A camera frame. A set of lines in the corners of an image, used by a camera to frame a person being photographed.
In fanart, camera frames are usually used to indicate the person is being photographed or video recorded. If there is a red ' ●REC ' or similar icon in the corner, add the recording tag too.
Camera frames are usually used by older cameras and camcorders, that had a separate physical viewfinder for the eye. They're less common in modern smartphones.
