Patent ID: 8256870

Claim:
An image recording apparatus, comprising: a recording head having a plurality of recording elements; a conveyance device which conveys at least one of the recording head and a recording medium so as to cause relative movement between the recording head and the recording medium; a recording defect information acquisition device which acquires recording defect information indicating a recording element having a recording defect, of the plurality of recording elements; a recording defect correction device which corrects an image defect caused by the recording element having a recording defect, according to the recording defect information acquired by the recording defect information acquisition device; an image reading apparatus which reads in an image of a test chart for density measurement recorded by the recording head, the image of the test chart for density measurement having been corrected by the recording defect correction device; a recording density information acquisition device which acquires recording density information indicating recording density of the plurality of recording elements, according to the image of the test chart for density measurement read in by the image reading apparatus; a density correction information calculation device which calculates density correction information according to the recording density information acquired by the recording density information acquisition device; a density correction device which corrects density of image data according to the density correction information calculated by the density correction information calculation device; an uncorrected recording defect information acquisition device which acquires uncorrected recording defect information indicating a recording element having a new recording defect which has not been corrected by the recording defect correction device when the test chart for density measurement is output; and a recording density information amendment device which amends the density correction information according to the uncorrected recording defect information acquired by the uncorrected recording defect information acquisition device.
