Abstract
Provided is an image processing apparatus and image processing method that are capable of outputting an image wherein seam lines caused by sudden conveyance error are difficult to notice even for a small number of multi passes printing. In order to achieve this, the number of dots that are printed in pixels is adjusted according to the density level so that the number of dots that are printed in pixels corresponding to boundary portions is larger than in pixels corresponding to areas that are not boundary portions, and so that the number of dots that are printed in pixels corresponding to boundary portions increases the higher the density level of the pixels is. As a result, it is possible to avoid the occurrence of white stripes in high-density areas without emphasizing black stripes in low-density areas.
