What makes a smartphone camera really good? In your search for the smartphone with the best camera comes terms like aperture, sensor size, megapixels… In this article, we’ll unravel the megapixel mystery.
Spoiler alert! A good smartphone camera has more than just a lot of megapixels.
From the cheapest Android device to the latest iPhone; each smartphone has a camera for taking pictures and videos. We take you into the wonderful world of megapixels and other camera features that ensure sharp shots.
Understanding Camera Megapixel of Smartphones
What is a megapixel?
The term “megapixel” is a unit that indicates the number of pixels that make up a photo or video. A pixel is a tiny dot on a display or digital image. A megapixel is a bundling of one million pixels. When taking a photo, the sensor of your smartphone camera converts the light it receives into electrical signals. On the basis of these signals, the image processor determines which colour each pixel receives. This ‘collage’ of all the pixels together forms the photograph taken.
More megapixels = larger photo
A photo with a lot of megapixels has more details and is sharper than a photo with fewer megapixels. This is because more pixels get a colour. Yet more megapixels is not always better. That is because the sharpness of the vision of your eyes is comparable to a resolution of 12 megapixels. With the naked eye, you cannot see a difference between a 40-megapixel photo of the Huawei P20 Pro and a 12-megapixel photo of the Apple iPhone X.
However, those extra megapixels do come in handy during the post-processing of your photos. Because a photo with more megapixels can be cropped or zoomed in more easily without too much loss of quality. Nice for that photo wall in the living room.
Good smartphone camera: more than megapixels
The amount of megapixel is a handy first check in your search for a good smartphone camera. Yet it does not say anything about the quality of the camera. Parts such as the camera sensor and the aperture are also important for making a beautiful photo.
Camera sensor: epicentre of your smartphone camera
The camera sensor is the spider in the web of your smartphone camera. It captures the light it sees through the lens in light-sensitive cells and converts this image into electrical signals. A large sensor captures more light than a smaller sensor. A large sensor also has less noise and it better captures colour contrast.
A photo taken with a larger sensor is more like the image you see with your own eyes. An example is when you take a picture of the beach. A photo with a smaller sensor has more noise and therefore the details in the sand are less visible.
Aperture: whether or not a beautiful sunset photo?
For the evening photographers among us, the aperture is important. This is the opening between the lens and shutter. The aperture determines how much light falls on the sensor. At dusk, photos are grainy and blurry due to lack of light. So a larger opening between the lens and shutter ensures that there is still enough light on the sensor. That will be nice for a summer evening shots!
The Samsung Galaxy S9 and Galaxy Note 9 belong to the first phones with a variable aperture. With enough light, there is a small opening between the lens and shutter, a low aperture, enough to make a beautiful photo. Is the camera still in the dark? Then it switches to the high aperture and you also make a nice, sharp photo in less light.
Good smartphone camera: complex camera recipe
Megapixels say something, but really not everything about how good a smartphone camera is. One camera can have more megapixels, while the other camera can take just such beautiful photos with fewer megapixels.
Selfie camera, increasingly a megapixel caller
Since the ‘discovery’ of the selfie, the number of megapixels in the camera on the front of the phone is also becoming increasingly important. No surprise, because of a hazy selfie post on Instagram. More and more selfie cameras are real megapixel callers. For example, the selfie camera of the Huawei P20 makes snapshots in 24 megapixels. That selfie camera even has more megapixels than the 12-megapixel camera on the back of the phone. With that, your selfies will become IG ready!
