Abstract:
1. A recording apparatus to record an image to a recording medium, the recording apparatus comprising: a recording head having a nozzle array in which a plurality of nozzles for discharging ink is arranged in a predetermined direction; a scanning unit configured to scan the recording head to the recording medium relatively in a crossing direction which crosses the predetermined direction; a recording control unit configured to cause the recording head to record an adjusting pattern for adjusting a recording position of the recording head to the recording medium and a detecting pattern for detecting nozzle of defective discharge on a recording medium by discharging ink from a nozzle group which is formed by a part of the plurality of nozzles in the nozzle array; an obtaining unit configured to obtain an information regarding number of nozzles of defective discharge in the nozzle group based on the detecting pattern; a determining unit configured to determine an adjusting value (i) based on the adjusting pattern recorded by the recording head in a case where the number indicated by the information obtained by the obtaining unit is smaller than a threshold value, and (ii) not based on the adjusting pattern recorded by the recording head in a case where the number indicated by the information obtained by the obtaining unit is larger than the threshold value; and an adjusting unit configured to adjust the recording position of the recording head based on the adjusting value determined by the determining unit.
