Image processing apparatus

An image processing apparatus for processing image data by a plurality of pipeline-connected processing modules, comprising:

• a first plurality of pipeline-connected processing modules including a processing module which processes image data for every first size;
• a second plurality of pipeline-connected processing modules including a processing module which processes image data for every second size different from the first size, wherein the second plurality of pipeline-connected processing module are merged with the first plurality of pipeline-connected processing modules;
• and
• a change unit arranged at an end of the second plurality of pipeline-connected processing modules and constructed to change partial image data of the second size into partial image data of the first size.

A method of processing image data by a plurality of pipeline-connected processing modules,

• the plurality of pipeline-connected processing modules comprising:
• a first plurality of pipeline-connected processing modules including a processing module which processes image data for every first size;
• and
• a second plurality of pipeline-connected processing modules including a processing module which processes image data for every second size different from the first size, wherein the second plurality of pipeline-connected processing modules are branched from the first plurality of pipeline-connected processing modules,
• the method comprising:
• at a start of the second plurality of pipeline-connected processing modules, acquiring partial image data of the first size from the first plurality of pipeline-connected processing modules;
• and
• changing the partial image data of the first size into partial image data of the second size.
