Abstract
A reference original having a reference image is prepared and photoelectrically read with an image reader. The image thus obtained includes a true image and a false image which is called as a ghost or a flare. The relationship between the true image and the false image is detected. Then, an objective image to be reproduced is photoelectrically read with the image reader. The image thus obtained has a true image and a false image of an objective. The false image is eliminated using the relationship detected for the reference original.
