Abstract:
1. An apparatus for use in decoding a bar code symbol, the apparatus comprising: a first integrated circuit chip having a wafer level camera with a sensor and a lens, at least one light source, and a plurality of contact pads disposed on a first surface of the first integrated circuit chip; a second integrated circuit chip having a processor, a memory, a plurality of contact pads disposed on a first surface of the second integrated circuit chip, and a plurality of contact pads disposed on a second surface of the second integrated circuit chip; a printed circuit board having a plurality of contact pads disposed on at least one surface of the printed circuit board; wherein the first integrated circuit chip and the second integrated circuit chip are stacked in an X-Y plane on the printed circuit board in a manner that the plurality of contact pads on the first integrated circuit chip define an interface with the plurality of contact pads on the second integrated circuit chip to allow a communication of signals between the first integrated circuit chip and the second integrated circuit chip, and the plurality of contact pads on the second integrated circuit chip define an interface with the plurality of contact pads on the printed circuit board to allow a communication of signals between the first integrated circuit chip, second integrated circuit chip, and printed circuit board; and wherein the apparatus is operative for processing of image signals generated by the wafer level camera for attempting to decode the bar code symbol.
