Abstract: A scanning controller, a scanning apparatus and a method for performing the scanning controller are disclosed herein. The scanning controller includes an image data processing unit, a memory control unit, a dummy line control unit, a buffer condition control unit, a motor condition control unit, a motor controlling unit and a relation control unit. Based on at least one of several predetermined contrastive relationships among each stored data amount with regard to an image buffer and its corresponding motor move timing, the relation control unit controls generation of a motor move timing from the motor controlling unit to drive a motor with variance of a scanned data generation rate and simultaneously enable determination of the dummy line control unit on which part of scanned image data should be skipped by catching of the image data processing unit.

Abstract: An image processing apparatus includes an image capture apparatus with a reduced size for capturing still image data. An extracting circuit extracts at least an area of still image data. A dividing circuit divides the area extracted by the extracting circuit into a plurality of first through nth areas. A memory circuit has a storage capacity smaller than a storage capacity required to store the still image data, and stores at least a portion of the image data of the first through nth areas provided by the dividing circuit. A transfer circuit transfers the image data stored in the memory circuit to an external device.

Abstract: An image reading apparatus prevents degradation of image quality and a delay in the image reading time which are caused by interruption of reading of image data. A speed at which a host computer reads image-data from an image reading apparatus and temporarily stores it therein is examined. If the resulting speed is lower than a reference value which has been set so that an operation to avoid an overflow of a buffer RAM in the image reading apparatus may not be caused, the sub-scanning speed of the image reading apparatus is set lower, and the image is read at the lower speed.

Abstract: Image data from a document being scanned is encoded and stored in an image memory (4). As soon as the amount of data in the image memory (4) reaches a pre-set limit, the machine (F) begins transmission of the data to a designated recipient from the image memory (4). If it is determined that there is insufficient memory to store image data of a document being scanned in the image memory (4), the machine suspends scanning of the document, and transmits all the encoded data to the recipient from the image memory (4). Then, the machine (F) resumes the scanning and encoding operations. When it resumes scanning the remaining pages of the document and encoding the resultant image data, it transmits that data directly to the remote party without first storing that data into the image memory (4).

Abstract translation: 被扫描的文件的图像数据被编码并存储在图像存储器（4）中。 一旦图像存储器（4）中的数据量达到预定限制，机器（F）开始从图像存储器（4）向数据指定的接收者发送数据。 如果确定没有足够的存储器来存储正被扫描的文档的图像数据在图像存储器（4）中，则机器暂停对文档的扫描，并且从图像存储器（4）将所有编码数据发送给接收者， 。 然后，机器（F）恢复扫描和编码操作。 当它恢复扫描文档的剩余页面并对所得到的图像数据进行编码时，它将该数据直接发送到远程方，而不先将数据存储到图像存储器（4）中。
