SYSTEMS, METHODS AND APPARATUS FOR CREATING AND USING GLASSES WITH ADAPTIVE LENS BASED ON DETERMINATION OF VIEWING DISTANCE AND EYE TRACKING IN LOW-POWER CONSUMPTION CONDITIONS Russian patent published in 2016 - IPC G02C7/08 G02B3/14 

FIELD: physics, optics.

SUBSTANCE: method of tracking an eye spot with low power consumption in an electrooptical apparatus, using an image sensor with active pixel sensors, includes using a processor to determine whether image sensor pixels are exposed to light with exceedance of a configured threshold value; reporting said compared image sensor pixels using an image sensor circuit; connecting a MOS transistor with threshold voltage Vth, which is connected only if the corresponding pixel is exposed to light with exceedance of the threshold value; and using a circuit with latches or registers to store connection/disconnection result or pixel state.

EFFECT: providing low power consumption.
