This invention describes a camera module for mobile phones that can switch between wide-angle and normal-angle views. It uses a main lens that can change its zoom, and a second lens positioned below it that automatically corrects for image distortions from the main lens, adjusting its correction based on the zoom level. The module also includes a controller and an image sensor, and may use an actuator to keep the lenses perfectly aligned.
Why it matters: Filed before fluid lens technology was mature enough for mass production. Advances in micro-actuators and fluid lens manufacturing since 2015 could now make this complex optical system feasible for mobile devices.
