[Continued on next page] (54) Title: CAPTURING IMAGES USED IN FACIAL RECOGNITION THROUGH EFFECTIVE USE OF EXPOSURE MAN- AGEMENT 44 Begin Receive image from camera End N = N -1 30 Configure camera z 32 Set image iteration counter to N 38 40 42 Select exposure time profile Form camera control signal W O 20 17 /096 128 Al FIG. 2 (57) : A system and method for capturing images used in a facial recognition system are provided. The system and method are configured to generate a sequential set of control signals configured to cause a camera to capture a corresponding sequential set of probe images of a face of an individual. Each control signal in the sequential set of control signals is configured to cause the cam - era to capture a probe image of the sequential set of probe images using a different exposure time. The different exposure times asso- ciated with the sequential set of control signals together foiin a predetermined profile configured to enable capture of a usable image from the sequential set of probe images despite variation in at least one of an amount of light and a skin tone of the face of the indi - vidual.
