    • 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.
    • 提供根据要输入的图像数据将存储方法改变到存储器并提高整体图像处理性能的图像处理装置以及图像处理装置的控制方法。 为了实现这一点,本图像处理设备根据是否由综合控制图像处理设备或在系统控制单元外执行的系统控制单元执行扫描器图像处理来改变其中存储输入图像数据的方法。 具体地说,当在系统控制单元中执行扫描器图像处理时,由于直接从CCD输入输入的图像数据,所以图像数据被顺序地存储在存储器中。 另一方面,当在系统控制单元之外执行扫描器图像处理时,输入图像数据被顺序地存储在存储器中。
