The EF-45NC’s TOF sensor detects subjects from over 1.0 meter from the system; the subject’s face is immediately displayed on the 5.0 inch high resolution color display. For proper positioning, the subject will naturally center his face by simply making his or her face fit the positioning “guide box”. Vocalized instructions also command the user to move forward or back to get into range. When in the proper range, the guide box and top border turn green, indicating to the subject to stop and wait until the image capture process is completed. Like a smart phone “selfie” image, this interface is highly intuitive, with typical capture times of 0.5 seconds from proper positioning.
