Declaration
var highResolutionStillImageDimensions: CMVideoDimensions { get }Discussion
Normally, the AVCaptureStillImageOutput class emits images with the same dimensions as the source AVCaptureDevice instance’s activeFormat. However, if you set highResolutionStillImageOutputEnabled to true, AVCaptureStillImageOutput emits still images with its source AVCaptureDevice instance’s activeFormat.highResolutionStillImageDimensions dimensions.
