ABSTRACT:
A method and an apparatus to correct the length of an image in a flatten scanner. The method includes moving an image sensor by driving a motor; calculating a first number of pixels; calculating a difference between the first number of pixels and a second number of pixels; and correcting the length of the image scanned in the flatten scanner by using the calculated difference. Therefore, the method makes it possible that a scanned image can have the same length as that of an original image by using the difference between the first and second numbers of pixels. In addition, when a flatten scanner is developed, necessity for fine adjustment to correct the length of a scanned image is eliminated, and, therefore, time required to develop a scanner is shortened.
