Abstract:
A method and apparatus for using in an imaging scanner. The apparatus includes a solid-state imager, an imaging lens assembly comprising a base lens and a MEMS lens, and an electric circuitry operative to transfer the image captured by the solid-state imager to a decoding circuitry. The imaging lens assembly is configured to focus light reflected from the target object onto the array of photosensitive elements in the solid-state imager by passing the light reflected from the target object through the base lens followed by the MEMS lens.
