Patent attributes
The invention aims to achieve slim design by employing a light path folding optical system, add a hand-shake correction capability, and lower power consumption. An imaging lens device includes a light path folding optical system having a reflector that folds the optical axis incident perpendicular to the gravitational direction toward the gravitational direction, and an imaging element that converts an image formed by the light path folding optical system into an electrical signal. The imaging lens device also includes drive means that moves some of lens groups or one lens (hereinafter referred to as “shake correction lens group”) in the direction perpendicular to the optical axis folded toward the gravitational direction by the reflector (hereinafter referred to as “vertical optical axis”). The shake correction lens group is moved in the direction perpendicular to the vertical optical axis to move the image in the direction perpendicular to the vertical optical axis.
