Biometrics imaging device and biometrics imaging method for capturing image data of a body part of a person which enable improved image data quality

A biometrics imaging device for capturing image data of a body part of a person, the biometrics imaging device comprising at least one of a visible light sensor configured for capturing image data of the body part in a visible light spectrum and a near infrared light sensor configured for capturing image data of the body part in a near infrared light spectrum, wherein:

• the biometrics imaging device includes a time-of-flight camera configured for capturing three dimensional image data of the body part of the person;
• and
• the biometrics imaging device is configured to execute an imaging procedure which includes:
• capturing three dimensional image data of a current body part posture;
• determining, based on the three dimensional image data, a difference between a desired body part posture and the current body part posture;
• providing, based on the determined difference, user guidance to a person enabling the person to adapt a body part posture in a direction of the desired body part posture;
• and
• capturing at least one of image data in the visible light spectrum and image data in the infrared light spectrum;
• and
• wherein when the determined difference is within a predefined range, the biometrics imaging device is configured to maintain a delay of less than 100 milliseconds between determining the difference and capturing at least one of image data in the visible light spectrum and image data in the infrared light spectrum.
