Abstract: To provide an image processing apparatus that changes methods of storage to a memory depending on image data to be input and improves overall image processing performance, as well as a control method of the image processing apparatus. To accomplish this, the present image processing apparatus changes methods in which input image data is stored depending on whether scanner image processing is to be performed by a system control unit that comprehensively controls the image processing apparatus or performed outside of the system control unit. Specifically, when performing scanner image processing in the system control unit, since input image data is to be input directly from a CCD, the image data is stored frame-sequentially in a memory. On the other hand, when performing scanner image processing outside of the system control unit, input image data is stored dot-sequentially in a memory.
