PROBLEM TO BE SOLVED: To provide an image processor that performs MTF correction. SOLUTION: The image processor includes a calculation part, memory and correction processing part. The calculation part calculates a correction value to be used in MTF correction for each of a plurality of block areas formed by dividing the image area of image data generated by a scanner into a matrix shape in a main scanning direction and a sub scanning direction, and derives the correction value of the block area of one line in the main scanning direction or the sub scanning direction on the basis of the correction value for each of the plurality of block areas. The memory stores the correction value of the block area of one line derived by the calculation part. The correction processing part uses the correction value of the block area of one line stored in the memory to correct MTF of the image data generated by the scanner. COPYRIGHT: (C)2011,JPO&INPIT |
