Abstract: An image forming device to scan a predetermined document includes a uniform block search unit to classify the object into a plurality of blocks and to search for uniform blocks having uniform inner pixel values, a status information detection unit to detect representative values of the inner pixel values of each of the uniform blocks searched for by the uniform block search unit and to output maximum and minimum values of the representative values, and a control unit to determine that the object is uniform if a difference between the maximum and the minimum values output from the status information detection unit is less than a predetermined threshold value. Accordingly, if the object is uniform it is possible to compensate for deterioration of screen quality by unifying the pixels of the object.
