If you plan to buy a camera or even a smartphone (focusing on the camera), then the camera’s number is probably one of the important factors that you are considering. Different companies (especially in the field of smartphones) are equally relying on the same popular belief, phones or higher-megapixel cameras. But is there always a higher megapixel mean higher camera quality? Below is the review of this.
What is a megapixel?
Let’s look at mathematics a little bit. 1 megapixel is actually 1 million pixels in the image. So, if you know the length and width of the images recorded by the camera (both the camera and the camera), you can easily detect the megapixel of the camera, just multiply the length and width of the image.
For example, suppose the image length is 5616 pixels and its width is 3744 pixels. The multiplication is 21026304, which is 21 million pixels. So the camera that captures this image has a 21-megapixel lens.
Now let’s look at megapixels more accurately and scientifically. In the sensor, each digital camera has a number of photosuches (thumbnails), each corresponding to a pixel. When the light hits the photocathode, the color to be displayed in the photo is determined. So there’s a 12-megapixel camera that has 12 million photos.
The resolution of the display is different from the resolution of the image
Consider the fact that when we speak of a megapixel of an image, we will actually express its resolution. In the case of smartphones that may be a lot of mistakes, the screen resolution is confused with the resolution of the image.
Suppose you have recorded an image with a phone with a 12-megapixel camera and a 1920 x 1080 display resolution. The recorded image in reality has 2976 resolution at 3968 pixels, which is the same 12 megapixels (12 million pixels). So note that the resolution of the display does not correlate with the resolution of the image, but the higher the image resolution, the more detailed the image can see.

What you need in megapixels?
What a megapixel is right for your needs. If you want to use the image on a computer screen or to share with your friends, 1 to 3 megapixels is enough for you because the monitor of a typical computer will eventually be 2000 by 1,000 pixels (2 megapixels). It’s interesting to know that 4K monitors have only 8 megapixels.
If you are going to print the image, the story is different and you should go to higher megapixels; otherwise, the printed image will not be clear at all. For example, depending on the size of the image you want to register, you need the following megapixels:
- Display on computer monitor: 1 to 3 megapixels
- 6 x 4: 2 megapixel photo prints
- Photo printing 8 in 10: 5 megapixel
- 11-byte: 7-megapixel photo prints
Even for larger sizes, the same 7 megapixel is enough, because in normal mode bigger images are printed to be displayed in greater distances. So you can see the sharpness of the image less.
A lot of megapixels; a promotional trick
In contrast to the megapixels of cameras we see these days, these numbers are really low. So why do camera makers or smartphones use a lot of megapixels? The answer is simple, these companies must have a reason to make you happy to upgrade your device and buy a newer model. So, they often give megapixels a boost, encouraging the user to buy a new camera or a new one with a megapixel camera.
The obvious example is Apple. These days, smartphone manufacturers often maneuver on high-pixel megapixels, but Apple still employs 12-megapixel cameras on its flagship handset, and its handsets, with the exception of the best phones in the camera.
