摘要： A camera sub-assembly for a vehicular camera includes a cylindrical lens barrel and a lens holder. The cylindrical lens barrel is received in a cylindrical lens barrel receiving structure of the lens holder. An axial face of an annular flange of the cylindrical lens barrel is juxtaposed with an axial face at the outer end of the cylindrical lens barrel receiving structure of the lens holder with an adhesive disposed therebetween. An imager is disposed at a first side of an imager printed circuit board, which is attached at the lens holder. With the cylindrical lens barrel held in position relative to the imager by the adhesive, a frontmost optical element of a plurality of optical elements accommodated by the cylindrical lens barrel is distanced further from the imager than any other optical element of the plurality of optical elements. The frontmost optical element may be a glass lens element.

摘要： This application provides an optical lens, a camera module, and an electronic device. The optical lens includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens that are sequentially arranged from an object side to an image side. The first lens, the third lens, and the fifth lens all have positive focal power, the second lens and the fourth lens both have negative focal power, and the sixth lens has positive focal power or negative focal power. Object side surfaces and image side surfaces of the first lens to the sixth lens include at least one anamorphic aspherical surface. When the optical lens is applied to the camera module and the electronic device, the camera module and the electronic device can implement ultra-wide-angle photographing, and can also resolve a distortion problem in ultra-wide-angle imaging to a large degree.

摘要： During an eye-tracking operation of an optical system, one or multiple eye images are captured. One or multiple gaze points of the user are computed based on the one or multiple eye images of the user. A user interface containing one or multiple UI elements is provided based on the one or multiple gaze points of the user. A performance map of the eye-tracking operation is provided based on the one or multiple eye images of the user. At least one UI element is adjusted based on the performance map of the eye-tracking operation.

摘要： The zoom lens includes, in order from a position closest to an object side to an image side: a first lens group that has a positive refractive power; a second lens group that has a negative refractive power; an intermediate group that has a positive refractive power; and a subsequent group that has a negative refractive power. The first lens group moves during zooming. The second lens group consists of, in order from the object side to the image side, a front group of the second lens group which does not move during image blur correction and an image stabilization group which moves during image blur correction and has a negative refractive power. The zoom lens satisfies predetermined conditional expressions.
