Samsung's design is smaller and less complex than conventional liquid lenses (shown here), which typically require an array of solid lenses to provide zoom capability
Samsung has filed a patent for a new type of liquid lens that provides not only autofocus capability, but also true optical zoom capability. Liquid lenses, with their small form factor and lack of motors or moving parts, are ideal for use in compact cameras, phones, and other mobile devices. Where a conventional liquid lens may provide only autofocus, Samsung’s design uses two separately controllable liquid lenses in a single array to provide both functions.
