SELF-CLEANING CAMERA LENS

摘要

A camera system includes a lens that directs light onto an image sensor, an actuator that vibrates the lens, and a charge generator that charges a surface of the lens. The camera system further includes a controller that can determine a change in transparency of the lens and selectively activate the actuator based at least in part on the change in transparency. A method includes electrically charging a surface of a camera lens, determining a change in transparency of the camera lens, comparing the change in transparency to a predetermined threshold, and selectively activating an actuator to vibrate the camera lens if the change in transparency is above a predetermined threshold.

1. A camera system comprising:
a lens configured to direct light onto an image sensor; an actuator configured to vibrate the lens; a charge generator configured to charge a surface of the lens to repel debris; and a controller configured to determine a change in transparency of the lens and selectively activate the actuator based at least in part on the change in transparency.
