Abstract

PURPOSE:To discriminate the width and position of an original by applying shading correction by a shading correction means only on the inside part of the width of the original. CONSTITUTION:The width of the original is detected by identifying the white color of the original 21 detected by a one-dimensional image sensor 24, etc., from the black color of a roller 22 to carry the original etc., and the shading correction is applied only on the inside part (n) of the width of the original. Therefore, it is possible to prevent an image in which the black color part of the roller, etc., is read out from being corrected to the white color by the shading correction, thereby, the black color outside the width of the original can be maintained. In such a way, it is possible to identify the contour of the original, and to designate corrdinate on the original.
