One of the biggest advantages of SLR cameras (http://goo.gl/XeAhti) over camera phones is the ability to achieve shallow depth of field effects (also known as bokeh, http://goo.gl/xHR774), which makes the object of interest "pop" by bringing the foreground into focus and de-emphasizing the background.
Achieving this optical effect has traditionally required a big lens and aperture, and therefore hasn’t been possible using the camera on your mobile phone or tablet. That all changes with Lens Blur, a new mode in the Google Camera app (http://goo.gl/UpMubk).
Lens Blur replaces the need for a large optical system with computer vision algorithms and optimization techniques that are run entirely on the mobile device, simulating a larger lens and aperture in order to creating a 3D model of the world.
To learn more about the algorithms and optimization that makes Lens Blur possible, head over to the Google Research Blog, linked below. We hope you have fun with your bokeh experiments!
