A method of modulating a dynamic range of a plurality of picture elements each containing image information. The loading device is provided at least with feed means, disposed downstream of the store with respect to the direction of feed of the sheets, and able to feed the sheets into the operating station. The drive transistor has a control node coupled to the output node of the drive buffer, a first drive node, and a second drive node coupled to the amplifier output node. The information storage system communicates information to the communications center based upon a request for information initiated by the requester to the information inquiry device. New image data is generated by substituting the pixel value of the pixel of interest by the new pixel value.
