    Patent number: 5856877
    Abstract: Layout analysis is used in operating a digital reproduction apparatus. The device automatically segments the digital image dot data corresponding to a document image to be reproduced, to determine layout elements of the document. This is shown on a display. An operator can now select a specific layout element, such as a text column, by indicating it, and instruct the image processing unit of the apparatus to process only that element. The processing operations include color printing, gradation changing, moving and enlargement/reduction.
