Abstract: An optical lens accessory used in conjunction with a terminal device equipped with two camera devices is provided, the optical lens accessory includes: an optical device including two fisheye lenses arranged in a back-to-back configuration, where directions of the two respective viewing angles associated with the two fisheye lenses are opposite to each other, and where viewing angle of each of the fisheye lenses is greater than 180° to allow each of the two fisheye lenses to independently frame a view in the respective direction of the respective viewing angle, to let the framed lights into the two camera devices; a housing device positioned outside the optical device, where the housing device is configured to support the optical device, and to isolate the framed lights from external stray light; and a fixture device configured to attach the optical lens accessory to the terminal device.

Abstract: An optical lens accessory for wide-angle photography is provided. The optical lens accessory includes: an optical device having a wide-angle lens. The optical device is configured to frame a view with a range of viewing angle greater than a range of viewing angle of the camera device and let framed light into the camera device; a housing device positioned outside the optical device and causing no interference to the range of viewing angle of the wide-angle lens, the housing device is configured to support the optical device, and to isolate the framed light from external stray light, thereby preventing the external stray light from interfering with an optical path of the framed light; and a fixture device configured to attach the optical lens accessory to the camera device of the terminal device while causing no interference to the range of viewing angle of the wide-angle lens.
