Patent Images

1. An apparatus, comprising:

  • an image capturing device to operate in at least one of a first illumination mode in which an illumination source emits light while the image capturing device is performing image data capturing or a second illumination mode in which the illumination source does not emit light while the image capturing device is performing image data capturing; and

    a logic circuit to;

    determine whether a face detected in a first frame captured at a first time by the image capturing device is in a first orientation with respect to the image capturing device, the first frame captured in the second illumination mode;

    place the image capturing device in the first illumination mode at a second time when the face detected in the first frame is in the first orientation;

    place the image capturing device in the second illumination mode at the second time when the face detected in the first frame is not in the first orientation; and

    perform a facial recognition process on image data captured under the first illumination mode, but not on image data captured under the second illumination mode.
