will have on your phone. If your phone has a limited storage then a smaller file size will appeal. Large images will also take longer to upload.

This latter point may be less of an effect moving forward every bit there is a new paradigm format being used that reduces file size. Apple tree has replaced the JPEG with the HEIF file format for photos and the HEVC (H.265) video format. These file types provide better, more efficient, pinch. Equally a upshot, photos and videos accept up less space.

Another reason why megapixels probably doesn't matter is your plans for the photos yous take. Will y'all be uploading them to Facebook or Twitter? Printing them out? Showing them off on your TV screen? Or plastering them on billboards around town? If you lot but intend to upload them to social networks, or share them via e-mail or messages, and so size actually isn't important (in fact information technology may be better if they are smaller every bit uploading them volition have less time).

How big can you print?

While you might take photos and never look at them once again, it's likely y'all will be sharing them on social media, displaying them on your computer screen, or maybe even streaming them to your Television set. You may also want to print them out. In that case a chip of maths will help you effigy out just how big you will be able to print without ruining the quality of your image.

To take a couple of examples:

A 12-megapixel image is 4000 pixels broad and 3000 pixels tall.
An 8-megapixel paradigm is 3456 pixels wide and 2304 pixels tall.

It's the size of the pixels that is important here. You want those pixels to exist printed as small as possible. Ideally you don't desire to be able to 'see' the pixels.

If you lot were to view the prototype on a screen, you would need to have around 144 pixels per inch (PPI) to get what Apple describes equally 'Retina' quality. The thought of Apple's Retina displays is that your heart isn't able to distinguish the individual pixels.

And then, if you wanted to view your epitome on a screen, at a 'Retina' resolution, your 8MP prototype couldn't exist shown larger than 24x16in, while a 12MP image would stretch to 27.8×20.85in. That might sound pretty big, but considering that 52in TVs are becoming more and more than commonplace, information technology's likely that you volition want to view your paradigm larger than the Retina resolution would permit.

Of course, when information technology comes to your Telly screen you lot aren't sitting right in front of information technology in quite the same way as you would with your laptop or iMac. So it'southward probable that you could get away with a lower resolution unless you take amazing eyesight.

Wondering how many megapixels exercise y'all demand for a good picture? It depends on the size of the photo.

When it comes to printing, the pixel density requirement tends to be much higher than that required for a screen, nevertheless, 150ppi would be the minimum for a photo print.

At 150ppi, yous could print an 8MP paradigm at 23in x 15.4in
At the same resolution, a 12MP image could be printed at 36.7in x 20in.

However, to get high-quality results, 300 pixels per inch would be the minimum.

At 300dpi, your 8MP image could exist printed at 11.5in x vii.7in.
At 300dpi, the 12MP image could exist printed at thirteen.3in 10 10in.

Given that typical photograph frames tend to be 8x6in or 10x8in, either of those photos would be large enough to fill that. But if you were hoping for something larger to hang over your fireplace, you may be out of luck.

If you lot have a different sized print in mind, this is how to work out how many pixels you will need:

How to work out how many pixels are needed for an eight ten 10in impress:

Multiply the width and the height past 300 to get the size in pixels. So, an 8 ten 10in print would be 2,400 ten 3,000 pixels.
Multiply the width pixels by the elevation pixels: 2,400 x 3,000 = 7,200,000 pixels.
Carve up that result past 1 1000000 to get the number of megapixels you demand = vii.2mp.

How many megapixels needed to print an A3 poster:

Using inches (because it's easier), multiply the width and the acme by 300: 11.7 x xvi.5in is 3,510 x 4,950
And then that'southward, 3,510 x 4,950 = 17,374,500.
Or 17.4MP.

How many megapixels needed to print 16x20in print:

4,800 10 6,000 = 28,800,000
28.8MP.

If yous don't demand to print images out bigger than 10x8in, and you won't be viewing them on a big screen, then you probably don't demand more than 12mp.

How many megapixels do you need for… 4k, 8K, Hard disk drive, 1080p?

When it comes to screens, here are some figures that might be of interest:

Total HD resolution, aka 1080p measures i,920×1,080 pixels. Then that's 1,920 x 1,080 = two,073,600 pixels (or 2MP).
4K resolution is 3,840 × 2,160 = 8.294,400 (or 8.3MP).
8K resolution is 7,680 × 4,320 = 33.177,600 (33.2MP).

And then, if you are thinking of getting an 8K Television receiver any time before long, you might want to bear that in mind.

Non that your 12MP prototype will await terrible on an 8K Tv set, it may have some loss in quality, but given that 150dpi is likely adequate resolution from a distance, it'due south unlikely that information technology will look truly dreadful (unless yous are a truly dreadful photographer).

Why you might want more than megapixels

The only reason you lot might similar a few more pixels is if you lot wanted to crop your shot. If y'all think this is a likely scenario, another thing to consider when looking for a camera phone is whether information technology has an optical zoom (as opposed, or in addition to a digital zoom), as this volition enable you to frame the shot without cropping out pixels.

An optical zoom does not lose paradigm quality because the same number of pixels are captured when the epitome is magnified. A digital zoom digitally magnifies the image. Rather than utilize the digital zoom you lot might as well use editing software to zoom in on the image afterwards, the results would probably be better.

The highest megapixel camera telephone

If despite what we take said to a higher place you are nevertheless looking for the maximum amount of megapixels, then yous need to consider an SLR camera, rather than relying on a phone.

For the maximum amount of megapixels you'd be looking at the Canon EOS 5DS or 5DS R cameras that boast a jaw-dropping 50.6MP. 2d to that is the Pentax 645Z with 51.4MP. Other meridian-of-the-range SLRs offer upwards of 36mp.

Catechism has said it's developing an SLR camera that can take 120MP shots. But information technology will exist a while before that appears on the market. And when it does, you'd need a large memory card as RAW shots are a staggering 210MB each.

Equally for the near megapixels you can go on a smartphone:

Nokia Lumia 1020 boasts 41MP (38MP).
Moto Z Force offers 21MP.
Asus ZenFone AR offers 23MP.
OnePlus 5 offers a dual-camera fix with 16MP and 20MP sensors.
Sony Xperia XZ Premium offers 19MP.
Huawei P10 offers dual cameras with 12MP and 20MP (the latter is monochrome)
iPhone Ten offers 12MP, as does the iPhone 8 and 8 Plus.

Equally we said above, 12MP is a pretty standard offering across the industry. This is probably because due to the size limit of a phone form-factor, sensors need to be tiny, and every bit a result packing on those millions of pixels means a smaller pixel size.

How to cull a adept camera phone

If megapixels are just a myth, then what should you look for in a camera phone? Beneath we will look at some of the features we think are the most important.

Sensor size and pixel size

As nosotros mentioned above, because phones are smaller than SLR cameras they can't have large sensors, which ways that pixels have to be small. The more pixels you squeeze onto a sensor, the smaller they demand to be.

If you think of each pixel as a bucket, with the big buckets collecting more h2o. The h2o in this allegory is light (or photons). So bigger sensors are amend because they allow for bigger pixels (although y'all could just accept fewer pixels).

As Apple's Phil Schiller said in the keynote announcing the iPhone 5S dorsum in 2013: "Bigger pixels equal better picture".

By increasing sensor size and pixel size manufacturers are able to make a big difference to low light sensitivity and noise. (Apple's sensor in the iPhone 5s was 15% larger than that in the iPhone 5, hence making a big bargain well-nigh this at the time of launch).

If y'all look at the world of SLR cameras, yous may see sensors measured in width and height in millimetres, simply in the earth of contacts and smartphones, you will run into sensors measured diagonally in fractions of an inch.

You'll run into measurements like this, from smallest to largest:

one/ii.3in (6.3 x iv.7mm)
one/1.7in (7.six x 5.7mm)
1in (thirteen.2mm x 8.8mm)
Micro Four Thirds or 4/3in (17.iii ten 13mm)
APS-C (23.5mm x fifteen.6mm)
Full frame (36 x 24mm)

The sensors in the iPhone 8 and X are idea to measure 1/3in for the wide bending lens, and ane/iii.6in for the telephoto lens in the Plus and Ten models. This is the same equally the older 6s and seven models. Apple hasn't really divulged this data, although it did say that the sensor was "bigger".

Picture shows: iPhone Ten, iPhone 8 and iPhone viii Plus

For comparative purposes:

The sensor in Samsung Galaxy Note 8 and Samsung S9 sensors measure 1/3.6in
LG'southward V30 has a sensor measuring ane/3.1in
Huawei'southward P20 Pro uses a i/1.7in sensor

But, it's not just sensor size that matters, as we said above, the size of the pixel is crucial to how much skillful data can be nerveless past the camera.

Every bit for pixel size, pixels are measured in micrometres or micron (written as μm).

Every bit before, Apple hasn't actually divulged the pixel size on its iPhone X or iPhone 8, just reports suggest that the wide-angle photographic camera offers a 1.22µm pixel size (the same as the iPhone 6s), while the telephoto camera on the 10 and Plus models is 1.0µm. Even so, another reports suggest that the iPhone X and viii models have 1.4μm pixels.

For comparative purposes:

Google's Pixel 2 offers 1.4µm pixels.
The Galaxy Note viii and the Milky way S9 both offer 1.4µm pixels on the wide angle camera, and 1.0µm on the telephoto camera.

Aperture

Another camera characteristic to look out for is the aperture. The aperture is the opening through which the camera lets in light. If you are attempting to accept a photo in depression-lite you may do good from an aperture that is able to let more light in, for instance.

Aperture is represented past an f-number such as f/1.4, f/2, f/2.viii, /f4, f/five.six, f/8, f/11, f/16, f/22, or f/32. The lower the f-number, the more light the lens lets in.

The iPhone X has a ƒ/1.8 aperture on the wide-angle lens and ƒ/ii.four aperture on the telephoto.
The iPhone 8 Plus has a ƒ/one.eight aperture on the broad-angle lens and ƒ/two.8 aperture on the telephoto.
LG's V30 has an f/1.vi rating.
Samsung Galaxy S9 has a Dual Aperture that allows you to choose between f/two.4 and f/1.5.

Other features

There are many more than features of a camera telephone that can help it accomplish a better photo, from the onboard editing software, to buzzwords such as Truthful Tone Flash, Behind Illumination Sensor and Optical Prototype Stabilization. But the most important factor, when it comes to getting a good photograph is, nosotros think, the ability of the photographer. Read our tips on taking better photos here.
