Abstract: After reading a predetermined number of predetermined blocks for each of a plurality of image data, a first image read unit 13 reads out the plurality of image data read in parallel by repeatedly switching the designated order of the plurality of image data. A JPEG compression unit 14 performs image compression on the plurality of image data read out in block units by the first image read unit 13, image-compresses a predetermined number of the blocks for each of the plurality of image data, and then inserts an identifier after the last block of the predetermined number of blocks.

Abstract: A scanner system includes a scanner, computers sharing the scanner, a network connecting between them, and a scanner controlling apparatus connected between the network and the scanner. The computer includes a device driver to control the scanner and notify the scanner controlling apparatus of an event in the device driver, and an application to control the device driver, and transmit and receive data to and from the scanner controlling apparatus. The application activates the device driver in response to the trigger input from the scanner controlling apparatus. When activating, the device driver receives image data from the scanner controlling apparatus through the application.

Abstract: When the size of a printing paper is smaller than a half of the whole area used for expanding the printing data, a method and apparatus for controlling high speed printing in a printer device, having a bit-map memory, a data transfer circuit for transferring video data on the bit-map memory to a printer, and a copying unit for copying the dot-data within a rectangular region on the bit-map memory, include copying the dot-data expanded in a first area on the bit-map memory into a second area that does not overlap with the first area; and sending the dot-data to the printer, and simultaneously expanding the printing data of the next page in the first area. When the size of a printing paper is smaller than the whole area, the method and apparatus include copying the dot-data expanded in a first area on the bit-map memory into a second area that overlaps with the first area in one part; sending the dot-data to the printer; and expanding the printing data of the next page in the first area partially in parallel.
