The conversion includes determining a pixel corresponding to an abnormal nozzle based on abnormal nozzle information provided for each of droplet sizes supported by nozzles of an image forming apparatus; preventing jetting of a droplet onto the determined pixel; distributing a quantization error of the determined pixel calculated in the multilevel error diffusion process to neighboring pixels; and if extra-large droplets with a droplet size greater than the droplet size of a full-size droplet capable of filling a pixel are to be formed in the neighboring pixels as a result of distributing the quantization error, removing one or more of the extra-large droplets or reducing the droplet size of one or more of the extra-large droplets."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image processing method, image processing apparatus, image forming apparatus, image forming system, and storage medium","description":"An image processing method includes converting multilevel data of an image into a dot pattern using a multilevel error diffusion process.
