Image processing apparatus and control method thereof, in which an address for image data depends on whether the image data is input via a detachable image processing device

An image processing apparatus that stores image data input from a reading device that reads an original document and generates image data, the image processing apparatus comprising:

• an input unit that inputs the image data from the reading device;
• a memory that stores the image data input by the input unit;
• a designator that designates an address for storing the image data into the memory, based on whether or not the image data is input via an image processing device that performs data rearrangement of the image data, wherein the image processing device is detachably connectable to the image processing apparatus;
• a controller that controls the image processing apparatus to store the image data into the memory according to the address designated by the designator;
• a same number of buffers as a number of color components of image data input by the input device for temporarily retaining the image data, wherein
• the reading device inputs in parallel, into each buffer, data of different color components, and
• the image processing device includes a division unit that divides the image data generated by the reading device into a same number of sets as the number of color components of the image data, such that when the number of color components of the image data is three, the division unit divides one line of the image data processed by the image processing device into three sets of divided data at an Mth pixel and at an Nth pixel, where M denotes a value equal to or greater than one third of the number of pixels in one line, and N denotes a value that is double the value of M, wherein the three sets of divided data all have a same data size as each other, and a padding value is added to a set of the divided data including information of the Nth and subsequent pixels among the three sets of divided data to conform to the same data size;
• and
• a transfer unit that transfers, in parallel, the sets of divided data divided by the division unit to each buffer.
