Proper correction data is set by scanning a test chart even if the test chart has pixel lines formed thereon as inclined with respect to a secondary scanning direction. A virtual line CL is determined in a middle position in a primary scanning direction on the test chart, which extends between center indices 43C and 44C at opposite ends in the secondary scanning direction of the test chart. A scanning lines SL extending parallel to the virtual line CL is set to each pixel line Q. Sampling areas SQ are set on the scanning line SL.
