Abstract: A discharge defect of a nozzle in an apparatus that forms an image on a medium by discharging liquid from a liquid discharge head based on image data is accurately detected. A discharge defect of a nozzle is detected by comparing data (reference data) of a reference image with read data obtained by reading an output image. In this case, a mark for matching the read pixel and the nozzle position with each other is recorded on the medium, and the correspondence relationship is specified by reading the mark. In addition, data items that are converted to have the nozzle resolution by performing a filtering process corresponding to the human visual characteristics for both the data of the reference image and the data of the read image are compared with each other, thereby detecting a discharge defect of a nozzle.

Abstract: In an inkjet printer, a pattern for density correction that indicates a constant density image is printed on printing paper with a head having a plurality of outlet rows, and pattern image data that indicates the pattern is acquired. A target outlet that ejects ink toward a linear region having a missing part in the pattern is detected, and a reference outlet that is included in the same outlet row as the target outlet and located close to the target outlet is specified. A density correction value of the target outlet among density correction values that are acquired based on a density profile of the pattern is replaced with a representative value of a density correction value of the reference outlet. Through this, even if an ink ejection failure occurs in any of the outlets, appropriate density correction values can be obtained for a plurality of outlets.
