Camera.setPreviewCallback
Top / Camera.setPreviewCallback
Android 2.1以前
surfaceCreated(){
camera.setPreviewCallback(cb);
camera.startPreview()
}
onPreviewFrame(byte[] data, Camera camera){
camera.setPreviewCallBack(null);
[画像処理]
camera.setPreviewCallBack(cb);
}
Android 2.2以降
- Camera.addCallbackBuffer?とCamera.setPreviewCallbackWithBufferで確保したバッファを使いまわす
surfaceCreated(){
PixelFormat pixel_info = new PixelFormat();
PixelFormat.getPixelFormatInfo(camera.getParameters()/getPreviewFormat(),pixel_info);
byte[] buffer = new byte[camera.getParameters().getPreviewSize().width * camera.getParameters().getPreviewSize().height * pixel_info.bitsPerPixel /8];
camera.addCallbackBuffer(buffer);
camera.setPreviewCallbackWithBuffer(cb);
camera.startPreview()
}
onPreviewFrame(byte[] data, Camera camera){
[画像処理]
camera.addCallbackBuffer(data);
}
