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. [1] [2] [3] [4] 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.

[6] It stored up to 20 JPEG digital images, which could be sent over e-mail, or the phone could send up to two images per second over Japan's Personal Handy-phone System (PHS) wireless cellular network.

Several mobile phones with front-facing cameras were released to Western markets in 2003, including the NEC e606, [8] NEC e616, [9] Sony Ericsson Z1010 [10] and Motorola A835. [11] The front-facing camera was originally intended for video-conferencing. [12] The Motorola A920 was released in 2003 as well and may have been the first smartphone with a front-facing camera.

In May 2017, the Essential Phone introduced the notch - the removal of part of the display to accommodate the front-facing camera. The iPhone X popularized this concept after its introduction in late 2017. As of 2019, several smartphones incorporate front cameras that pop up from within the smartphone to allocate the area that would be otherwise utilized by notches to the screen. [14] [15] Under-display cameras are under development, which would place a camera under a special display that would allow the camera to see through the display. [16] [17] [18] [19]
