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.
Claims18
A dual-aperture zoom camera, comprising:
- a Wide camera with a respective Wide lens and a Tele camera with a respective Tele lens, 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.
A method for manufacturing a dual-aperture zoom camera comprising:
- a) providing a Wide camera having a Wide lens with an effective focal length (EFL) EFLW and a total track length (TTL) TTLW;
- b) providing a Tele camera having a Tele lens with an effective focal length EFLT and a total track length TTLT, wherein TTLW/EFLW>1.1 and wherein TTLT/EFLT<1.0;
- and
- c) configuring an optical image stabilization (OIS) controller of the dual-aperture zoom camera to compensate lens movement (LMV) of the Wide and Tele lenses according to a camera tilt (CT) input and a user-defined zoom factor (ZF);
- wherein LMV=CT*EFLZF and wherein CT is in radians and EFLZF is a zoom-factor dependent effective focal length in millimeters.
A method of compensating lens movement in a dual-aperture zoom camera comprising a Wide camera with a respective Wide lens and a Tele camera with a respective Tele lens, wherein the Wide and Tele lenses have respective effective focal lengths EFLW and EFLT and respective total track lengths TTLW and TTLT, the method comprising using an optical image stabilization (OIS) controller of the dual-aperture zoom camera for compensating lens movement (LMV) of the Wide and Tele lenses according to a camera tilt (CT) input and a user-defined zoom factor (ZF), wherein LMV=CT*EFLZF and wherein CT is in radians and EFLZF is a zoom-factor dependent effective focal length in millimeters.
