Image processing apparatus, image processing method, non-transitory computer-readable storage medium, and image forming apparatus

An image processing method for generating image data for recording in an image forming apparatus including an image forming unit including a plurality of nozzles configured to discharge ink, comprising:

• a converting step of converting, based on characteristic information according to a characteristic of each nozzle included in the image forming unit, image data corresponding to an input print job into image data to be used for recording by the image forming unit;
• and
• a control step of executing a plurality of correction processes selectively based on image data obtained by reading an image recorded by the image forming unit,
• wherein the plurality of correction processes include first correction processing that is performed after the recording of the image according to the print job is stopped, and second correction processing that is performed without stopping the recording of the image according to the print job.

A non-transitory computer-readable storage medium storing a program which, when read and executed by a computer, causes the computer to execute the steps of an image processing method for generating image data for recording in an image forming apparatus including an image forming unit including a plurality of nozzles configured to discharge ink, the program comprising:

• a converting step of converting, based on characteristic information according to a characteristic of each nozzle included in the image forming unit, image data corresponding to an input print job into image data to be used for recording by the image forming unit;
• and
• a control step of executing a plurality of correction processes based on image data obtained by reading an image recorded by the image forming unit,
• wherein the plurality of correction processes include first correction processing that is performed after the recording of the image according to the print job is stopped, and second correction processing that is performed without stopping the recording of the image according to the print job.
