A front-facing camera, commonly known as a selfie camera, is a common feature of cameras, mobile phones, smartphones, tablets, laptops, and some handheld video game consoles. While stand-alone cameras face forward, away from the operator, tablets, smartphones and similar mobile devices typically have a camera facing the operator to allow taking a self-portrait photograph or video while looking at the display of the device, usually showing a live preview of the image. These are called front-facing cameras and are important for videotelephony and the taking of selfies. Often, the preview image is by default a mirror image, which is more intuitive for most people; this default can be overridden, and in any case the recorded image is not reversed.
