Patent ID: 8632012

Claim:
An apparatus comprising: an illumination source for providing illumination directed toward a target object; a solid-state imager having an array of photosensitive elements for capturing an image from the target object; an imaging lens assembly comprising a base lens and a MEMS lens having a negative optical power, the imaging lens assembly being 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, wherein the base lens is configured to have an amplification factor that is at least ten times (10×) larger than the combined amplification factor due to any and all optical components in the imaging lens assembly positioned following the MEMS lens; wherein the MEMS lens comprises a MEMS actuator and a lens attached on the MEMS actuator, and the MEMS lens is configured to move the lens therein to cause a change of a distance between the lens therein and the solid-state imager when one or more control parameters are applied to the MEMS actuator; and a decoding circuitry operative to decode a barcode on the target object from the image captured by the solid-state imager.
