Abstract:
1. An image processing apparatus comprising: a scanning unit that converts a original image into image data having a first resolution; an extraction unit that extracts respective areas, each of which containing a character of a character size, from the image data scanned by the scanning unit; a storage unit that stores images of the respective areas into a table; a calculation unit that calculates a frequency of appearance of each character size extracted by said extraction unit in the image data; a sort unit that sorts the images of the respective areas based on the frequency of appearance of each character size calculated by said calculation unit so that the images are placed in order of frequency of appearance of each character size from the highest frequency to the lowest frequency; a conversion unit that converts the images of the areas containing the characters having the first resolution which have been sorted by the sort unit into images of areas having a second resolution different from the first resolution; and a display unit that displays in parallel the images of the areas that contain characters having the first resolution extracted by the extraction unit and the images of the areas that contain characters having the second resolution converted by said conversion unit, wherein character sizes of the characters extracted by said extraction unit include at least the smallest character size in the original image, and wherein said display unit displays both the images of the areas containing characters having the first resolution and the images of the areas containing characters having the second resolution in the order sorted by said sort unit.
