Patent attributes
Methods and apparatus to capture images are disclosed. An example apparatus includes an image capturing device to operate in a first illumination mode or a second illumination mode; and a logic circuit to determine whether a head detected in a first frame captured at a first time is oriented such that a facial recognition process on a second frame has greater than a threshold likelihood to succeed; place the image capturing device in the first illumination mode at the second time when the head detected in the first frame is oriented such that the facial recognition process has greater than the threshold likelihood to succeed; and place the image capturing device in the second illumination mode at the second time when the head detected in the first is not oriented such that the facial recognition process has greater than the threshold likelihood to succeed.
