Abstract:
1. An image processing method for printing an image onto a print medium using a print head, in which a plurality of print elements are arranged along a first direction, while conveying the print medium in a second direction crossing the first direction relative to the print head, the image processing method comprising: an obtaining step of obtaining read data by reading a test pattern printed on the print medium using a reading unit; a detecting step of, (i) in a first case where the test pattern is printed onto the print medium without a margin at side edges of the print medium in the first direction, detecting positions in the read data respectively corresponding to the side edges of the print medium in the first direction, and (ii) in a second case where the test pattern is printed onto the print medium with a margin at the side edges of the print medium in the first direction, detecting positions in the read data respectively corresponding to side edges of the test pattern in the first direction; and a setting step of setting an analytical range of the read data to (i) a range between the detected positions respectively corresponding to the side edges of the print medium in the first case and (ii) a range between the detected positions respectively corresponding to the side edges of the test pattern in the second case.
