Abstract: Methods and systems to implement a miniature long range imaging engine with auto-focus, auto-zoom, and auto-illumination are disclosed herein. An example method includes detecting, by a microprocessor, a presence of an aim light pattern within the FOV; determining, by the microprocessor and in response to the detecting, a target distance of an object in the FOV based on a position of the aim light pattern in the FOV, the target distance being a distance from the imaging engine to the object; causing, by the microprocessor, a variable focus optical element to focus on the object based on the target distance; responsive to making a first determination, by the microprocessor, selecting, based on the target distance, one of a plurality of zoom operation modes; and responsive to making a second determination, by the microprocessor, selecting, based on the target distance, one of a plurality of illumination modes.
