What is a megapixel? Do we need high megapixel Mobile Phones cameras?

In 2018, smartphone cameras have launched a new “digital war” of megapixels. Cameras have become one of the biggest selling points of smartphones, with an emphasis on the number of megapixels in a smartphone. Most people think that more megapixels mean better image quality. That begs the question – do we need super megapixel smartphone cameras to click better pictures and record videos?

Camera megapixels determine the quality of the camera but this is not the only factor and the truth is that more megapixels do not mean better image quality. Some of the best smartphone manufacturers in the industry still use the 12MP camera, especially Apple, which has fewer megapixels than any other smartphone camera.

What is a megapixel and how does it affect camera quality?

A megapixel (MP) is one million pixels and is a measure of the resolution of an image. The more pixels an image has, the higher the resolution and the clearer the image will be. In smartphones, cameras with a higher megapixel count can capture more detail, meaning that photos and videos taken with them will be of a higher quality. Whether or not you need a smartphone camera with a high megapixel count depends on how often you plan to use it and what you plan to use it.

Camera sensors come in different sizes. The sensor inside a smartphone is smaller than the one inside a crop sensor camera, and the crop sensor is smaller than the sensor inside a full-frame DSLR. However, they all have 12MP sensors. The size of the light spot on the sensor changes how good the image quality is. On a smartphone camera, the light spots are small, but on a full-frame camera, they’re bigger.

Megapixels are not the only factor that affects image quality. While more megapixels may mean a higher resolution, it is not the only determinant of image quality. The quality of the camera is influenced by sensor quality and lens quality, both of which are important factors. So, if you use a smartphone camera with poor sensors and lenses, you will get poor-quality images.

Do We Really Need High Megapixel Smartphone Cameras?

Great photos can be taken with a 12-megapixel camera on the back of a Google Pixel or an Apple iPhone. Just look at the photos captured by the OnePlus 10 Pro, the Samsung S22, and the Xiaomi 12 Pro to see what fantastic results these cameras can generate.

No, a high megapixel camera isn’t essential. Megapixels do have an important role but they are not the main reason why a camera quality is good or bad. Numerous factors make a camera great, and the megapixel count is just one of them. So before you look at the number of megapixels of a smartphone camera, be sure to check out other factors as well. Don’t get blinded by megapixel numbers and remember that software is also a really important part of photography.

Some of the biggest shots in the camera industry believe that a high-pixel smartphone is a waste. This has been acknowledged in the past by Michael Kashke, CEO of the famous German optical lens brand Carl Zeiss (now called Zeiss). Those familiar with the smartphone sector may be aware that Zeiss is now providing lens components/photography technology for both Nokia (HMD), Sony, and Vivo. So, strictly speaking, this gentleman is interested in smartphone photography these days – so why did he criticize the current ultra-high pixel mobile phones?

He explicitly opposes the “brainless pile of pixels” process. In his opinion, not to mention the small sensor of a smartphone, even if it is a flagship full-frame SLR since the size of the sensor is self-determined, it means increasing the number of pixels, but the photosensitive area. It should be. Less than every pixel, and this will inevitably reduce the sensitivity of the light, resulting in more noise in the image.

As a result, ordinary mobile phone (camera) users will find that too many pixels do not bring good image quality. And for those consumers with professional needs, that means more investment in equipment. A waste

Some of you want to counter this by saying, “Don’t you see that the XX brand is not customized with a special high-sensitivity CMOS? Isn’t this the XXXX brand mobile phone that Claims to use AI processing to clear the image?


For this reason, smartphones with an ultra-high pixel design, without exception, will not actually turn on the ultra-high pixel mode by default but will take pictures in the so-called “four in one” mode. Thus, it not only reduces the possibility of noise through pixel synthesis but also reduces the computational pressure of the processor, which enables it to perform real-time processing of noise reduction, HDR, beautification, etc. Is. Even on flagship mobile phones, the “performance” of taking pictures is not enough.

Are you a little disappointed To be honest, I was a little surprised when I first learned about the fact that the current flagship mobile phones are not capable of taking pictures with 40 megapixels?

Last words

So do we need high megapixel smartphone cameras? Well, the answer is no, the design of a perfect smartphone camera lies in its software, processing power, and many other factors. High megapixels allow for easy trimming without compromising resolution, capture highly detailed images, and enhance image quality and sophistication, but only if the overall equation of photography is balanced.
