To accomplish this, this memory access system monitors a use-memory-bandwidth which indicates a total of memory bandwidths used between a memory and a plurality of masters, and determines whether the use-memory-bandwidth is equal to or larger than the first threshold. Based on the above-described determination result, this memory access system also restricts access to the memory by a master of low priority out of the plurality of masters.

An image reading apparatus capable of efficiently performing shading correction. The image reading apparatus includes a reading unit that is rotatable for reading an original. A CPU causes the reading unit to read, while the reading unit rotates after reading an image of the original, image data for use in correction of the read image. The CPU performs the correction using the image data read by the reading unit.

An image processing apparatus and a method of controlling the same according to the present invention, displays a preview image by inputting image data read in a two-page spread mode in which two facing pages of a document are read and divided into two pages, and when a first area of one of the divided pages in the two-page spread mode is specified on the displayed preview image, the first area specified is reflected on a second area to be specified of the divided other page. Image data of the first and the second area is extracted from the image data read in the two-page spread mode.

Image processing apparatus, method of controlling the same, and storage medium

A first information processing apparatus receives file information from a second information processing apparatus when the second information processing apparatus is switched to a power saving state. When the first information processing apparatus receives a file information acquisition request, which is directed to the second information processing apparatus from another apparatus, the file information that has been received from the second information processing apparatus is sent to the other apparatus. The first information processing apparatus acquires by proxy a file that is to be stored in the second information processing apparatus and sends the file acquired by proxy to the second information processing apparatus when the second information processing apparatus is restored to the normal power state.

Information processing system, information processing apparatus, and information processing method

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.

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

A semiconductor integrated circuit includes a plurality of internal blocks, a supply unit, and a control unit. The supply unit is configured to supply a clock signal to each of the plurality of internal blocks. The control unit is configured to detect power consumption in the semiconductor integrated circuit and to control the supply unit to start supplying the clock signal to each of the internal blocks one by one if the detected power consumption has stabilized.
