<P>PROBLEM TO BE SOLVED: To provide a technique that, even if an image distortion is generated in an image acquired by reading out a test pattern by a reading device, an analysis region of the pattern for detecting an ejection state of a nozzle is accurately set to determine the ejection state of the nozzle. <P>SOLUTION: The inkjet recording apparatus includes: a control unit for recording the pattern for detecting ejection failure of each nozzle by a recording head and controlling the reading unit to read out the pattern, and a detection unit for setting the analysis region for analyzing the pattern of the readout image on the readout image for each nozzle and detecting the ejection failure, based upon a distribution state of a density in the pattern in the analysis region. In order to set the analysis region, the detection unit corrects a position of the analysis region on the readout image determined based upon an arrangement of each nozzle on a design, corresponding to the distribution state of the density in the pattern in the analysis region. <P>COPYRIGHT: (C)2012,JPO&INPIT |
