Windows Phone 8 bringing Lenses feature to expand camera functionality

WP Central

As we parse our way through the new Windows Phone 8 SDK which was leaked this morning, we’re starting to get an idea of some of the new features.

One of those is Camera Lenses, a method by which developers can add a “mini app” of sorts to within in the camera function. This will allow devs to have much more creative control over the Windows Phone camera app, allowing the creation of unique augmented reality apps and filters to really add a customized experience.

Head past the break to read the excerpts from the SDK…

WP Central

From the SDK:

  • Camera parameter configuration, such as ISO speed and exposure.
  • Real-time access to the phone’s video stream.
  • Lenses, which are special camera apps that can provide enhanced camera functionality such as effects, filters, and computational photography.
  • Multiframe capture for creating new types of camera experiences and imagery.

“In Windows Phone SDK 8.0 Developer Preview, you can create a lens that appears in the Windows Phone built-in camera app. A lens provides the user a consistent entry point into the viewfinder of your app. It is a type of extensibility available to apps that provide unique camera functionality via the camera APIs. As a lens, your app provides the user with a viewfinder experience and interacts with the camera directly. For example, a bar code reader lens would present a viewfinder to display the bar code that it’s going to scan.

Lenses shown in the lens picker also are listed in Marketplace in their standard app categories. Although a lens must provide a viewfinder experience when launched from the lens button, the app can provide other experiences, too. For example, you might create a productivity app that displays a panorama control when a user starts it from the App list. But when a user starts the app from the lens picker, it displays a viewfinder.

When a user taps a lens in the lens picker, the corresponding app is launched via a deep link URI. The deep link URI targets the corresponding app and includes the string ViewfinderLaunch to indicate that the app is to be launched as a lens. Apps can use the deep link URI to recognize a lens launch.

After opening a lens, the user can tap the hardware Back button to return to the built-in Camera app.”

Windows Phone 8 bringing Lenses feature to expand camera functionality

This will be much easier than the current approach. I hope it encourages Devs to include an HDR Mode. I routinely shoot hand held HDR images with my Windows phone with excellent results. The whole thing would be much easier if I could just select an HDR mode and shoot. :-)

@sHAYM4N - thanks for the suggestion. Its a good App, but I'm not looking for pseudoHDR but the real thing with a truly extended dynamic range. Given the inherent limitations on cell phone cameras, the effect is quite helpful in creating life-like images :-)

I'll have to look through the SDK in more detail, but the extended Camera APIs look promising. A camera app with more control (a la ProCamera in iOS) should now be possible.
