1. An imaging engine comprising:
a first image sensor;
a second image sensor; wherein the imaging engine is configured to:
obtain, from the first image sensor, a first image of a visual object with a background associated with a subject;
determine, in the first image, an intensity difference between a first intensity of the visual object and a second intensity of the background;
determine whether the intensity difference between the first intensity of the visual object and the second intensity of the background is equal to or greater than a threshold value;
based on the determination, send the first image to a processor to calculate a distance to the subject based on the first image;
control the second image sensor to capture a second image of the subject based on the calculated distance of the subject.
