Title:
An image processing device, a method, a program, and an image forming device
Document Type and Number:
Japanese Patent JP5916642
Kind Code:
B2
Abstract:
An image processing method corrects the image concentration of pixel rows adjacent to a pixel row corresponding to a masked defective recording element. Different quantization methods are performed for a first image region including the pixel row corresponding to the masked defective recording element and the pixel rows adjacent to the pixel row and a second image region other than the first image region. For at least some gradations, a first quantization pattern which is obtained by the first quantization method applied to the first image region has a pattern characteristic in which a spatial frequency component in a first direction parallel to the moving direction of a recording medium relative to the recording head is suppressed with respect to all spatial frequency components in a second direction perpendicular to the first direction, as compared to a second quantization pattern applied to the second image region.
