Abstract
An information processing apparatus and an image processing method are provided. The image processing apparatus detects character data from image data, executes edge enhancement processing, using a first filter, on an edge portion of a region, out of the detected character data, that includes a region whose frequency of points or lines is greater than a predetermined frequency, and executes edge enhancement processing, using a second filter, on an edge portion of a region, out of the detected character data, that does not include a region of a spatial frequency higher than the predetermined frequency. The first filter has, in comparison to the second filter, a larger degree for edge enhancement with respect to a region having a frequency higher than the predetermined frequency.
