# capturedImage

A pixel buffer containing the image captured by the camera.

## Declaration

```swift
var capturedImage: CVPixelBuffer { get }
```

## Mentioned in

Displaying an AR Experience with Metal

## Discussion

Discussion ARKit captures pixel buffers in a full-range planar YCbCr format (also known as YUV) format according to the ITU R. 601-4 standard. (You can verify this by checking the kCVImageBufferYCbCrMatrixKey pixel buffer attachment.) Unlike some uses of that standard, ARKit captures full-range color space values, not video-range values. To correctly render these images on a device display, you’ll need to access the luma and chroma planes of the pixel buffer and convert full-range YCbCr values to an sRGB (or ITU R. 709) format according to the ITU-T T.871 specification. The following matrix (shown in Metal shader syntax) performs this conversion when multiplied by a 4-element vector (containing Y’, Cb, Cr values and an “alpha” value of 1.0): const float4x4 ycbcrToRGBTransform = float4x4(     float4(+1.0000f, +1.0000f, +1.0000f, +0.0000f),     float4(+0.0000f, -0.3441f, +1.7720f, +0.0000f),     float4(+1.4020f, -0.7141f, +0.0000f, +0.0000f),     float4(-0.7010f, +0.5291f, -0.8860f, +1.0000f) ); For more details, see Displaying an AR Experience with Metal, or use the Metal variant of the AR app template when creating a new project in Xcode.
