More Information
Summary:An ink jet printing apparatus and an image processing apparatus capable of stably outputting an image with no joint streak by making the density uniform in the entire range in which the joint streak appears are provided. Consequently, the number of dots that are printed is adjusted for image data corresponding to the boundary part between printing scans performed twice and the vicinity thereof. At this time, a ration in which the number of dots that are printed in increased or decreased from a default value based the image data is changed stepwise toward a direction in which the distance from the boundary part increases. Due to this, adjustment of an appropriate number of dots in accordance with each position within the range in which the joint streak appears is performed, and therefore, it is possible to make the joint streak no longer conspicuous.
