Image processing method, image processing device, image forming device and inkjet recording device

摘要

An image processing method includes: applying mask processing to an abnormal recording element based on abnormal recording element information; converting input image data such that a pixel to be formed by the abnormal recording element is excluded; applying quantization processing that converts the converted input image data to image data having a gradation number less than a gradation number of the converted input image data; and assigning each pixel forming image data after quantization processing to a normal recording element.

1. An image processing method comprising:
an abnormal recording element information acquisition step of acquiring abnormal recording element information; a mask processing step of applying mask processing to an abnormal recording element based on the acquired abnormal recording element information; an input image data conversion step of converting input image data such that a pixel to be formed by the abnormal recording element is excluded based on the acquired abnormal recording element information; a quantization processing step of applying quantization processing that converts the converted input image data to image data having a gradation number less than a gradation number of the converted input image data; and a recording element assignment step of assigning each pixel forming image data after quantization processing to a normal recording element excluding the abnormal recording element.
