This is of the most common misconceptions floating around today. Mobile manufacturers these days use this as a powerful tool to hoodwink you into thinking it has something to do with camera quality. An image has pixels in two directions; horizontal and vertical They use it because even a tiny linear resolution increase results in a huge total pixel increase, since the total pixel count varies as the total area of the image, which varies as the square of the linear resolution.
In other words, an almost invisible 40% increase in the number of pixels in any one direction results in a doubling of the total number of pixels in the image.
This gimmick is used by salespeople and manufacturers to make you feel as if your current phone camera is inadequate and needs to be replaced even if the new cameras each year are only slightly better.
One needs about a doubling of linear resolution or film size to make an obvious improvement. This is the same as a quadrupling of megapixels.
A simple doubling of megapixels, even if all else remained the same, is very subtle.
The megapixel myth is also prevalent because men always want a single number by which something's goodness can be judged.
Unfortunately, it's all a myth because the number of megapixels (MP) a camera has has very little to do with how the image looks. Even worse, plenty of lower MP cameras can make better images than poorer cameras with more MP.
