(EN) MULTI-APERTURE CAMERAS WITH AT LEAST ONE TWO STATE ZOOM CAMERA
(FR) APPAREILS PHOTO À OUVERTURES MULTIPLES COMPRENANT AU MOINS UN APPAREIL PHOTO À ZOOM À DEUX ÉTATS
Abstract
(EN)
Multi-cameras and in particular dual-cameras comprising a Wide camera comprising a Wide lens and a Wide image sensor, the Wide lens having a Wide effective focal length EFLW and a folded Tele camera comprising a Tele lens with a first optical axis, a Tele image sensor and an OPFE, wherein the Tele lens includes, from an object side to an image side, a first lens element group G1, a second lens element group G2 and a third lens element group G3, wherein at least two of the lens element groups are movable relative to the image sensor along the first optical axis to bring the Tele lens to two zoom states, wherein an effective focal length (EFL) of the Tele lens is changed from EFLT,min in one zoom state to EFLT,max in the other zoom state, wherein EFLTmin > 1.5 x EFLW and wherein EFLTmax > 1.5 x EFLTmin,
