Abstract:
1. An inkjet recording apparatus configured to record an image on a recording medium by ejecting ink while relatively scanning a recording head with respect to the recording medium in a direction intersecting a predetermined direction, the recording head having a plurality of ejecting ports for ejecting ink arranged in the predetermined direction, the apparatus comprising: a first correction-test-pattern recording unit configured to record a first correction test pattern using a first ejecting port group of ejecting ports continuously aligned from a first edge of the recording head, the number of ejecting ports in the first ejecting port group being smaller than the number of the ejecting ports of the recording head; a second correction-test-pattern recording unit configured to record a second correction test pattern using a second ejecting port group of ejecting ports continuously aligned in the predetermined direction, part of the ejecting ports in the second ejecting port group being selected from the ejecting ports in the first ejecting port group and from ejecting ports not included in the first ejecting port group; and a correction-data generating unit configured to generate correction data for correcting the image data corresponding to ejecting ports included in the first ejecting port group and the second ejecting port group on the basis of a colorimetric result of the first correction test pattern and a colorimetric result of the second correction test pattern.
