An image processing apparatus is provided which includes a reading unit configured to read image data of a double-page original having a binding part, an output unit configured to generate output based on the image data, and a processing unit. The processing unit is configured to identify and remove shadow data corresponding to a portion of a shadow area in the image data, determine whether two-dimensional code data is included in the image data, and control the removal of the shadow data in the image data when the two-dimensional code data is included in the image data.
