PURPOSE:To eliminate the need to design interface boards matching with various computers and to simplify the constitution by decomposing one byte image data into two-byte image data, and converting the data into ASCII codes and transmitting them in standard serial transmission format. CONSTITUTION:On the side of the image reader 1, one-byte image data are converted into two-byte image data, which are converted into ASCII codes consisting of 0-9 and A-F and transmitted in the standard serial transmission format. On the side of a personal computer 3 which receives the data, the received two-byte image data are restored to the one-byte image data. Thus, the image data are decomposed and converted into the ASCII codes, which are transmitted in the standard serial transmission format, so that the data can be transmitted by utilizing the standard serial transmission format that the personal computer 3 originally has. For example, the one-byte image data are decomposed into the higher-order four bits and lower-order four bits, which are converted into the ASCII codes of 0-9 and A-F through a conversion table. |
