Abstract: This method for acquiring photographic portraits of an individual consists: in acquiring a biometric image of the face of the individual by means of at least one digital camera (22), concomitantly with this acquisition, illuminating said face of the individual with at least two separate light sources that are not centered on said face, said light sources consisting of light-emitting diodes (38) managed by a PWM system. At least two acquisitions of said face are carried out, respectively: using a standard illumination, with a view to allowing the biometric acquisition of said face by said camera (22); using a differentiated illumination, that is, whereby said at least two light sources (36, 37) generate a lighting effect on said face, also acquired by said camera. These two acquisitions are carried out non-simultaneously and randomly during a short length of time.

Abstract: An installation for the acquisition of photographic portraits formed of a booth delimiting an inner space, including: a first wall delimiting a portion of the inner space of the booth, at least a portion of the first wall being transparent; a photographic apparatus or camera arranged behind a transparent or semi-transparent portion of the first wall, said device comprising a field of view directed towards the inside of the booth and having its focal plane located inside of the booth; at least one light-emitting device arranged behind a transparent portion of the first wall, capable of illuminating the inside of the booth. It comprises an additional light-emitting device, comprising at least two light-emitting surfaces, illuminating the inside of the booth and respectively arranged on a second and a third walls facing each other and delimiting the inner space of the booth.

Abstract: This installation includes: a light source; means for storing film photoresist for exposure and exposed photoresist; a film carrier for positioning said film photoresist at an exposure plane; a projection lens capable of projecting the digital images at the exposure plane; a liquid crystal matrix where the various digital images to be exposed are displayed; a retractable mirror oriented at 45° to an optical axis of the projection lens; and an image analysis device positioned symmetrically to said exposure plane with regard to the plane containing said mirror when the latter is in place on the optical axis. When said mirror is positioned on the optical axis, the image analysis device is suitable for receiving the image transmitted by the liquid crystal matrix issuing from the projection lens. The signals thereby detected are processed using an associated software, for setting the characteristics of the optical members of the installation.
