How Many Megapixels Should Your Smartphone’s Camera Have?
Smartphone manufacturers are very concerned about how many megapixels a phone has. It’s one of the most talked about things in smartphone labels. You’ll see them written in big letters. They might say 12 megapixels, 48 megapixels, 50 megapixels, or even 2 megapixels. Some people find it hard to decide how many megapixels is enough. So, how many megapixels does your phone have and how many do you need? Manufacturers use megapixel counts as a clever way to market their products.

Debunking the megapixel myth
Smartphone companies’ marketing campaigns give people a very simple idea of what a megapixel is. They make it seem like megapixels are the only thing that affects the quality of your photos. For example, the Samsung Galaxy S21 and S22 Ultra have 1.08 megapixel sensors.
Samsung is very proud of its 108 megapixel sensors and how much better they make its smartphone cameras than those of its lesser pixel competitors. You might think that if your camera has more megapixels, it must be better.
But that thinking goes out the window when you look at phones like Apple’s iPhone 13 Pro Max and Google’s Pixel 5. The iPhone 13 Pro Max has a primary camera with only 12 megapixels. 12 megapixel sensors can’t compete with 108 megapixel sensors. iPhone 13 Pro Max has the best camera of any smartphone on the market. The best camera of any smartphone on the market.
It has better camera performance than the Galaxy S20 Ultra and Galaxy S21 Ultra in several areas. Similarly, the Pixel 5 Pro’s primary camera is only 16 megapixels, but that doesn’t necessarily make it worse than a device like the Samsung Galaxy A52, which has a 48-megapixel sensor.
What are megapixels?
To understand megapixels, you need to understand their smaller unit, called a pixel. Pixels are small pieces on the surface of a camera’s image sensor that pick up light. Or, you can think of them as the little building blocks used to make an image. A million of these little squares make up a million pixels. So when you say “one million pixels”, you mean “one million pixels”. Also, 12 megapixels means there are 12 million pixels.
How megapixels affect camera quality
In photography, light is very important; it is a must-have condition. Pixels are very important because they collect light on the surface of the camera’s sensor. Most of the time, the more light a pixel can capture, the bigger it is. The less light your pixel captures, the more likely your image will look better.
On the other hand, the smaller the pixel size, the less light it can capture, which can result in a less-than-great image. But it’s not all black and white. There are some shades of gray, but that’s how things work at their core. For clarity’s sake, the size of a pixel is not the same as the number of megapixels. They’re not the same thing.
The size of the little dots on the surface of your camera’s sensor is the size of the pixel. A megapixel is the number of these dots on the sensor, in millions. But what does the size of a pixel have to do with anything? How does it relate to the number of megapixels? Now, think of the two images below as your camera’s sensor, and each gray box is a pixel.
In the first image, the gray box, or pixel, is larger. Because the pixels are larger, only a few pixels can fit into the image (the camera sensor). Although the size of the second image (the size of the sensor) is the same, more pixels can fit because they are smaller.
If the size of the sensor stays the same, smaller pixels can fit, but fewer larger pixels. Keep in mind that in most cases, larger pixels are better because they can capture more light. So, when making a camera, a manufacturer may have to decide whether to make a 12-megapixel camera with 12 million large pixels or a 108-million camera sensor with 108 million small pixels.
But that doesn’t mean that fewer megapixels are always better. Yes, sometimes it does, but it depends on many things, such as the size of the sensor. Simply put, the size of the sensor is the size of the part of the camera where the small pixels are located.
The image sensor is the part of the camera that converts the light coming into the camera into an image. How you think about the number of megapixels depends on the size of the sensor. Suppose you have a 2-megapixel camera. A large sensor can easily accommodate 2 million large pixels without reducing the size.
But another 2-megapixel camera with a smaller sensor needs to use smaller pixels to hold all 2 megapixels. In short, the size of the picture sensor determines how many pixels can fit on its surface and how large those pixels can be.
If the sensor is small, it’s probably not a good idea to put more megapixels on the sensor. On the other hand, if you have a larger sensor, you can add more pixels if you want. Because of this, Samsung’s Galaxy S22 Ultra, with its 108-megapixel camera, has a very large sensor.
How many pixels should I have?
It might be easy to think that having more megapixels doesn’t change anything. Well, not all of it. When there are more megapixels, there is more room for higher resolution images. This helps when printing images or when looking at them on a large screen. In addition, higher megapixels ensure that your photos contain as much information as possible.
In addition, zoom, especially digital zoom, works best at higher megapixels. Since digital zoom is cropping, a higher megapixel camera captures enough detail to ensure that the image is not pixelated when you crop it by hand or when your camera crops it for you via digital zoom.
This can be very helpful for smartphones that use digital zoom rather than optical zoom to zoom in and out. So the more megapixels a camera has, the more detail it may be able to capture. However, it would be best if you don’t get too excited about the high pixel count. Higher megapixels don’t just mean better photos.
More megapixels is an option, if that.
It has to do with a big sensor.
Involves a great lens. It’s hard to say what a great lens is, but it’s all about the brand these days. Brands like Leica and Zeiss are known for good lenses.
There needs to be good software. Samsung, Apple and Google all have very good computational photography software. With good software, high pixel cameras can reach their full potential.
Use pixel binning. This technique digitizes the pixels and combines them with each other to make them look bigger.
