<P>PROBLEM TO BE SOLVED: To improve image quality by suitably performing image processing on image data of content in which images and characters coexist in a mixed manner. <P>SOLUTION: On the basis of input image data, an image processing device acquires band information of each of a plurality of blocks into which a screen is divided. On the basis of band information of each block, the device classifies the screen into a plurality of types of areas such as an image area, a character area, and a mixed area of images and characters. The device calculates processing strength for each classified screen area. Then, the device performs predetermined image processing, such as sharpness processing, on the input image data for each classified screen area at the calculated processing strength. Thus, it is possible to prevent degradation of image quality because image processing has been performed on the image area and the character area at the same processing strength. <P>COPYRIGHT: (C)2013,JPO&INPIT |
