Catching Up in the Megapixel Count
The camera megapixel race is dead as most flagships have scaled back and instead chosen to race with wider apertures and secondary snappers. But mid-range and entry-level phones have been catching up in the megapixel count, pushing the average higher and higher.
We took the 100 most popular phones from our database for each year. For those we averaged the megapixels of their main camera (for dual camera phones, the higher resolution sensor was used in the calculations).
As expected, we see an upwards trend to the average pixel count. Growth accelerates from 2011 to 2015 and then it tapers off. There is not a lot to be gained by increasing the resolution after a certain point if you don’t increase the sensor size too.
A bigger sensor will require a thicker optical assembly � and phone designers are sworn enemies of thickness (for better or for worse). Samsung recently unveiled the first sensor with 0.9�m pixels, which offers 24MP resolution in a slim module. But in the dark it has to resort to pixel binning to keep noise in check.
