Abstract: An image pickup apparatus and a method thereof are provided. The apparatus includes a sensor array and an ADC array. The sensor array includes M×N sensor blocks SB(i,j). The sensor block includes P×Q image sensing elements Se(x,y). The ADC array is located at another side of the illuminated side of the sensor array. The ADC array includes M×N ADCs ADC(i,j). The ADC(i,j) coupled to the sensor block SB(i,j) obtains the image data Data(x,y) from the image sensing element Se(x,y) of the sensor block SB(i,j). The ADC(i,j) evaluates the gain G(x,y) based on the position of the image sensing element Se(x,y). The compensated image data Datacom(x,y) can be outputted and Datacom(x,y)=Data(x,y)×G(x,y). The image pickup apparatus could improve the optical shading problem.

Abstract: An original document of one or more pages containing human-readable printed information is encoded in one or more two-dimensional bar code symbols and transmitted by facsimile to a remote site where a facsimile of the symbols is machine read, decoded and printed to provide an accurate reproduction of the original document. The facsimile symbol can be facsimile transmitted to another remote site where the facsimile symbol is regenerated, machine read, decoded and printed as another reproduction of the original document. The machine readability of the symbol facilitates computer entry of the original document printed information. The coded symbol may also contain data used at a remote site to control processing and dissemination of the original document printed information.

Abstract: A method and apparatus is provided for controlling the function of document processing machines such as copying machines and facsimile machines. Control data is submitted to a controller in a two-dimensional symbology having error correcting capability. The control data is decoded and used to process a plurality of documents without the need of a manual keying of instructions by an operator controlling the document processing machine.
