Automatic continuous flash lighting for close range image capture

A digital image processing method, comprising:

• obtaining a video image stream from a first image capture device of an electronic device, wherein the video image stream comprises a first plurality of captured images of a scene;
• obtaining concurrently with the capture of the first plurality of images, a first stream of lux estimates for the scene in a first direction;
• obtaining concurrently with the capture of the first plurality of images, a second stream of lux estimates for the scene in a second direction, wherein the first direction and the second direction are opposite directions from one another with respect to the electronic device;
• calculating a stream of lux differential values based on a comparison of corresponding estimates from the first stream of lux estimates and the second stream of lux estimates;
• determining, based, at least in part, on the stream of lux differential values, to adjust an intensity of light emanating from a first lighting element in communication with the electronic device.

A non-transitory computer readable medium comprising computer readable instructions stored thereon, wherein the computer readable instructions are executable by one or more processors to:

• obtain a video image stream from a first image capture device of an electronic device, wherein the video image stream comprises a first plurality of captured images of a scene;
• obtain concurrently with the capture of the first plurality of images, a first stream of lux estimates for the scene;
• obtain a stream of depth estimates, wherein the stream of depth estimates represent an estimated depth of an object of interest appearing in at least one of the first plurality of captured images of the scene;
• determine, based, at least in part, on the first stream of lux estimates and the stream of depth estimates, to adjust an intensity of light emanating from a first lighting element of the electronic device.
