1. A method of combined optical mark reading ("OMR") and image processing comprising:

  • providing a response sheet having thereon a grid of response positions suitable for marking and for processing by OMR and at least one response area for a response of an alphanumeric or pictorial nature at a predetermined position, said response area encompassing at least one of said positions suitable for marking and for processing by OMR, whereby a response in the response area creates in at least one response position encompassed by said response area a mark capable of detection and reading by OMR;

    scanning the response sheet by OMR to detect by OMR the presence of marks at response positions in the grid;

    sensing in said response area by OMR for marks capable of detection and reading by OMR; and

    in response to said sensing step, selectively capturing and storing in electronic memory concurrently with said OMR scanning step the image of a response of an alphanumeric or pictorial nature in said response area wherein the image is of finer resolution than the resolution of the grid response positions.
