Rewind allows the photographer to cherry-pick faces from a 5 picture burst and the selected pictures are merged into one photo that can be shared immediately. And Scalado is working on a new version that will have smile and blink detection and will even select which version of each face to use in the final photo.
One problem is that Rewind requires a powerful processor which is why it is being tested on Qualcomm's $1350 Mobile Development Platform phone that has a 1.5GHz second-generation Snapdragon processor. And don't expect to find Rewind as an app in the Android Market-right now Scalado is planning on having the technology only made available to OEMs for inclusion in smartphones. No word on when we might see a new handset with Rewind aboard.
