  • Patent number: 4160596
    Abstract: A document reproduction illumination/exposure control system, for ascertang the photometric qualities of a document to be photographically reproduced and providing a responsive control signal for illumination and exposure parameters for a document reproduction apparatus, is comprised of a source of radiation for illuminating a document to be reproduced, a detector for receiving radiation incident from the document and generating a radiation-detected signal proportional thereto, storage devices for storing spectral response information regarding the image-recording medium upon which an image of the document is to be reproduced, and an illumination/exposure correction device for receiving a correctional signal representative of the correlation between the radiation-detected signal and the stored spectral response information, whereby illumination and/or exposure parameters for the reproduction apparatus may be appropriately balanced to account for variations in the spectral qualities of the document.
