Chroma Key Demo is a Nokia Developer example demonstrating the Nokia Imaging SDK chroma key filter.

Tap on the upper original viewfinder to select a chroma key color (for example a green backdrop canvas) and use the color distance slider to adjust the threshold of the color range to be made transparent. Tap on the lower modified viewfinder to toggle between a video background and a "transparent" background.

This Nokia example application has been created to provide tips and best practice guidance for software developers and app designers, and may not have all the features you would expect in a commercial product. This application is published in Store as a free software as it may also have value to regular Nokia phone users. The source code and documentation of this example can be downloaded from Nokia Developer website.

    Simply brilliant! Recommended app for chroma keying/green screen. Is it possible for future developing and add some feature like tracking or AR? Hope so
