An inkjet recording apparatus comprising:
- a plurality of nozzles that discharge ink droplets in accordance with image information to record an image on a recording medium;
- a detection unit that detects a defective nozzle from the plurality of nozzles;
- a non-discharge correction unit that performs non-discharge correction in which the defective nozzle detected by the detection unit is disabled from discharge and an amount of ink droplets from a nozzle that is adjacent to the defective nozzle is corrected;
- and
- a change unit that binarily changes whether or not the non-discharge correction unit performs the non-discharge correction in accordance with a tone of the image information.
An inkjet recording method comprising:
- discharging, by a plurality of nozzles, ink droplets in accordance with image information to record an image on a recording medium;
- detecting a defective nozzle from the plurality of nozzles;
- disabling the detected defective nozzle from discharge and correcting an amount of ink droplets from a nozzle that is adjacent to the nozzle disabled from discharge;
- and
- binarily changing whether or not the nozzle is disabled from discharge in accordance with a tone of the image information.
An inkjet recording apparatus comprising:
- a plurality of nozzles that discharge ink droplets in accordance with image information to record an image on a recording medium;
- detection means for detecting a defective nozzle from the plurality of nozzles;
- non-discharge correction means for performing non-discharge correction in which the defective nozzle detected by the detection means is disabled from discharge and an amount of ink droplets from a nozzle that is adjacent to the defective nozzle is corrected;
- and
- change means for binarily changing whether or not the non-discharge correction means performs the non-discharge correction in accordance with a tone of the image information.
