摘要： An information readout apparatus reduces an effective wait time and shortens access time when information recorded on a magnetic disc is read out by effectively utilizing a wait time of a disc rotation. When a sector on the magnetic disc on which a magnetic head is currently positioned is between a start address and an end address, information behind the current sector is buffered and the sequence of the buffered information is rearranged as required and read out so that overlapped readout of the previously read information from the magnetic disc is prevented to shorten the access time. The current sector address is compared with the start address and the end address to process the information.

摘要： An information processing system processes identification of a track address and a sector address, control of timing, control of reading and writing of data and error checking with reduced intervention of a CPU to a magnetic disc unit so that the throughput of the CPU is increased and performance for data processing is improved. A predetermined number of sectors are processed in sequence, and a greater number of sectors than the number of sectors in one track can be processed by hardware implementation. This system can also control magnetic disc units having different formats.

摘要： The present invention has a transmission side apparatus to which an image to be transmitted is inputted, and an outline vector along the edge of the inputted image is extracted. The transmission side apparatus transmits data of the extracted outline vector to a receiving side apparatus via a data line. The receiving side apparatus reproduces the image in accordance with received outline vector data so as to output it to a predetermined visible image generating apparatus.

摘要： When an image is input, that input image is separated into a halftone region, such as a photograph, and a binary region, such as a character/line. Contour vector data along an edge of the separated binary image region is extracted. Regarding the binary image region, when the input image is to be enlarged or reduced and then output, individual coordinates in the extracted contour vector data are enlarged or reduced to reproduce the binary image.
