A light-and-shade inspection apparatus and method therefor include an image pick-up device for picking up an image of an object across a dimension (e.g., width) thereof to produce an image data, a projection operational portion for calculating a projection data by adding together a predetermined number of the image data, the image data being produced at each scan of the image pick-up device at a predetermined position along the width of the object, a background lightness operational portion for calculating, based on the projection data produced by the projection operational portion, a background lightness of the object across its width, and a difference operational portion for subtracting the background lightness produced by the background lightness operational portion from the image data produced by the image pick-up device, thereby substantially eliminating variations of the background lightness across the width of the object from the image data.
