摘要： Show-through is suitably removed while an image, such as a tag or highlighter, on a first surface is prevented from being removed. A luminance value of a pixel of a target region is increased based on a first correction amount in a case where the pixel is not a pixel of a halftone dot region and a value specified based on a saturation of the pixel of the target region is less than a predetermined value, or a luminance value of the pixel is increased based on a second correction amount less than the first correction amount in a case where the pixel is not a pixel of the halftone dot region and the value specified based on the saturation of the pixel of the target region is greater than or equal to the predetermined value.

摘要： The image processing apparatus obtains a degree of variation in signal values of a plurality of pixels included in a region of a predetermined size that includes a pixel of interest of image data obtained by reading a document on which a halftone-processed image has been printed, obtains a feature amount indicating a brightness of the region. The apparatus updates a difference between the obtained feature amount and an index value corresponding to the obtained degree of variation in accordance with whether or not the difference is larger than a predetermined threshold, with respect to a plurality of index values respectively corresponding to a plurality of mutually different degrees of variation, decides a correction value of the pixel of interest using the updated difference and the index value, and corrects a value of the pixel of interest using the decided correction value.
