Megapixels and other things that affect image quality


Megapixels and other things that affect image quality

Today, many of those who buy a new smartphone are interested primarily in the number of megapixels in a smartphone camera. A good camera has become an essential factor in the choice of a particular device. However, the question is whether the number of megapixels is the only major factor in the quality of pictures taken with your favorite gadget? In other words, we want to talk today about how important megapixels are in a smartphone camera along with some other thing that we will touch upon today. After reading this article, we also recommend you go to to check Nokia phone prices as Nokia cell phones feature one of the best mobile cameras on the market.

Megapixels in a smartphone camera and their role

Pictures that any camera takes are made up of small dots, called pixels. They are arranged horizontally and vertically. The number of points placed in a single image is called megapixels. Their number is determined by multiplying the pixels arranged vertically to the pixels arranged horizontally. For example, a 3 megapixel camera has 2048 pixels horizontally and 1536 pixels vertically. If we do the math, we get 3,145,728 pixels or just 3 megapixels. Naturally, the higher the image resolution is, the more pixels will be placed horizontally and vertically, which will ultimately give us a clearer picture.

What other factors affect the quality of photos?

However, the number of megapixels in a smartphone camera is not the only factor that determines the final quality of an image. Here is what else you need to look for when considering a smartphone camera.

The size of a lens. The basic rule here is that the larger the size of the lens is, the more quality photographs you will be able to get. The larger the lens, the more light it is physically able to pass through itself thus making a picture brighter. Therefore, it is also necessary to pay attention to this factor when choosing a smartphone camera.


Zoom is the ability of a camera to draw near an image when focusing on it. There are two types of zoom: a digital one and an optical one. Most smartphones today have a digital zoom, when the camera software produces the focus with the help of a person taking a picture and a special algorithm. Optical zoom ensures autofocusing as well.

Image Stabilization. Like in case with the zoom, there are two types of image stabilization: a digital one and an optical one. To take a sharp picture without blurring with a smartphone that has a digital stabilization, you need to hold it in your hands very firmly. Whereas optical image stabilization that can be found on Nokia cell phone, for instance, uses tiny gyroscopes physically moving the camera lens to resist any sudden movement thereby making an image extremely sharp.

Summarizing, we can say with certainty that the number of megapixels in a camera of a smartphone is, of course, important, but sometimes the final image quality will also depend on other factors such as those described above. We hope the information we presented will help you make a better choice in the future.
