Apple has won their second Face ID Patent this month and this time it covers its Hybrid Mode of Illumination System

1 x cover face id

 

Last week Apple was granted a patent for Face ID relating to multi-component vision system. Today the U.S. Patent and Trademark Office officially granted Apple a second patent covering a different aspect of Face ID titled "Hybrid mode illumination for facial recognition authentication." The patent covers methods and systems for operating a facial recognition authentication process on a device. More particularly, embodiments described relate to operating a facial recognition authentication process using a combination of flood infrared illumination and patterned illumination of the user attempting to be authenticated by the facial recognition authentication process.

 

Apple's granted invention relates to a user's face being illuminated with both flood infrared illumination and patterned illumination in images captured by a device (e.g., a mobile device) to be used in a facial recognition authentication process.

 

The flood infrared illumination and patterned illumination may be provided by a single illuminator or a combination of illuminators. Both flood infrared illumination data and depth map image data may be generated from the captured images. Flood infrared illumination data may be generated by assessing areas in the images between features (e.g., speckles) in the illuminated pattern. Depth map image data may be generated by assessing the pattern illuminated on the user's face in the images. The flood infrared illumination data and the depth map image data may be generated separately from the captured images. The facial recognition authentication process may attempt to authenticate the user in the captured images as an authorized user of the device by using the flood infrared illumination data and/or the depth map image data.

 

Apple's patent FIG. 5 below depicts a representation of an embodiment of a pair of images that includes a flood IR image and a patterned illumination image; FIG. 10 depicts a flowchart of an embodiment of an empty frame verification process.
