PURPOSE: A method and an apparatus for removing show-through in a scanned image are provided to remove show-through of an image obtained by the difference of show-through of two images obtained by a scanning sensor unit, thereby efficiently removing or reducing show-through effects of a medium in an image scanner. CONSTITUTION: A scanning unit(110) scans one or more lines of a medium(160) at luminous intensity with at least 2. A light driving unit(120) applies light to a scanning area of the medium. A scanning sensor unit(130) senses the light reflected from the medium. A controller(140) removes show-through of an image obtained by the difference between show-through of two images obtained by the scanning sensor unit.
