Abstract
The present application discloses a mobile terminal with a built-in anamorphic lens, the mobile terminal is provided with a widescreen anamorphic lens which comprises a cylindrical lens group and a spherical lens group, the cylindrical lens group at least comprises a group of cylindrical negative optical power lenses and a group of cylindrical positive optical power lenses. A widescreen anamorphic lens is arranged in the mobile terminal. The optical characteristics of the cylindrical lens in the widescreen anamorphic lens are utilized to “compress” the incident light entering horizontally while keeping the incident light entering vertically unchanged, so the widescreen anamorphic lens may compress a widescreen image into a standard image area. After the compressed picture taken by the widescreen anamorphic lens is deformed and corrected by the image correction module, widescreen images and videos may be obtained, meeting the needs of users for widescreen shooting by the mobile terminal.
