1. A computing device, comprising: a camera comprising a lens configured to capture and provide one or more real world images; and at least one processor configured to determine whether to transform the one or more real world images to a mixed reality image; wherein when the at least one processor determines not to transform the one or more real world images, the at least one processor is configured to perform one or more auto-focusing processes of the camera to focus the one or more real world images; and wherein when the at least one processor determines to transform the one or more real world images, the at least one processor is configured to: overlay one or more computer-generated images over the one or more real world images; and override, based on determining to transform the one or more real world images, the one or more auto-focusing processes of the camera by causing the camera to focus the lens for capturing the one or more real world images based at least in part on a depth at which the at least one processor overlays at least one of the one or more computer-generated images.
