Champ de vision – field of view, field of vision, visual field đź”—
Un moment il sortit de mon champ de vision, mais je le retrouvai dans la rue, posé sur le trottoir devant ma voiture.
For a moment he went out of my field of vision, but I found him again in the street, on the sidewalk in front of my car.
