Abstract
A dual-aperture zoom camera comprising a Wide camera with a respective Wide lens and a Tele camera with a respective Tele lens, the Wide and Tele cameras mounted directly on a single printed circuit board, wherein the Wide and Tele lenses have respective effective focal lengths EFLW and EFLT and respective total track lengths TTLW and TTLT and wherein TTLW/EFLW>1.1 and TTLT/EFLT<1.0. Optionally, the dual-aperture zoom camera may further comprise an optical OIS controller configured to provide a compensation lens movement according to a user-defined zoom factor (ZF) and a camera tilt (CT) through LMV=CT*EFLZF, where EFLZF is a zoom-factor dependent effective focal length.
Claims20
A camera system, comprising:
- a Wide camera that includes a Wide lens having an optical axis, an effective focal length EFLW and a total track length TTLW, wherein a ratio TTLW/EFLW is larger than 1.1;
- and
- a Tele camera that includes a Tele lens with a F number smaller than 3.2 wherein the Tele lens includes a plurality of lens elements with a first lens element with a positive refractive power facing an object side, and with a window positioned between the plurality of refractive lens elements and an image plane,
- wherein a height H of the camera system measured along an axis parallel to the optical axis is in the range of 4 mm to 12 mm, and
- wherein a height difference between the Tele and Wide cameras measured along the axis parallel to the optical axis is equal to or smaller than 1.65 mm.
