Method for acquiring a photographic portrait of an individual and apparatus implementing this method

An installation for acquiring the photographic portrait of an individual, formed of a booth delimiting an inner space, within which said individual is to position, and comprising:

• a first wall delimiting a portion of the inner space of the booth, at least a portion of which is transparent;
• a camera arranged behind said transparent portion of said wall and comprising a field of view directed towards the inside of the booth and having its object focal plane located in the booth;
• at least two illumination light sources illuminating the inside of the booth, and arranged so that they laterally illuminate the individual's face, and being located outside of the field of view of the acquisition camera,
• wherein the illumination sources are formed of light-emitting diodes LEDs managed by a pulse width modulation (PWM) system, in that the acquisition camera is of digital type, wherein the management of the lighting of the light-emitting diodes and of the acquisition by the camera is managed by a central control unit also further ensuring the processing of the images acquired by said camera, said two illumination light sources being simultaneously activated with a view to allowing a biometric acquisition of said individual's face by said digital camera, and said two illumination light sources generating a differentiated illumination with a view of acquiring another image of said individual's face by said digital camera, said acquisitions being not carried out simultaneously but randomly carried out for a length of time shorter than 1 second.
