The camera is one of the deciding factors for consumers when switching mobile phones. This unit has evolved a lot in recent years, to the point where it allows you to record movies and take very high quality photos. Although the key is not always there megapixel (MP).

Most brands use this technical feature to promote their devices. But the fact that the camera has 12 megapixels does not make it take a photo worse than one in 200, despite the large quantitative difference.

Although we leave two sections that are much more important in the quality of the photo: sensor and Aperture opening.

What is a megapixel?

Since cell phones have cameras, MPs have been a central point of discussion to promote advancement, so it’s no surprise that consumers see that the higher the number, the better the photos they’re going to take with their phone.

A point that is more easily understood at the level marketingIn contrast to the explanation of the quality of the sensor, its series and other characteristics of the strong technical load.

Instead, megapixels are probably easier to understand because they are a unit of measurement that describes how large a photo is. This means that if a mobile phone has a 5 megapixel camera, its images will have a size of 2592×1944 pixels, which means that the maximum size in which a photo can be printed will be 32×24 centimeters.

In addition, having more megapixels also allows the photo to be cropped to a smaller size without loss of detail, whether it is for printing, cropping from mobile or simply zooming.

Quality goes beyond megapixels

As far as the cost of MP goes, their relationship is in size, but not in quality, which is determined by other factors: the sensor and the aperture of the aperture.

This part explains the reason why manufacturers have chosen to add more lenses to a mobile phone, from three to four. This is because the larger the size of the lens, the aperture, which is the opening of the lens, will be larger and allow more light to enter to capture the image. Also, this is why depth sensors, ultra-angle and others are added.

Light is a key element of an image, as it is the characteristic that allows you to capture the most colors and therefore the details of the element, which ultimately translates into better quality.

All this leads to two points. On the one hand, more megapixels don’t necessarily mean better photos, because that’s not what defines them. Admittedly, “it’s nice to say you have 100 or 200 megapixels instead of saying you have 50 megapixels, but in practice 12 megapixels is enough,” he said.

And the second point is that having more MPs can work against you because “the more megapixels in the same space, the smaller they will be and the less light they’ll catch” and “less light will cause more noise, which translates into worse image quality.” , – explains the image engineer Javier Mélenchon that Vanguard.
