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 camera system and to the display, the power source (e.g., voltage regulator) configured to providepower 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 movethe optical element to the lens position that corresponds to the low-power focus position when the camera system is in a deactivated state. 一个创新包含一种成像装置，其具有：图像传感器；透镜，其具有可移动光学元件；以及致动器，其操作以将所述一个光学元件移动到多个透镜位置。所述成像装置进一步包含：电子显示器；电
