Abstract

A vehicular camera has a lens assembly, a housing and an image sensor. The lens assembly has at least one adjustable lens and a lens adjustment structure. The lens assembly has an effective focal length and an optical axis associated therewith and an effective distance from the image sensor. A controller may be operatively connected to the lens adjustment structure for controlling the operation of the lens adjustment structure. The lens adjustment structure is controllable to adjust at least one of an effective focal length and an effective distance of the lens assembly to the image sensor, so as to control the distance at which an object in the field of view of the camera appears in focus on the image sensor.
