For more than 100 years, camera and lens makers have been doing signal processing in the analog domain with ever more carefully and cleverly shaped glass – to bend and synchronize light rays.

Now the equivalent thing, and much more, can be done in software, rendering most of that effort moot.

Modern smartphones have the computational abilities of supercomputers, and use them to produce images that rival those from expensive, heavy, bulky cameras – using tiny cheap lenses and sensors.

See, for example:

Traditional camera and lens makers need to get on the DSP wagon or be left behind. Soon – time is running out! You don’t want to be the next Kodak.
