1. A photosensitive sensor vis-à
- -vis at least part of the radiation in the visible and/or near infrared range installed on a vehicle, wherein said photosensitive sensor is associated with an objective having a first zone that is focused to infinity so that said photosensitive sensor can capture a first image, and a second zone focused in near field so that said photosensitive sensor can capture a second image, said objective having at least one train of lenses for forming said first and second zones, and said photosensitive sensor senses said first and second images using each of said first and second zones, respectively, said objective having an exit face having a convex face having a convex shape associated with said second zone and having a surface associated with said first zone that does not comprise the same convex shape as said convex face;
said photosensitive sensor cooperating with said objective and generating a superimposed image resulting from a superimposition of said first image and said second image whereby said superimposed image comprises a sharp or focused image of both said first and second images;
said superimposed image being used to control a function on the vehicle or to operate the vehicle.
