Image data smoothing method |
摘要 |
An image data smoothing method smooths image data representing a picture transmitted by a facsimile transmitter and received by a facsimile receiver in the normal mode in printing out the image data so that curves and oblique lines of the picture are reproduced satisfactorily. The image data smoothing method comprises steps of determining an objective changing picture element on an objective image data line, determining changing picture elements on a precedent image data line precedent to the objective image data line, and a subsequent image data line subsequent to the objective image data line, producing a correction image data line by reversing a predetermined number of picture elements on the objective image data line determined on the basis of the positional relation between the changing picture elements and continuous with the objective changing picture element, and inserting the correction image data line between the objective image data line and the subsequent image data line in printing out the image data on the successive image data lines.
