Systems and methods to reduce actuator power leakage
One innovation includes an imaging device having an image sensor, a lens having a movable optical element, and an actuator operative to move the one optical element to a plurality of lens positions. The imaging device further includes an electronic display, a power source electrically coupled to the...

| description | One innovation includes an imaging device having an image sensor, a lens having a movable optical element, and an actuator operative to move the one optical element to a plurality of lens positions. The imaging device further includes an electronic display, a power source electrically coupled to the camera system and to the display, the power source (e.g., voltage regulator) configured to provide power to the display and the camera system, a memory circuit configured to store information representing an actuator control value that corresponds to a low-power focus position, and an electronic hardware processor coupled to the memory circuit, the actuator and the electronic display. The processor may retrieve the actuator control value from the memory circuit and controls the actuator to move the optical element to the lens position that corresponds to the low-power focus position when the camera system is in a deactivated state. |
