|
=========================================================================== |
DESCRIPTION: |
|
SquareCam demonstrates improvements to the AVCaptureStillImageOutput class in iOS 5, highlighting the following features: |
- KVO observation of the @"capturingStillImage" property to know when to perform an animation |
- Use of setVideoScaleAndCropFactor: to achieve a "digital zoom" effect on captured images |
- Switching between front and back cameras while showing a real-time preview |
- Integrating with CoreImage's new CIFaceDetector to find faces in a real-time VideoDataOutput, as well as in a captured still image. |
Found faces are indicated with a red square. |
- Overlaid square is rotated appropriately for the 4 supported device rotations. |
