Methods and apparatus to capture images
First Claim
Patent Images
1. An apparatus, comprising:
- a resolution determiner to process a first frame of image data to determine whether a second frame of image data to be captured subsequent to the first frame is to undergo a facial recognition analysis, the resolution determiner to determine (1) whether a head is present in the first frame and (2) an orientation of the head; and
a controller to;
when the head is present in the first frame and the orientation of the head enables successful performance of the facial recognition analysis, cause an illuminator to emit light when capturing the second frame; and
when the head is present in the first frame and the orientation of the head does not enable successful performance of the facial recognition analysis, prevent the illuminator from emitting light when capturing the second frame.

Abstract
Methods and apparatus to capture images are disclosed. An example apparatus includes a resolution determiner to determine that a first frame of image data is to undergo processing at a first resolution and that a second frame of image data is to undergo processing at a second resolution lower than the first resolution; and a controller to activate an illuminator when an image sensor is to capture the first frame and to deactivate the illuminator when the image sensor is to capture the second frame.

6. A method, comprising:
-
in response to determining that a first frame of image data includes a head having a first orientation associated with successful performance of a facial recognition process, activating an illuminator while capturing a second frame subsequent to the first frame; in response to determining that the head detected in the first frame of image data has a second orientation associated with unsuccessful performance of the facial recognition process, not activating the illuminator while capturing the second frame; and performing the facial recognition process on the second frame to identify a person in the corresponding image data when the second frame is captured with the illuminator activated. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13)

14. A method, comprising:
-
in response to determining, before a first frame of image data is captured by an image sensor, that the first frame of image data is to undergo a facial recognition process based on a first orientation of a first head relative to the image sensor, using an illuminator to illuminate an area when capturing the first frame; and in response to determining, before a second frame of image data different than the first frame of image data is captured by the image sensor, that the second frame is not to undergo the facial recognition process based on a second orientation of the first head relative to the image sensor, preventing the illuminator from illuminating the area when capturing the second frame of image data, wherein the first orientation indicates a higher likelihood of successful performance of the facial recognition process than the second orientation. - View Dependent Claims (15, 16, 17, 18)

19. A tangible computer readable medium comprising instructions that, when executed, cause a machine to at least:
-
in response to determining that a first frame of image data includes a head having an orientation associated with successful performance of a facial recognition process, activate an illuminator when capturing a second frame of image data subsequent to the first frame; in response to determining that the frame of image data does not include a head having an orientation associated with successful performance of the facial recognition process, deactivate the illuminator when capturing the second frame of image data; and perform the facial recognition process on the second frame to identify a person in the corresponding image data when the second frame is captured with illuminator activated. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26)
