There is a lot of competition among phone makers over who can release the most megapixel cameras. People now give the most important to the camera when buying a smartphone. The purpose is to frame yourself nicely, that is, to take good pictures. This is also reflected in the advertisements of smartphones.
But more megapixels means the camera is better? Or can a 100-megapixel smartphone camera take better pictures than a 10-megapixel one? Before we get to that, let’s find out what is meant by ‘megapixels’.
What are megapixels?
One million or 1 million pixels together is 1 megapixel—exactly 10 lakh 46 thousand 57 pixels. And ‘pixel’ is a combination of the words’ picture’ and ‘element.’
Each pixel captures the light coming through the camera lens, converting it into digital data. And the data obtained from the pixels is then used to create the whole picture one by one.
After reading this much, it may seem that the more pixels, the more perfect the picture. But in all cases, it may not be because the collected data can be as good as it is terrible. This incorrect data is the ‘noise’ of the film.
The 8-megapixel camera contains about 6 million pixels. Similarly, a 12-megapixel camera can hold 12 million pixels of images, and these images are 3 and 4 thousand pixels in length and width; however if the ratio of the length and width of the image is 3: 4.
Good picture in more megapixels?
In general, a picture taken with a 12-megapixel camera would be better than a picture taken with an 8-megapixel camera. However, the size of the sensor must be taken into account here. Because the sensors of the two cameras are the same size, then at 12 megapixels, a rather lousy picture will come.
The problem with increasing the number of megapixels by keeping the size of the sensor the same is that the size of each pixel becomes smaller. And if the pixels are small, there is a risk of increasing the noise.
The larger the size of the sensor, the more light can enter the camera to take pictures. And the more light, the better the view. Because this light fixes the camera’s exposure balance, dynamic range, and even sharpness; and that’s why a picture taken with a 20-megapixel DSLR camera is usually better than a picture taken with a 106-megapixel camera on a smartphone. However, it is crucial to keep the size of the smartphone small.
Another problem with smartphones with more megapixel cameras is the size of each image file. The more megapixels in the phone’s camera, the larger the image file size, the more memory will be occupied. It will also take more time to upload to Facebook or send by e-mail.
When are more megapixels better?
What you use on a smartphone is essential. Would you post a picture on social media, reminisce, or print it after seeing it on your phone or computer? How big is it to print? A4 size page or for the billboard? More megapixels can be necessary just for taking pictures for large billboards. Because when a small megapixel image is printed in large size, we say the idea is torn. Again, if you want to zoom in on a picture a lot, megapixels are essential. However, in that case, it is necessary to keep in mind the size of the sensor with the size of the pixel.
On the one hand, this writing is a bit one-sided because we’re just talking about megapixels. Because, for a good picture, there is much more critical than the aperture of the camera. All in all, just having more megapixels doesn’t mean a good camera or a good picture.
