An image processing device of the present invention comprises: image processing groups each of which includes modules that perform predetermined image processing on pieces of divided image data obtained by dividing input image data and each of which outputs the pieces of image data processed in the respective modules via a predetermined one of the modules; an obtaining unit to which the image processing groups are connected in parallel and which obtains the pieces of image data processed and outputted from the image processing groups; a detection unit which detects an error module not performing normal processing among the modules; and a control unit which sets a usable group that is usable for the image processing among the image processing groups based on a result detected by the detection unit and which causes the usable group to execute the image processing on the pieces of divided image data.

Image processing device, printing apparatus, image processing method with control for print medium feed executed at first time interval where error module is detected and at second time interval where error module is not detected

A first processing module receives image data transferred from a controller, and executes image processing and a second processing module receives the image data transferred from the controller via the first processing module and executes image processing on the image data. The controller determines color components, of the plurality of color components of the image data, to be processed by the first processing module and the second processing module, based on at least communication amounts produced between the first processing module and the second processing module. Processed data having undergone the image processing performed by the first processing module based on the determined color components is transferred to the controller, and processed data having undergone the image processing performed by the second processing module based on the determined color components is transferred to the controller via the first processing module.
