Dynamics of changes in the medium resolution cameras of smartphones
The Mpix race is over. Modern flagships now compete, increasing the aperture of the cameras and adding another sensor. However, smartphones mid and budget price segments continue to increase the number of megapixels, the result is the average value increases.
Journalists Gsmarena has selected from its database for each year 100 of the most popular smartphones. Then they averaged the number of megapixels of the main camera (dual camera sensor were taken into account with a higher resolution).
As expected, increasing the average number of pixels. Growth accelerated in the period from 2011 to 2015, and then slightly slowed down. This is easily explained by the fact that to increase the resolution of smartphone cameras is possible up to a certain point, and then there comes a time when further growth of the megapixels need to increase the size of the sensor.
The larger sensor is accompanied by a thicker optical system, and the designers of smartphones on the contrary tend to decrease the thickness of devices. Recently, Samsung introduced the first sensor with a pixel size of 0.9 ám, it provides a resolution of 24 MP in a thin casing. But in the dark, to keep the noise under control, he has to resort to binning.
To provide information in a more interesting, journalists Gsmarena also highlighted among the Top 100 largest resolution, and made another curve. The graph shows the "peak PureView", which corresponds to the Nokia 808 PureView and Lumia 1020. These models have a resolution of 41 MP.
The purple curve corresponds to the average value of megapixel cameras smartphones. The pink curve shows the maximum number of megapixels in their smartphones for a given year.
On the same graph shows another interesting feature: in 2011, the maximum resolution drops to 8 megapixels. An amazing fall after two years of dominance 12 MP cameras. In 2011, there were a few models of Motorola with 13-megapixel cameras, but they were not included in these statistics because it was sold through China Telecom and were not available worldwide.
Time has proved that HTC is right that a large number of megapixels does not mean higher image quality. Today, most of the flagships use a 12 – 16mp camera. Even Sony after many years of progress 23-megapixel sensors in their smartphones XZ moved to 19 megapixels.
We do not regret that 20 megapixel cameras are gradually fading from the scene. Dual cameras seems more interesting solution in that they provide portrait mode and better quality in low light.
