摘要： A scanning device includes a scanning mechanism, a memory, a processing mechanism, and a scan rate adjustment mechanism. The scanning mechanism scans a media sheet having an image thereon at a variable scan rate, to yield raw data. The memory temporarily stores the raw data. The processing mechanism converts the raw data within the memory into processed data. The raw data is removed from the memory as the raw data is converted. The scan rate adjustment mechanism adjusts the variable scan rate, based on one or more of an amount of free space within the memory, a fill rate at which the raw data is filling the memory, and a removal rate at which the raw data is being removed from the memory, so that the memory does not become completely full.

摘要： An image reading apparatus includes a roller which transports a sheet, a motor which drives the roller, an image sensor which reads data from the sheet and a control unit which synchronizes a read timing of the image sensor with a drive timing of the motor in response to change in the drive timing of the motor. Accordingly, when transporting an sheet is temporarily stopped, the transport speed can be changed as desired, whereby the shock caused by changing the transport speed is more lightened and if the resolution to read the original is high, a discrepancy in the data read by the image sensor caused by temporary stop of transporting the sheet can be also suppressed.

摘要： In the case in which an image processing mode is a high-speed copy mode in which follow-up control is possible, setting is made to perform “follow-up control” for setting a mode for not compressing an image or a fixed length compression mode for an image read by a scanner, storing an inputted image in a memory in accordance with the setting, and outputting the image stored in the memory to a printer during scanning. Consequently, image input/output processing from input and storage of an image in the memory until output of the stored image can be performed at high speed.

摘要： A method for compressing data includes transmitting a requested compression factor such as a quality factor known in JPEG compression, to a scanner or like peripheral device. The type of communication link between the scanner or like device and a host computer is identified, and based on the communication link type, the requested compression factor is altered to generate a new compression factor subsequently used to compress the data. The amount of buffer, such as scan buffer, used by the scanner or peripheral device may also be used to alter the compression factor prior to compression.

摘要： An image processing system and method wherein image data is compressed and written to memory. The system includes a first controller, a second controller, a first detector, a third controller and a second detector. The first controller sequentially executes a reading and an image processing of image data from memory. The second controller sequentially executes a re-reading and an image processing of the image data from memory. The first detector detects insufficiency of empty capacity of the memory based on a size of image data of one page compressed at a predetermined compression rate. If insufficient memory for new image data is detected, the third controller writes new image data after a termination of the image processing of the image data of at least one page previously stored. The second detector detects overwriting by the third controller of the new image data on the stored image data.
