Lens Blur in the new Google Camera app
Posted by Carlos Hernández, Software Engineer

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!

To help us grow we're looking for investors and we're running a Seedrs campaign. If you fancy investing in a great startup here's your chance!

Always good to get the dialogs to fit with the app. I think that some of the Android ones outlined here are in ASOP . So they would be easy to theme.
 
There’s some very simple but beautiful design happening that, even though it’s a temporary modal screen, is important to enhance the feeling of integration and not as though the user is ‘leaving’ the app experience with an Android Holo themed popup. Sol Calendar and Noom are two apps that do this particularly well in my opinion.

How Android transitions work

The Transitions framework got me curious about how it orchestrates layout rounds and animations between UI states. This post documents my understanding of how transitions are implemented in Android after skimming through the source code for a bit.

Enjoy!

After struggling with trying to figure out how various pieces fit together, I've done some research and put together the complete Android Activity/Fragment lifecycle chart. This has two parallel lifecycles (activities and fragments) which are organized vertically by time. Lifecycle stages will occur in the vertical order in which they're displayed, across activities and fragments. In this way, you can see how your fragments interact with your activities.

In addition to the attached image, I've also got an SVG: http://staticfree.info/~steve/complete_android_fragment_lifecycle.svg which is suitable for printing.

If this is missing lifecycle steps or is inaccurate in any way, let me know so I can update it!

Hi All,

We've just released a new version of the Triggertrap Android app. The new version is 2.0.2 with some bug fixes and performance improvements and should be available soon on the play store.

If you like the App then please do take a minute and give us a 5 star rating on the play store:

https://play.google.com/store/apps/details?id=com.triggertrap

By giving the app a good rating more people will download it and use it, which in turn allows us to spend more time and effort on improving and adding functionality. 

Thanks for you time and support and hope you enjoy using the new version.
IMPORTANT: THIS APP REQUIRES THE TRIGGERTRAP MOBILE DONGLE, WHICH IS AVAILA...
