Abstract: The image processor comprises a switch that divides image data into m×n pixels, having n lines with m pixels per one line; a group of line memories that store the divided image; a compression device which batch compresses the image data of m×n pixels. Further, a command control unit provides control so as to send the (n−1) lines of image data among m×n pixels of image data to the group of line memories, and the remaining one line of image data directly to the compression device 902, and to send the m×(n−1) pixels of image data stored in the line memories to the compression device.

Abstract: A method and apparatus for image compositing in an apparatus a device in which available memory is at a premium are disclosed. The apparatus includes a first memory that receives a video input signal, in multiple portions. The first memory has a storage capacity less than the entire video image. Data within the first memory is encoded to form encoded video image portions. The entire image is thus encoded, video image portion by video image portion. A second image is combined with image portions in the first memory prior encoding such video image portions. The apparatus may, for example, be an electronic component or components forming a video or image processing pipeline, used in a portable 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。

Abstract: In an image processing method and apparatus for decoding and displaying input encoded data, the upper limit value of the data size to be stored in a memory that stores fragmented encoded data which form image data is set. It is checked based on the data size already stored in that memory, the upper limit value, and the data size of the input encoded data, if that input encoded data can be stored in the memory. If it is determined that the input encoded data cannot be stored in the memory, a region to be deleted in the image data of the data stored in the memory is determined. Data included in the determined region to be deleted is deleted for each fragmented data as a unit. If it is determined that the input encoded data can be stored in the memory, or after the data is deleted, the input encoded data is stored in the memory.

Abstract: A transmission system and a method of correctly transmitting scan data within a scanner. The transmission system includes a synchronous dynamic memory and a buffer unit. The synchronous dynamic memory serves not only as a storage unit for holding data, but also provides a masking function for processing the last remaining scan data. The buffer unit is coupled to the synchronous dynamic memory for holding the scan data sent by the synchronous dynamic memory.

Abstract: Two modes for releasing a memory, a mode in which the memory is released page by page and a mode in which the memory is released block by block are provided and one of the modes is selected in accordance with the amount of received data to enhance the reliability of the reception and recording with a smaller capacity of image memory. When the reception of the data is started and the image data is filled in the memory block, the recording of the received image to a recording medium is started. Each time the recording of the memory block is completed, the release mode of the image memory is set. Namely, when the reception of the page recorded in the memory hold mode is not yet completed and the remaining capacity of the image memory reaches below a predetermined capacity, the recorded memory blocks are released and the release mode is switched to the memory release mode.
