Patent ID: 6885393

Claim:
A conveying system comprising (a) conveyor for advancing items thereon; and (b) an image-capturing apparatus for detecting individual items on the conveyor and for generating image signals representing an image of the items; the apparatus including (1) an illuminating unit formed of a matrix composed of a plurality of light-emitting diodes; (2) a picture-capturing unit for receiving light rays emitted by said matrix and modified by an item situated in a path of the light rays and for generating the image signals; and (3) a control unit connected to said matrix and said picture-capturing unit for a pulsed illumination of said matrix and for synchronizing the pulsed illumination of said matrix with actuation of said picture-capturing unit for individually capturing images of the items such that said light-emitting diode matrix only emits light during picture-capturing periods of the picture-capturing unit.
